Interpretor Scummvm: 0.10.0 Preview 1

System GP2X

Scumm engine interpretor for running Sam & Max, Monkey Island etc.. news:

This is a little bit of a short notice preview release (I have had other commitments that have kept me from ScummVM).

I would be eternity grateful to anybody who gives this build a bit of a road test over the next 24 hours or so and reports back issues to me as the aim is to release 0.10.0 final in a few days.

Those of you who follow SVN builds should find most of your feedback and 'easy' bug fixes have made this release.

# Main changes in this build since the last SVN release: Built from latest 0.10.0 pre-release SVN code (and only that code so ARM mixer and DXA speedups from HEAD SVN/local patch builds are NOT in this release)
# Support for "predictive text" entry in AGI games as long as a suitable dictionary is available (included in zip) - You can access the predictive text dialogue in AGI games with "Left Trigger + A" when you want to type something.

* Several (too many to list) HD GUI fixes. If you are an HD user, you will be pleased at the new tweaks.
* Added 720p and 1080i versions of all the skins. If you are going to run in 720p or 1080i, don't try to configure everything yourself (it takes FAR too long). Change to a 720p or 1080i skin and this will setup the GUI for you. This method will only require minor tweaks for your TV.
* The HD setting is now applied from the skin ini file.
* Removed a lot of dead code.
* Removed the TV calibration option since I assume it's not really being used by anyone. This frees up more RAM.
* The database files are loaded/unloaded on the fly to free more RAM
* Fixed the virtual keyboard to display correctly in 720p and 1080i.
* Added larger font sizes for the game guide and GUI (the game guide was too small to read in 720p and 1080i. This is fixed)
* Loading game guides 1MB and up should work now in HD resolutions (but don't go too crazy with the file sizes).

Notes:
* There are a few RAM related issues I need to fix, but I wanted to get this version out. 3.0 and up were unusable in HD resolutions. Now that's fixed.

Install:
Extract and copy all files and folders to your Xbox hard drive. Run "default.xbe" to start. Delete your old ZsnexBox.ini and Path.ini files if upgrading.

Skipping Ahead

Dox decided to hack around a bit with the driver, and found a way to skip some of the tests. As a result JoJo and JoJoba actually now execute some of the game code, rather than just the bios. They both hang after the Japan warning however. The code appears to be stuck in a big loop, dong not much at all.

Doing this properly is something of a pain in the backside due to the way MAME works. The games execute code from FlashROMs, however due to the way FlashROMs are accessed MAME must map them as Read/Write handlers in the driver, not blocks of RAM/ROM. MAME’s CPU cores don’t handle executing code from Read/Write handlers well, nevermind *encrypted* code (with the possibility of *decrypted* data) from such handlers. This is probably going to require some rather ugly hacking around.

Its interesting to note that JoJoba is the NCD set, while JoJobaa appears to be a standard set. They both however still check for the CD, so I’m guessing there must be something else to it too.

It’s also interesting to note that the dates these things are booting up with seem completely wrong. Maybe it’s not running the correct boot code.

Of course, everything is stuck with error messages at the moment as I haven’t made much more progress with the CD-Controller emulation yet. I found that the amd / wd33c93 is supported in MESS (wd33c93.c), I don’t know how well it works tho, it’s only used by the Indy driver.. I guess I’m going to have to find out.

Emu WIP Daedalus PSP WIP, Tracking down the SSB Dynarec Bug

'Yesterday I said I'd provide some more details about the Super Smash Bros. dynarec fix. The actual fix is fairly straightforward, but I thought the process of tracking down the issue was quite interesting and worthy of a couple of blog posts.

When I first started looking at SSB I noted that although the game ran fine without dynarec, it would always hang when trying to enter the main entry with dynarec enabled.

I've been programming professionally for around 6 years now and I can safely say that debugging dynarec bugs is one of the hardest categories of problems I've ever had to work on. For a start, because the code is generated on the fly, you don't have the luxury of source level debugging, and without spending time reverse engineering the original rom image, you don't even know what the generated dynarec code is meant to be doing. It's very much like working blindfolded.

And it gets even worse. I've fixed dynarec problems in the past which were the result of generating incorrect code for a fragment over 500 million instructions into emulation. This would be bad enough, but it can be many thousands of instructions later before this causes emulation finally diverges from the correct path. Just identifying the exact point at which the emulation starts to diverge from the correct sequence of instructions can be like finding a needle in particularly large haystack. While blindfolded

Over the years of trying to debug problems like these I've built up a set of tools and learned a few tricks along the way which you might find quite interesting. Although I'm going to talk about them in the context of tracking down this dynarec issue, I've found some of the techniques useful in solving other problems so you might find other ways of applying them too.

One of the first things I do when trying to identify a dynarec issue with Daedalus is to see if the problem is reproducible on the PC build of the emulator. Although it is possible to use GDB with PSPLink, I've never got this up and running and I'm much more comfortable debugging with Visual Studio. Also, working with the PC build is usually much faster than working with the PSP build (debug builds run around 10x faster on the PC, and build times are much quicker.)

Not all dynarec issues can be debugged in this way - the PSP and PC builds have different code generation back-ends (i.e. MIPS and x86 code generation respectively) so bugs in the MIPS code generation won't usually be reproducible in the PC build. The dynarec system in Daedalus shares a common frontend (trace selection and recording) between the two platforms, which means that if I can reproduce the problem on both platforms, I can narrow down the likely location of the bug to this area.

Fortunately this particular bug manifested itself in both the PC and the PSP builds, so I knew that if I fixed the bug on the PC build, it should fix the PSP build too. What I needed to find out next is what the emulator was doing differently when dynarec was enabled compared to when it was disabled.

If dynarec is running without errors, then the sequence of executed instructions should exactly match that executed with dynarec disabled. If I could log details about all the instructions executed with dynarec disabled, and again with dynarec enabled, I should be able to compare the two logs to figure out the exact point at which dynarec is going out of sync. This all relies on the fact that the emulator is totally deterministic, i.e. that running the emulator twice in succession with the same settings should give exactly the same results.

Unfortunately, for a variety of reasons my dynarec solution doesn't produce identical results to interpretation, the main reason being that for performance reasons I can only handle vertical blank and timer interrupts on the boundaries between fragments. For example, with dynarec disabled, the first vertical blank interrupt might occur exactly on the 625,000th instruction, but with dynarec enabled with might not occur until the 625,015th instruction. This means that the logs diverge at the instant the first VBL fires, and never regain synchronisation.

When I was originally developing the new dynarec system I put a lot of effort into writing a fragment simulator, the idea being that rather than executing the native assembly code for a given trace, I could keep track of the instructions making up the trace and interpret these individually instead. Theoretically fragment simulation is identical to dynarec code execution, even down to the way I handle VBLs and timer interrupts, and it's been very useful at identifying bugs in the dynarec code generation. What's particularly useful about fragment simulation however is that I can enable a setting which makes it handle interrupts exactly in the same way as the non-dynarec core, i.e. interrupts are handled precisely rather than on fragment boundaries.

# Essentially Daedalus has four modes of operation: * Dynarec + fragment execution
# * Dynarec + fragment simulation (imprecise interrupt handling)
# * Dynarec + fragment simulation (precise interrupt handling)
# * Interpretative core

This tool is particularly powerful, because if I can ensure that dynarec+fragment execution is equivalent to dynarec+fragment simulation, and that dynarec+fragment simulation is equivalent to running the interpretative core, then I can use the transitive properties of these relations to ensure that dynarec+fragment execution is equivalent to running the interpretative core. Fragment simulation allows me to bridge the gap between these two modes of operation which would otherwise be very difficult to compare.

I think that's long enough for one post. Tomorrow I'll talk about how I used this technique to help track down the SSB dynarec bug.'

Emulator Snes9xGx2.0.1b6a Mod

System GC/Wii

Snes emu, news:

Highlight: Turbo Mode Speed toggling available(Press the C-Stick up/down to change your speed) this allows you to change your emulators turbo speed to the following settings: 2x, 4x, 6x, 10x, 12x, 15x, and 20x.

I felt this was a worthy modification because every one of these framerates runs silky smooth(Unless your playing a GFX Chip game such as Star Fox as it already has a low framerate).
1.) Z Trigger is now used for Turbo Mode.
2.) Z Trigger can be changed back to select by simply moving your C-Stick to the right and switched back to Turbo by doing it again.
3.) NGCZoom has temporarily been disabled to allow my speed up function usage.(Will add another menu option later).

The Source and compiled .dol files can be found below.

Sorry for anyone using SDSlot A I mistakingly used my own test file for this update and it was not named -sdslota. It should be corrected now .

IMPORTANT: NGCZoom in the Emulator Options Menu must be enabled in order for the Turbo Framerate +/- to work. Make sure you view the Usage.txt file before playing to see what new features are included.

WARNING: FREEZE STATES ON A MEMORY CARD ARE AT RISK OF BECOMING CORRUPTED UNTIL CRUNCHY2 Fixes the problem!

and heres the news:

It's one of those times again, where every single emulator on this site has been updated simultaneously. Every time I do this I say something about never wanting to have to do this again, but invariably something comes up and it proves necessary. Just to keep with tradition, I really hope this will be the last time, not that there's any chance of you, the reader, believing that it will be.

# The following changes have been made to the shell, which affect all emulators using it: Fixed a nasty crash that could occur when using high requirement blitters (HQ4x/etc) on slower multiprocessor machines.
# Added a hidden preferences option to disable the information placards ("Emulator Reset", etc). To change this, open the preferences plist file in a text editor.
# Added proper code interface for getting the mouse position on display. Nestopia uses this for Zapper support, and TEO/Thom use it replacing a horrible hack used previously.
# Resolved assertion failure, ce_file.c, line 379, when saving a saved state with the same name as an existing file. Thanks to about two hundred people for reporting this one

The following changes have been made to individual emulators:
# (BSNES) Resolved an issue where certain compressed ROMs would crash the emulator on Intel machines.
# (BSNES) Note that this will probably be the last version of BSNES to be compatible with PowerPC Macs. I'm going to sync up with the latest code following this release, which will almost certainly be Intel only.
# (Genesis Plus) Added support for Blargg's awesome NTSC simulation code. Note that there is a black bar down the right hand side of the display in this mode which is not considered a bug; my shell only supports output sizes with a multiple of eight pixels, and I felt that having a black bar was preferable than losing the right hand four pixels of the display.
# (KiGB) Added a choice of different palettes for classic gameboy emulation.
# (Mugrat) Rewrote input handling code, fixing the long standing bug with the second fire button.
# (Nestopia) Synchronised with the latest release for Windows.
# (Nestopia) Worked around a crash in NTSC mode caused by the Xcode optimizer.
# (Nestopia) Added support for the Zapper light gun (using the mouse).
# (Nestopia) Added support for configuring dip switches in VS games.
# (Nestopia) PAL games now play at the correct speed of fifty frames per second.
# (Nestopia) Added support for the mouse, as used by Educational Computer 2000 (Ru). Note that the mouse movement isn't perfect yet.
# (Nestopia) Added support for the barcode reader. A menu command has been added which sends random barcodes to the current game.
# (Oric) Worked around a bug in the Xcode optimizer that caused HIRES mode to break. Thanks to Pascal Leclerc for the report and detailed test case.
# (SMS Plus) Added support for Blargg's awesome NTSC simulation code.
# (TEO) Now uses shell API for handling mouse movements.
# (Thom) Now uses shell API for handling mouse movements.

emu wip Daedalus PSP WIP, Tracking down the SSB Dynarec Bug Part 2

On Monday I talked about the fragment simulator and how this could be used to help track down bugs in the dynarec implementation. In this post I'm going to talk a bit about a tool I use mostly for regression testing, but also to help determine the exact point at which the fragment simulator and the interpretative core go out of sync. It's a bit of a long post, so apologies in advance

Daedalus can be compiled with a flag which enables a special 'synchronisation' mode. This build configuration creates an instance of a synchronisation class which can be initialised in one of two modes - either as a producer or as a consumer. At various points during program execution I pass information about the internal state of the emulator to the synchroniser for processing. In the case of the producer, it simply writes this data out to a file on disk. The consumer is a bit more interesting; it reads data of the required size from disk, and compares this 'baseline' value against the value provided by the emulator. If these two values are found to be different, the synchroniser knows that things have drifted out of sync and it can trigger a breakpoint and drop out into the debugger.

This technique relies on the fact that the emulator is deterministic, i.e. running the emulator twice in a row with the same inputs generates exactly the same results. By 'inputs' this means not just the same rom image, but external inputs such as data from the controller must match exactly too. Obviously pressing buttons on the controller in exactly the same order with the same timings would be impossible to duplicate, so the other function the synchroniser performs is to record input from the pad in the case of the producer, or play input back in the case of the consumer. Other external input, such as calls to timer functions (e.g. time(), QueryPerformanceCounter() or rdtsc) can be synchronised in the same way.

The synchroniser works with as few or as many sync points as you provide. For debugging very simple problems, you can get away with just checking the value of the program counter as each instruction is executed. For more tricky problems you can end up adding many more sync points - for instance you can synchronise the entire register set after every instruction to ensure that the synchroniser catches any instruction which generates a different result from the baseline.

I add sync points to Daedalus using a set of macros. When synchronisation is enabled, the macros expand out to calls to a virtual method on a global instance of the synchroniser class. An example sync point in the code might look like this:

u32 pc = gCPUState.CurrentPC;

SYNCH_POINT( DAED_SYNC_REG_PC, pc );

OpCode op;
if( CPU_FetchInstruction( pc, &op ) )
{
CPU_Execute( pc, op );
}

The interesting line here is the SYNC_POINT macro, which synchronises on the current program counter value. For producers, this just writes the value of 'pc' to disk. For consumers, it checks that the value we have for 'pc' matches the one read from disk.

The DAED_SYNC_REG_PC argument is simply a flag to describe what is being synchronised. Another global constant allows easy control of what is synchronised:

enum ESynchFlags
{
DAED_SYNC_NONE = 0x00000000,

DAED_SYNC_REG_GPR = 0x00000001,
DAED_SYNC_REG_CPU0 = 0x00000002,
DAED_SYNC_REG_CCR0 = 0x00000004,
DAED_SYNC_REG_CPU1 = 0x00000008,
DAED_SYNC_REG_CCR1 = 0x00000010,

DAED_SYNC_REG_PC = 0x00000020,
DAED_SYNC_FRAGMENT_PC = 0x00000040,
};

static const u32 DAED_SYNC_MASK(DAED_SYNC_REG_PC);

#define SYNCH_POINT( flags, x, msg ) \
if ( DAED_SYNC_MASK & (flags) ) \
CSynchroniser::SynchPoint( x, msg )

If I want to enable more thorough debugging, I can change DAED_SYNC_MASK and OR in more values:

static const u32 DAED_SYNC_MASK(DAED_SYNC_REG_PC|DAED_SYNC_REG_GPR);

Changing the mask value requires the emulator to be rebuilt from scratch and the baseline synch file to be recreated. This is a bit time consuming but doing it in this way means that the compiler can optimise out any synch points which we aren't interested in, keeping things running as quickly as possible.

One problem with this technique is that the synchroniser can quickly generate a massive amount of data, so much that most of the execution time is spent shifting this data to or from disk, slowing debugging to a crawl. In the example I gave on Monday, it can sometimes take over 500 million instructions before things go out of sync. Even when just synchronising on the program counter, that's over 2GiB of data that needs to be read/written to disk. When you throw in more sync points such as register sets (the GPR registers on their own are around 256 bytes) this can very quickly become impractical. To get around these limitations in Daedalus I gzip the stream of data on the fly which compresses the data significantly. Another trick I use is to hash each register set to a 32bit value and synchronise on this value instead. When using both these techniques the sync files typically end up around 100-200MiB, which is much more manageable.

One of the main uses of this synchronisation code is for regression testing optimisations I've made. I can take a 'known good' build of the emulator and initialise the synchronisation class as a producer to generate a baseline sync file. I can then take a modified version of Daedalus with the optimisations that I want to test, and initialise the synchroniser as a consumer. If the synchroniser detects that things have gone out of sync, then I know that my changes are buggy, and I can investigate why they're not working as planned. It's worth noting that even if everything stays in sync, this isn't a guarantee that my changes are bug-free, but it's a pretty good indication that they're ok.

I also use the synchronisation code to debug tricky dynarec issues. When debugging these types of problems I typically start off by disabling the dynarec engine and setting up the synchroniser to produce a baseline for testing. I'll then re-enable dynarec, but using the fragment simulator with precise interrupt handling (see the end of Monday's post for more on this) and run Daedalus with the synchroniser in consumer mode. Theoretically, as soon as the dynarec code gets out of sync with the interpretative core, the breakpoint triggers and I can investigate things more closely in the debugger.

This is exactly the process I used to track down the Super Smash Bros. bug. When I ran the emulator with the synchroniser in consumer mode, it detected that the program counter was different from the expected baseline value after exactly 387,939,387 instructions had been executed. I'd like to think that an error rate of 2.57e-7% wasn't all that bad, but apparently it is

Now that I knew the point at which the emulator was going out of synch, I set a few breakpoints in the emulator to see what exactly was happening. My usual trick is to disassemble the executed instructions just before and after things diverge, and see what's different. Here are snippets from the 'good' and 'bad' logs as things go out of sync:

Count 171f7c35: PC: 80132500: LW ra <- 0x0014(sp)
Count 171f7c36: PC: 80132504: ADDIU sp = sp + 0x0018
Count 171f7c37: PC: 80132508: JR ra

Count 171f7c39: PC: 80132ae8: JAL 0x80131fb0 ?

Count 171f7c3c: PC: 80131fb4: SW ra -> 0x0024(sp)
Count 171f7c3d: PC: 80131fb8: SW s0 -> 0x0020(sp)
Count 171f7c3e: PC: 80131fbc: CLEAR a0 = 0
Count 171f7c3f: PC: 80131fc0: CLEAR a1 = 0

Count 171f7c35: PC: 80132500: LW ra <- 0x0014(sp)
Count 171f7c36: PC: 80132504: ADDIU sp = sp + 0x0018
Count 171f7c37: PC: 80132508: JR ra
Count 171f7c38: PC: 8013250c: NOP
Count 171f7c39: PC: 80132ae8: MTC1 at -> FP06
Count 171f7c3a: PC: 80132aec: NOP
Count 171f7c3b: PC: 80132af0: SWC1 FP06 -> 0x0018(a0)
Count 171f7c3c: PC: 80132af4: LBU v0 <- 0x4ad1(v0)
Count 171f7c3d: PC: 80132af8: ADDIU at = r0 + 0x0008
Count 171f7c3e: PC: 80132afc: BEQ v0 == at --> 0x80132b24
Count 171f7c3f: PC: 80132b00: ADDIU at = r0 + 0x0009

I've highlighted the instruction at which the synchroniser detected the PCs were out of sync. In the good trace (top) the PC is 0x80131fb0, but in the bad trace it's 0x80132af0. If you have particularly sharp eyes, you'll notice something else - two instructions before the code goes out of sync, the good trace executes a jump instruction to 0x80131fb0, but the bad trace is performing a MTC1 op (Move To Coprocessor 1)

This provides a particularly good example of one of the main weaknesses with the synchroniser - it's only as good as the synch points you set up. Because I was just synching on the program counter, it didn't detect the fact that the emulator executed an entirely different opcode two instructions previously. In this particular case I was fortunate in that the real source of the problem was very close to the location identified by the synchroniser, but sometimes the cause and effect can be separated by many thousands of instructions.

Fortunately it's easy enough to add new synch points in the code to detect issues like this, but adding too many synch points causes the emulator to slow to a crawl and makes debugging impractical. I've found the best approach is to start off with as few synch points defined as possible (ideally just the program counter) and slowly introduce more synchpoints as required. This is all very easy to do using the DAED_SYNC_MASK flag discussed above.

Getting back to SSB, it looked like I had found the root cause of the problem - somehow the rom was replacing the instructions in memory, essentially a form of self-modifying code (it's more likely it was just loading a new section of code into RAM from ROM, but it's still essentially self-modifying). The dynarec system was oblivious to these changes and so it ended up trying to execute stale instructions that it had cached when creating the fragment, potentially many thousands of cycles ago.

Dealing with self modifying code in dynamic code generators is generally very tricky. In Daedalus I've been relying on the fact that most roms are well-behaved and flush the instruction cache when they modify memory containing executable code. When I detect a instruction cache invalidate (through the MIPS CACHE opcode) I simply dump the entire contents of the fragment cache and start from scratch. This might sound a little heavy handed, but the way that I link fragments together makes it very hard to unlink small sections of code that has been invalided. Flushing the cache is very quick, safe and has a few advantages such as purging cold traces that are no longer being executed any more.

Ironically, the reason the dynarec was failing to cope with SSB wasn't due to a bug in Daedalus - it was due to a bug in SSB that just never happened to be a problem on a real N64. After updating memory with the new instructions SSB should have been invalidating the instruction cache to ensure that it didn't contain stale code, but for whatever reason it failed to do this. The only reason the rom runs correctly on a real N64 is that by the time it comes to execute the modified instructions, the instruction cache has been refilled a number of times and so the stale instructions are no longer cached.

Even though this isn't Daedalus's bug, it still needs to work around the problem. I'll leave this discussion for a future post though - this one is long enough as it is

* The sound processing part and additionally, a detailed part was sped up.
* The speed and timing were brought close to a real machine more. In demo scene of "3x3 Eyes", the gap of the sound was solved. I think that the operation timing improved in other games, too.
* In ending of "Splatterhouse", the staff roll was made the same expression as a real machine.
* In demo play of "Magical Chase", the problem that the noise sound had been emitted when having started was solved.
* Additionally, a detailed part has been improved and corrected.
* I was deeply moved by Sato Takuma's running in the Canada F1 Grand Prix.
Therefore, it was possible to work more better this time(v1.09).

2. The screenshots could be faked.
3. We censored the name of Zelda TP.
4. We had no availible downloads.
5. We wanted money for the insider's sections (we didn't had time to post the news about our "Insider's section" because you were too fast unveiling the truth).

But why you believe this?

They didnt have a real proof that they make an emulator.

Their screenshots could be faked.

We censored the name, they didn't almost show the name of the game.

They had no availible downloads. Why not? Because they want that their emulator is better than this one:

Everybody believes in Dolphin because you can download and test it.

And now the point where we could go crazy. They wanted 7 USD for some pics and video stuff in their "N'sider section" Who pays money for screenshots of gamecube games?

Emu WIP Daedalus PSP WIP, Multiplayer thoughts & R12 release date

Multiplayer Thoughts

In response to a recent post, Zeus asked an interesting question:
'I know you've probably been bugged by people on this before, but how hard would multi-player be to implement? More importantly, do you think that there is enough bandwidth, and low enough lag, to allow a host-client multiplayer setup to be playable? (ie, with one psp "hosting" the game and doing the emulation, while the other(s) just receive screen-captures and send back user-input) Or do you think that distributing the computational workload would be a better approach? (at the very minimum, the audio processor shouldn't be too horrible to move to the client psp(s) )'

I have thought about multiplayer a great deal, but I've never made any plans to work on it - there didn't seem to be much point getting multiplayer working before there were a few multiplayer games running quickly and glitch free. Now that MarioKart and Super Smash Bros. are both working reasonably well, there's obviously going to be a lot more demand for multiplayer support. Before I raise expectations and get anyone's hopes up, I should mention that this isn't likely to happen any time soon.

It would be possible to go down the route of having a host psp which performs emulation and broadcasts the screen to client psps. Sony's Remote Play between the PS3 and PSP shows that this kind of 'dumb terminal' approach can work in the right situations. That's with the PS3 doing the grunt work of compressing the framebuffer and sending it over to the PSP. For for a PSP running Daedalus as a host, I'm not quite sure there would be enough spare horsepower to compress the framebuffer and audio and then send it to 1 or more connected clients.

Also, I don't think that it would be possible to decouple the audio processing from the main cpu thread so that this work could be distributed to one of the clients. Although the audio and graphics processing is notionally run in parallel on the RSP (the N64's coprocessor), access is still serialised between audio and graphics tasks so they have to be completed in order. Performing audio processing on a client PSP would just mean that graphics processing on the host would have to wait until the results of the audio processing were received.

The approach that I'd been considering was running Daedalus in lockstep across 2 or more connected PSPs. As I mentioned previously Daedalus can run deterministically if external inputs such as pad input and timing sources are synchronised. What this would mean would be that every time the rom queried the pad status, each connected psp would have to synchronise its view of the pad input with the host. This would mean sending just 64 bytes across the network from the client to the host and back. This information would have to be sent over a TCP connection rather than UDP as we have to ensure that every PSP sees the exact same input (actually, client->host communication is a bit less critical so it may be possible to transmit this information over UDP if it helps improve lag.)

One really cool feature about this approach is that as each PSP would be responsible for rendering its own display, it would be possible to scale up each viewport to fill the display; rather than playing 4-player Mario Kart or Goldeneye at 160x120, you'd be able to play at 320x240 (or 480x272 if you wanted to scale it up to entirely fill the PSP's screen).

As I said at the start of the post, this isn't something that's likely to happen any time soon, but if and when it does happen, it will be amazing

R12 Release Date

A number of people have been asking in the comments when R12 is going to be released.

There are still a number of things I want to work on. Now that Super Smash Bros. is running nice and quickly with dynarec enabled, I want to spend a week or so polishing the graphics and trying to make it as playable as possible. Although Goldeneye is running with dynarec in R12, it still needs a lot of work before its playable, so I'm not going to spend any more time on it for R12.

I'm going on holiday at the end of June, so I'd like to have R12 released before then. I'll aim for next weekend (23rd/24th June) but it may end up being as late as the 26th/27th.

Emu WIP CPS3 Colour & Sound

June 16th, 2007
CPS3 Colours

The Palette DMA is now emulated, so the text layer is looking a lot nicer now.

Note, Warzard / Red Earth still does not boot in MAME, I have no idea why, don’t worry tho, the decryption of it is fine, it’s just not booting for me.

Note 2, ignore the regions, most dumped sets are actually Japan.

Note 3, the strange outlines around the tiles are because they’re being drawn as solid, not transparent.. (mainly due to the fact that there is nothing behind them right now)






June 15th, 2007
CPS3 Sound

No real progress on the Backgrounds / Sprites / Palette i’m afraid. Lots of things have been ruled out, but no conclusions have been made on how it actually gets/decode the data from FlashRoms into RAM yet, it seems to be some kind of external DMA but we can’t find any parameters or what triggers it right now.

On the good side of things, Eeprom access has been fixed, so SFIII / 2 / 3 boot without Eeprom hacks. Warzard still doesn’t boot for some reason, although ElSemi has it booting outside of MAME (it doesn’t reveal any more clues about the backgrounds/sprites work tho)

Also, and this is the main thing I want report here, Phil Bennett has added preliminary sound emulation (as mentioned in the comments of the previous post)

Here is a short OGG recorded from SF3 in MAME. As you can hear, the game is running even if you can’t really see anything apart from the health bars.

NOTE1: The video speed isn't the real speed the game would be going. It's slower due to Hypercam running over it (and using some of the CPU).

Emu WIP CPS3 emulator WIP news

ElSemi's emu is up first for WIP news this time:

more as it happens here (lots of Spanish)

Emu WIP CPS3 Tile / Sprite Data Compression

CPS3 uses compressed data for it’s BG tiles and Sprite Data. The system has a ‘DMA’ list in Video RAM, and when given the command the video hardware will process this list, and copy + decompress graphic data from the FlashROMs into Video RAM for use by the game.

The compression initially looked rather complex, but actually turns out to be much more simple than first thought (although emulation still isn’t perfect)

The basics of it are simple. The first command in the DMA list is a special command, telling the chip to upload a 256 byte table to its internal memory. The Compressed data contains 8 bit values from 00 - FF. Byte with 0×80 set (0×80 - 0xFF) are treated as a lookup into the table it uploaded, replacing one byte, with one word from the table. This allows them to compress the 128 most common words to a single byte instead of a word, thus saving 50%.

After that there is an RLE stage, bytes with 0×40 set are command bytes, telling the chip to repeat the next byte a certain number of tiles. What you’re left with is a series of values between 0×00 and 0×3f, giving 6bpp (64 colour) sprite / bg tiles.

What isn’t quite understood is what happens if there is an RLE command byte followed by an RLE command byte, or if RLE is applied to a 0×80 byte, does it just affect the first value in the table, or do both get repeated etc.

Here are some screenshots, they’re not quite as good as ElSemi’s, probably due to a bug in the code I’m using right now. Also I’ve had to disable the text layer palette for now because MAME can’t handle over 0×10000 colours in a palette without custom drawing functions.

- rom scanner uses SHA-1 now (instead of CRC32)
- archive as a harddrive emulation. Data is decompressed on the fly. Only directory tree is allocated in memory during mount-phase. "file not found error" will be returned if decompression fails (corrupt archive?) Already decompressed files will be left in memory (memory is cheap, repeated decompression can be slow)
- archive support completely rewritten (memory/file leaks possible) Recursive decompression possible (not yet enabled and not fully implemented), not sure if I enable it later or not.. (would enable transparent archives inside archives inside archives etc..)
- work in progress (this is really crazy idea..): xfd (Amiga decompression library) slave library support via separate 68k emulation instance Crazy or very stupid idea, not sure yet.. It would enable full transparent decompression support of nearly every Amiga compression format..
- built-in lha/lzh archive support added
- built-in lzx archive support added (store mode not supported yet)
- "add directory/archive" harddrives: only path is mandatory, volume name (if left empty) is automatically generated from selected path

Emu WIP CPS3 Mame WIP, Sprites.. & Tile Compression Part 2

Sprites..

This is the first shot of some sprites with meaningful tiles. Everything is in the wrong place and upside down at the moment, but you can see where this is heading.

and this is where we stand at the end of the day / night… on our heads.


Tile Compression Part 2

Dox made a suggestion, I implemented it, and now the tile DMA is fixed.

Basically the RLE byte should affect the last normal byte before it, NOT the byte after it. This simplifies the code, and produces much better results.

Emu WIP mame CPS3 WIP update

Sprite zoom

I posted this on Mameworld yesterday because I couldn’t access my site.

Anyway, I’ve hooked up a preliminary spritezoom in CPS3 (this progress is in Mame0116u2) and passed the information on how it works to ElSemi so that he can implement it in his standalone emulator.

Basically each part of a sprite can specify the height / width of that part in pixels, and the number of tiles that are used to cover that height / width. Previously I was using the upper 4 bits of the height / width as the number of tiles instead. After realising that this was wrong and finding the actual # of tiles bit implementing the zoom was fairly straightforward.

JoJo / JoJo Ba have a test mode where you can test the sprites. This is only available when the game is set to ‘Developer Mode’ ( 0×7x region code in the BIOS ) As the current MAME driver is set to this while I work on it, you can access the hidden mode by holding Player 1 button 1 when entering test mode.




Warzard also uses it for the character profiles in the background on the select screen. Compare this to the shot in the previous news post.



Street Fighter 3 3rd Strike uses i during the intro for some portraits, these looked terrible with the previous preview code.




and it’s also used for the ‘Fight’ graphics at the start of the round on most of the games.




there are many other places where it’s used as Capcom made fairly extensive use of it for special effects etc. So having it implemented improves a large number of little things.

CPS3 also has ‘Line Zoom’ and ‘Frame Zoom’ Frame Zoom seems to be some kind of Framebuffer zoom, allowing the player to see a greater / smaller area of the playfield. Implenenting that *fast* in MAME could be a pain I remember having to do similar for ‘Rabbit’ and it slowing the whole thing down significantly due to the overhead of having to render and clear an extended display area. Anyway, I’ll look into it at some point, but first I’d like to look into fixing the remaining sprite palette issues both myself and ElSemi are having. He’s using one sprite colour register, I’m using the other, there must be some way to combine them, or select which one to use.

Palette

I think I’ve fixed the palettes. There was a single bit to select which one to use (the one in the main list, or the one in the sublists)







not tested too much so far, but everything I’ve seen looks much better. The only ‘bad’ colours I can see now are where there should be shadow sprites / alpha blending effects.

Emu WIP CPS3 Mame WIP, Full-screen Zoom

I’ve come up with a preliminary implementation of Full-screen zoom, used pretty heavily by JoJo and Warzard.

Right now the code assumes that the view will never be zoomed more than twice the normal visible area away, as it’s a framebuffer zoom I’d expect there to be some sensible limit in hardware such as this, although testing on the real hardware would be good.










Test source code can be found at http://haze.mameworld.info/misc/cps3_220607_fsz.zip Again I’m not posting binaries.

Note, I haven’t managed to fix the reported crash in SFIII NG, I’m looking into it now.

Emulator WinUAE 1.4.3 Public Beta 6

system PC - Windows

Amiga emu, news:
* rar unpacking double memory deallocation (unrar.dll is still the most stupidly designed unpacking library)
* crash if dearchiver (rar or archiveaccess) was not available
* hardfile filesys loader/relocator sometimes incorrectly allocated code/data space from chip memory
* lha/lzh archive detection fixed
* P96 ram allocation forced indirect JIT mode
* -datapath fixed, overrides paths-panel paths again
* recursive harddrive archive support enabled

Archives inside archive are only unpacked when first accessed for best performance. Tested by creating 200MB zip archive that contained ~250 pre-installed zipped WHDLoad demo slaves. (Note that this can confuse some programs because size of "harddrive" gets bigger and bigger the more archives inside archives are unpacked..)

Original archive is "duplicated" as a directory called <name of archive>.DIR

"file not found" or "empty directory" is returned if decompression fails

In future there may be options to disable recursive archive support and ability to replace original archive file with unpacked directory (without .DIR extension) Another future idea is write access (to separate "diff" directory)

Note: rar archive inside another archive can not be unpacked without archiveaccess.dll (unrar.dll can't do it without temp files and I refuse to use temp files)

system PC - Windows/dos, S60 3'rd edition phones

Nes emu, news:
This version adds proper emulation for non-standard input devices: the light gun (Duck Hunt, etc), the paddle (Arkanoid) and the PowerPad (Athletic World, etc).
First two are simulated with a mouse. The PowerPad uses the left and right sides of your computer keyboard. I have also extended the built-in menu with options to choose new input devices, record game soundtrack, and swap DiskSystem floppies. To save screen estate, the built-in menu has been rehashed. It now has universal "Load File" and "Save File" options and figures file type by its content.

The iNES-Symbian has got a lot of new Symbian-specific features. You can now configure its display for portrait or landscape mode and force display backlight on (this should work around the backlight bug in the E62 firmware). Starting with this version, iNES-Symbian supports FamiBASIC keyboard and provides a virtual keyboard ([EDIT] key) for phones without the real keyboard. There are a few fixes that prevent possible crashes, warning messages, and so on. Finally, I have fixed the opendir() bug, so all built-in menu options work now.

homebrew Toad's tool 0.3b

system PC - Windows, Mac OSX

Mario 64 editor util, news:

•A bad bug in Windows that was triggered when right-clicking causing TT64 to crash or refresh the window was eliminated.
•Some imported textures weren't correctly saved to ROM (creating a dot in the corner). This should now be fixed.
•The "Rotate Camera" button should now be hilighted as it should, when a level is loaded.
•Manually entering decimal values in the parameter bar would cause the wrong number to be entered instead. Also fixed.
•On Windows TT64 should now stop using CPU cycles when it's window is deactivated or minimized.
•Fixed a bug where clicking on cancel when opening a ROM would generate a script error.

Some people seem to have problems opening a ROM even if it was extended, for example generating a script error while loading in TT64. I guess that there are some variations in the ROM versions, and that even if the ROM extender works on a ROM, it doesn't guarantee that it will be compatible with TT64. In future versions I'll implement a more thorough check to ensure people open/extend the right version.

Bad news: it seems that levels that I thought would be very reconfigurable, (Bowser courses, Lethal Lava Land) actually are limited by the fact that they rely on the main level collision data. If you move platforms in these levels, the collision data won't move with it. Dealing with this will require some pretty complicated collision data editor. I guess that this problem will encourage me to work on it sooner than expected. But don't expect miracles, it's not as simple as enabling movement of individual vertices in the collision data.

The Documentation is still not finished, but I made a few changes (mainly the styles and layout).

I'm gonna leave town for 6 days starting Monday, instead of Sunday. But, I'm also gonna be outta town later today, and be back by Sunday afternoon/evening

mame fer PalmOS things like the Zodiac, news:
* Wow. Well I decided it was time to upgrade. So this is almost half-way to my goal of updating to the base MAME 0.37b16
* So all new working original games from 0.37b1 to 0.37b6 are supported unless they had known problems in which case they are disabled.
* This makes the file sizes significantly larger as there are updated cpu cores, some new ones and a ton of games.
* Hacked the CAVE games (Dangun Feveron, Esp Ra. De. and DoDonPachi) to work with palms limited memory. You must turn off the sound to make these games work and (you might want to sit down) YOU WILL NEED AT LEAST 60MEGS of free RAM to play them. They work pretty well on the Zodiac though, quite playable.
* Speedups will be added once the code base is stable again. Anyone wanting to help optimize the speed should contact me! Although nothing will be done until I hit the highest MAME version before the speed drops off.
* Artwork has been updated to support later versions of backgrounds.
* High scores now save and load properly (need a hiscore.dat in your palmmame dir)
* Smash TV and Total Carnage now work!

Emu WIP CPS3 Tile Compression Part 3

Sean's Stage in SFIII New Generation uses a different compression scheme to the other games. For some reason, Capcom decided that one stage, in one game would use a different system. The Compression used on this level supports 8bpp tiles instead of 6, thus allowing for more colours, but a less efficient compression scheme. I’ve spent some time looking at this, and mostly figured out how it works. There are still a few problems, but I now have reocgnizable background tiles at least.

emulator Daedalus PSP R12

N64 emu, news:
[!] Fixed issue preventing Goldeneye from being loaded.
[!] Fixed dynarec for Goldeneye.
[!] Fixed dynarec for Super Smash Bros.
[!] Fix various texturing issues with 4bpp and small or non power-of-2 textures.
[!] Fix TexRect instructions with negative s/t components.
[!] Fixed the HUD in Mario 64 (broken in R11.)
[!] Fixed lights in F3DEX2 microcodes.
[+] Correctly implement instruction fetch exceptions, improving compatibility.
[+] Improved floating point compatibility.
[+] Correctly handle mask_s/mask_t tile values.
[+] Implemented a few custom blend modes.
[+] Screenshots just cover visible viewport.

If you've been following the updates on this blog over the past month the most obvious change is that Super Smash Bros. is now running well with dynarec enabled, and many graphical glitches have now been resolved. The compatibility fixes were specifically aimed at Super Smash Bros. but may well fix issues with other roms too. Overall SSB is looking and playing much better than it was in R11, but even at 30-40fps it's still not running at fullspeed yet. There are a few graphical issues that still need resolving, but all in all it's starting to feel very playable with frameskip set to 1 or 2.

Goldeneye is also running in R12. Although the intro sequence is running very quickly and with few noticable graphical issues, a lot more work is needed to it running at a playable framerate in-game. I think it's a good start though, and something to get excited about for the future

Otherwise R12 just has a few minor compatibility and graphical fixes - there are no optimisations for this build.

PC-Engine emu, news:
**IMPORTANT please read
In almost all the games of TurboGrafx16's "Turbo-Chip", there is a report that is able to play without trouble with Ootake. Please convert it into a correct image file if you use the sucking out machine for Japanese "Hu-Card". It is possible to convert it when the file is opened with Ootake. The converted "just proper" image file can be used with [a lot of other Free TG16/PCE emulators], too. This is a "fair" method for the "PC Engine & TurboGrafx16" emulator and the PCE/TG16's fan. (Thank you for reading.) Video chip (VDC,VCE) processing part was considerably sped up. I think that processing lightened in some measure of a personal computer environment so not fast.
# The screen processing of "SUPER GRAFX (Japan)" was improved, and the speed improved.
# Processing related to the "ARCADE Card (mass buffer memory card of Japan)" is improved, and interchangeability has been improved. "Laplace no Ma" came to operate without trouble.
# "ARCADE Card" menu was added to "CD-ROM" menu. If this check is removed, it can be operated in the state of "ARCADE Card none".
# "Star Mobile" came to operate.
# Operation speed & timing of CPU has been elaborately adjusted. In stage 3 of "Soldier Blade", the screen disorder of one frame (generated by v1.10) was solved.
# In visual scene of "Ninja Ryuukenden", overlapping the screen was corrected.
# Additionally, a detailed part has been improved and corrected.

system PC - Windows

does exactly what it says on the tin, news:
New features emulated:
# Palette fadein/out
# Sean stage special tile compression
# Proper sprite/tilemap alignment
# Proper priority handling

The CPS3 emulation is almost complete. Only the shadow/blending emulation is missing. There is a preliminary emulation for it that works partially with the shadows, but is not correct in some other places (warzard sword effects for example).
I've added savestates support. To make a savestate, first select the slot with CTRL+number (in the main keyboard, not in the keypad) then press F11 twice (it's done that way so you don't accidentally delete a working state). To load a savestate, select the slot and then press F10.

I've added an option to set a custom fullscreen resolution in the .ini file (FullScreenWidth,FullScreenHeight). You must enable it setting Video->Fullscreen Resolution->Custom. Using a resolution that is not supported by your video card will cause the emulator to crash.

I'm not including the MultiCPU version as it causes some graphics glitches and if you have a dual core CPU, then you have enough power to run the standard version.
