Re: unable to find a register to spill in class 'FP0_REGS'

Please correct me if I'm wrong regarding gcc's SuperH status... I think some of these have been discussed in these forums before...

- SuperH support was dropped some time ago?
- SuperH's lack of atomic operations limits the extent to which C++11 and above can be supported?

Re: A sincere apology from Ian Micheal

Hah! I just saw your name in the programming forums and it made me smile to see you back after all this time. I've also taken a walk down my own memory lane and know there are things I wish I could have done differently. Don't feel bad. We've somehow made it this far and if there's anything I specif...

Re: KOS - static initialisation failure: __gnu_cxx::__concurrence_lock_error

That looks like an optimization by the compiler. The data is const and initialized so it can simply use the addressed value at compile time.

I think one would use extern or volatile to let the compiler know that the data is persistent.

Dreamcast is legendary! NY Times Crossword Clue!

I couldn't resist sharing. Atari is the most common gaming clue and any other clue I've encountered is usually taken from very common properties. It is great to see our beloved Dreamcast mentioned in the New York Times Crossword. The clue was pretty specific: "Dreamcast console maker" which suggests...

Re: Anyone have a way to get KOS to Compile on Mingw?

Yes, thanks for clarifying. I found myself in a mental loop wondering if I should suggest using the Linux subsystem if you weren't running Windows 10. I also haven't tried it so I also asked myself if I should try it first.

Please let us know how it goes.

Re: Wiki feedback

Coincidentally, the top of page 4 in this thread shows you encountered the same genromfs error before. Assuming you resolved that one and are now having trouble building the tools, it might help to know which stage is failing and the compiler error. I'm not using Windows so I can't be as useful as o...

Re: Wiki feedback

Getting errors in building genromfs means that you were already compiling kos. You would have had the tools already built to do this so are you getting errors rebuilding them? I personally prefer to install my dc tools in my home directory for permissions and system separation. Also, what did you me...

Re: Help turning my game into cue/bin files?

You’re welcome. I'm glad it all worked out. For the next release, could you also release an ISO of the game session so that people with loaders set up can run it from files or over a network?

All the best.

Re: Rizzo Island Game out now!

Congrats on the release. I've played the demo and it looks promising. It's nice to see an indie Dreamcast 3d platformer taking shape. I'd only suggest just a little brightness for the black/dark walls. Good work and best wishes with the development.

Phew! It still works! I've switched to the recommended dark theme, perhaps as a coincidental symbol of my embracing the important parts of my life.

Re: Help turning my game into cue/bin files?

I managed to successfully burn Dreamshell using its pre-compiled binaries and have attached the tools I used, copied from Marcus' site. It went pretty smoothly and burned at the max 24X of my drive, but I still made one toaster because the name of the Dreamshell executable has been modified in its I...

Re: Help turning my game into cue/bin files?

Oh! I forgot to mention that you need to scramble the 1ST_READ.BIN and prepend the IP.BIN to the ISO image. I've edited my previous post, but you can also use the dcload-ip sources as a reference. (make-cd/Makefile) You might burn one coaster if you miss one of the technical details e.g. forgetting ...

Following are the instructions for creating the master, just in case you are having trouble with this step.

Re: About floating point numbers and division instruction

You have got the right idea. :) r0-r3 and fr0-fr3 are always used for return values so when a function returns, the result will always be in those registers. r4-r7 and fr4-fr7 are always used for parameters so if the parameters for a function we are calling (callee) are already where they need to be...

Re: About floating point numbers and division instruction

Integer and floating point(fp) division are completely different to the cpu. The compiler uses internal functions to handle integer division because it has to be done using special step-by-step instructions/algorithms. The compiler calls a function to do this so that a large chunk of code isn't repe...

I've never understood why the Dreamcast community decided to use cdi images. They've been consistently unwieldy for me over the years, not to mention the fact that only a handful of Windows-based software seems to burn them correctly. Since you are writing a Unix/Linux guide, may I suggest you provi...
