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" whic...

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.

Re: Downtime, and forum software updated to version 3.2

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.

I'm glad everything went smoothly. Thanks for keeping the site running.

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. I'll leave finding out the details to your demonstrated development skills ;) - ensure you have cdrtools (or wodim in Linux) on your (KOS-based) development system. - note that the loader tool...

Hi. If I understand you correctly, you have successfully burned a bootable multisession dreamcast disc of your game and want to distribute a BIN+CUE so that generic writing software can burn it? imgburn just worked for me as you described so you could just be missing a step somewhere. I burned a dis...

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...

Re: Freeing Texture problem?

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...

Re: Undefined references to C++ functions (stdc++)

It seems you are using CMake instead of the standard make for your project and rewriting the compile flags... Does it matter for your project that you don't have the -nodefaultlibs -nostdlib -nostartfiles flags? I also just noticed that in the environ_base.sh kos is set to compile (itself?) with -st...

Re: Undefined references to C++ functions (stdc++)

Once when I experienced similar issues using a successfully compiled tool chain, it turned out to be related to the binutils used during compilation. There just seemed to be a discrepancy between what gcc and binutils wanted as far as directory structure goes. I don't know if this is the issue you h...

Re: Is it possible to make std::future work?

Jut something I noticed about tas.b: Even though it only tests a single byte, the CPU locks and flushes the entire cache line (32 bytes) so if there was a concern about not being able to atomically read/write larger sizes, you could use this information.

That's amazing! Do you have some formal training in electronic repair?

I used one of those (maybe not the exact model) long ago, but I d...
