Re: The Dreamcast turns 21 today!

Happy Birthday Dreamcast! I have a lot fond memories and I will be playing it more frequently from now on. I really enjoyed watching video reviews and then seeing the games match what was shown. I've oiled my gd-rom so it's much quieter, but I still love hearing the drive squeak when it accepts a di...

Re: High Resolution Dreamcast Video Modes!

I just wanted to post a better picture. The 1152x864 and 800x600 rendered correctly whereas the others I tried were just garbled like before. I gave up on trying to figure out the stretching/squishing algorithm because just writing pixels to the screen is a huge task for me. Not bad looking for a 40...

Re: High Resolution Dreamcast Video Modes!

That definitely doesn’t look right, though. It should look right if you multiply the horizontal axis of the image by the horizontal scale in the file (STARTUP_video_params.video_scale_multiplier holds that float), and then copy the image directly from RAM to the framebuffer. That’s the first test; ...

Re: High Resolution Dreamcast Video Modes!

Exciting stuff! I went back and read the readme which was definitely easier to integrate than the way I had hacked it. The modes output correctly (I tried 800x600, 1024x768 and 720p) but I've been having trouble rendering using the pvr 3d pipeline because I'm not informed on the detailed workings of...

Re: High Resolution Dreamcast Video Modes!

BRILLIANT! Thanks. It always wondered why we couldn't output higher resolutions even though the GPU was based on a pc chip. So, you're saying that the 3D and 2D pipeline would be working optimally with a lower resolution but the ramdac would upscale the image? Maybe a photograph would help demonstra...

Re: Anybody available to help with dc-load-ip testing?

It's great that you are excited to get this working. Personally, I don't think re-dialing would be a big issue since the videos show it taking less than 5 seconds... I'd love to read your guides on Dreamcast gdb-over-bba though, just to get the hang of cross-platform debugging. I suppose I've never ...

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.

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.
