Re: iOQuake3 Dreamcast port?

Seriously though, when are you going to implement SD support for VC/DC? I don't have an SD card adapter, so I couldn't test it, and I'm working on other things at the moment so I don't have a release planned anytime soon. For the other media formats you mentioned, something like xine or ffmpeg woul...

Re: iOQuake3 Dreamcast port?

1) From who? Even the best rumours about DCiberia's magical SD card put it at way slower than any ram. Then there is the fact that releasing something that requires the SD card in order to work is going to severly limit the number of people who will be able to use your program. My opinion is that i...

Re: iOQuake3 Dreamcast port?

OneThirty8 has recently implemented a PVR renderer into a simpler 3d engine, maybe he has some input on this subject... Yeti3D was originally designed to run on a GBA and writing the PVR renderer was really simple after BlackAura posted information on how to use paletted textures. I wouldn't know w...

Re: Yeti3D demo with PVR rendering.

I uploaded a new version of the demo level with md2 models in place of the sprites. It looks like there's a bug or two that I need to hunt down, but I wanted to post something for people who can't download the source from SVN and compile it. http://yeti3d-pvr.googlecode.com

Re: Yeti3D demo with PVR rendering.

I don't know of any sites dedicated to Yeti3D. It's a very easy engine to work with, but I don't think it has been used much. I have a very old and crappy tools package on my site at http://www.storm-studios.net/onethirty8/YetiStuff.html that includes a map editor. The tools I wrote are kind of emba...

Probably of interest mainly to developers, if there are any interested in using Yeti3D... I'm working now on getting md2 models working properly now, based on the code that Derek J. Evans provided. I have to write PVR rendering code and make the loading of everything a bit prettier, but the SDL vers...

Re: ADPCM

I would go with Ogg like the others said, but if you want to use ADPCM for background music, you could just make a modified version of kos/kernel/arch/dreamcast/sound/snd_stream.c to do the job. It wouldn't be hard at all--the biggest things to change would be in: int snd_stream_poll(snd_stream_hnd_...

Re: Universal Hint System (UHS) app?

The only UHS readers that I can find doing a quick google search include the official (proprietary) one, and OpenUHS which is written in Java. It's not inconceivable that such a thing could be written for the Dreamcast, but it would be helpful if there was one already written in C or C++, and then s...

You could use rotation for a cheap isometric effect.
I thought Mappy already gave you the ability to load an isometric map. Am I thinking of something else?

Yeti3D demo with PVR rendering.

I've been working on a PVR-accelerated port of Yeti3D. The only download I have is the demo by Derek J. Evans, and it still has some glitches but I thought I'd share. It's based loosely on the OpenGL example that was in the source archive I downloaded way back when, plus I also took the time to figu...

Re: Trying to make a Dreamcast Mappy playback library

Thanks guys. I understand what OneThirty8 is saying but BlackAura I am confused. He basically said the same thing I said, except that clipping is not necessary. But he gave you an efficient means of doing it, whereas I did not. So what you basically want to do is just get the total height in tiles ...

Re: Trying to make a Dreamcast Mappy playback library

I think you need to do better clipping than you do with the SDL code. I'm experiencing something similar with some 3D code I'm working on. Basically, what is happening is you have some overdraw beyond the edge of your clipping window while scrolling. Also, test for maphclip and mapvclip to see if th...

Re: Trying to make a Dreamcast Mappy playback library

You could speed it up a bit by making the header only compile into a context if the values change. I am having trouble with this. It makes a lot of sense not to compile the header again if you are going to use the same texture which is A LOT in Maps. I wrote something like this: Private Members of ...

Re: VC/DC 0.2 released.

There are 3 ways to encode Aspect Ratio: Pixel 1:1, WS 16:9, and FS 4:3. Pixel 1:1 ratio ends up streched to an innacurate AR. Pixel 1:1 ratio probably is inaccurate, now that I think about it. If I recall correctly, I had the player check for 16:9 and default to 4:3 otherwise. WS 16:9 does indeed ...

Re: Paletted Textures

What is an "alpha-only texture"? In the example BlackAura gave, he suggested a palette you could build like this: void somefunc() { int i; for (i = 0; i < 256; i++) { pvr_set_pal_entry(0, PACK_ARGB8888(i, 255, 255, 255)); } } A texture using that palette would have all white pixels, but depending o...
