Re: Quake 3 lightmaps - PVR Multi-Texture

There's no multitexture on the PVR, so you'd have to do multiple rendering passes. That's what Quake 3 did on cards that didn't support multitexture, and for surfaces that needed more than two passes (some of the surfaces can have two or three layers, plus the lightmap). It's also what Quake 1 and 2...

Re: KGL- PCX from PC.

Are you sure it's not just slow? The PCX loader reads the file one byte at a time, with no buffering. KOS's filesystem is fairly simplistic, and doesn't really do any caching or buffering of it's own. Each byte that's read requires the Dreamcast to send a request to the dcload host, and then wait fo...

Re: Romdisk

Basically, it's for embedding files inside your program, so you don't have to read them off a CD. You have a bunch of files, and the build process generates a romdisk image out of them, and embeds it in the program. KOS picks that up, and makes the files accessible from /rd. You can then read them t...

Re: So I've got off the ground.

Ooookay....I thought you said transparency wouldn't work on emulators? Transparency works. Automatic depth sorting doesn't. The Dreamcast's 3D hardware will automatically depth sort transparent polygons, and draw them in order from back to front. Emulators just draw all the transparent polygons in ...

Re: So I've got off the ground.

A few possibilities. First, The z value probably doesn't do what you think it does. It's doesn't represent the distance from the viewpoint. It's actually 1 / z (because the DC does perspective correct texture mapping, so it needs 1 / z instead of z). So, smaller values are actually further away than...

Re: So I've got off the ground.

One other thing to be aware of with colour keying - you'll get colour fringing if you distort the image in any way. For example, your images use magenta as transparent. So, you set all the magenta pixels to transparent (alpha is 0). If you draw the sprite at 2x it's normal size, you'll have this mag...

Re: Drawing rgb565 image in output_buffer using PVR

The VQ format is basically: 1 - A 256-entry dictionary, with each entry containing a 4 pixels (a 2x2 pixel square) in RGB565 format. 2 - A Set of 8-bit indexes into the directory. Since you're getting a recognizable image, you've probably got the dictionary and data in the right place. If you'd miss...

Re: Drawing rgb565 image in output_buffer using PVR

Essentially, that looks about right. Two comments though: uint32 * png_dec_buffer __attribute__ ((aligned (32))); png_dec_buffer = memalign( 32, PVR_TEX_WIDTH * PVR_TEX_HEIGHT * 2 ); That first line probably doesn't do what you think. That's actually aligning the pointer itself to a 32 byte boundary...

Re: PS Jailbreak Finally Hacks PS3 (allegedly)

Once the Sony lawsuit thing is over and people are done releasing the big guns for PS3, hopefully they'll move to PSP. I have a PSP-3000 which means I have to keep my PSP in sleep mode in order for it to stay modded, which is a pain in the ass. I know some form of CFW came out soon after the keys w...

Re: Final Fantasy XIII-2 Announced!

I liked bits of FF10. The core gameplay mechanics were pretty decent. I really liked the battle system - it was functionally equivalent to that used in previous games, but completely cut out the boring bits where you're waiting for something to happen, so it was actually much quicker. No mad rushing...

Re: Working with Sound Output using the AICA SPU

PH3NOM - As far as I remember, the snd_sfx stuff in KOS is pretty basic. The .wav loader is primitive, and it's quite possible that it'd break on a perfectly valid .wav file. Specifically, it doesn't use a proper RIFF parser, so it only works if the chunks in the file happen to be in the right place...

Re: Homebrew ADX Support?

The ffmpeg wiki has a somewhat more readable description:

KOS doesn't have any libraries to decode ADX. It's certainly possible. Pretty much all homebrew just uses MP3 or Ogg Vorbis though.
