Direct Color DMA with music

Post by Chilly Willy » Wed Apr 10, 2013 5:02 am

Here's a combination of a couple of my SCD examples... my Wolf3D-ish demo for Direct Color DMA using my PCM MOD player for music. I put them together mainly to get an idea of how the music playing affected a game using DCD video. Turns out, it's not much. I don't see a difference in the speed, and everything seems okay. I corrected a bug in interpolating the texture offset across a texture boundary, otherwise, it's the same as the previous version.

Controls:
Dpad - move around
A = strafe left
C = strafe right
MODE = change music... there's 20 MODs on the CD.

The archive has all source (except the MODs), and ISOs for US, EU and JP.

Would it be possible to post a video capture on youtube, for those of us who don't own a MegaCD and are too lazy to use an emulator / can't run one while at work? :wink:

Actually "direct color mode" does not work in any emulator (except Exodus probably but i don't think it supports MegaCD yet).
