Adventus ported ZDoom to GP2x, ZDoom is an enhanced port of the official DOOM source code.

Changes:

– I have implemented an SDL sound renderer. So sound and music should be supported in all games.
– There are some strange graphical glitches (a few flickering walls, nasty menu text, etc). However it is very playable in its current state. I will look to improve this.
– So far I’ve tested the Strife, Doom 1, Hexen & Heretic demos. Its up to you guys to test the rest. I suspect some of the more complicated mods might not be playable.
– Don’t forget to read 2xZdoom220.txt and go to the “customize controls” menu to set the controls for each game.
