Image provided by: gp32x.comPrBoom is a cross-platform version of the classic 3D first person shooter Doom from id Software. Originally written for PC, PrBoom has been lightly modified to run on GP2X. Release notes:

With the help of theoddbot, DJWillis, Woogal, and Nickspoon, I’ve made a (quick) port of PrBoom for GP2X. As always, this first release is a beta. Everything sould work. I didn’t put any sync code in the game itself but the provided launch script call sync at game exit. I didn’t test any dehacked or additional WADs, but everything that works with (Pr)Boom/MBF and does not requires hight-res or OpenGL should work on the GP2X.
