Sherpya has released a new version of the port of Heretic for the PSP, heres whats new:
Update, sound support added is not very smooth, but not so bad (I think I'll need to implement a sort of noise shaper since samples are 11khz 8bit),
also a bit faster since I've enabled -O3 on the compiler (before was crashing with opt > 01 since there is an incompatible gcc optimization)
