Hmm I'm having a problem with the Quake2.wad file. I've tried both .02 and .04 versions of Doom to try and play it by putting it in the wad directory so that the path looks like K:/PSP/GAME/DOOM-PSP/WAD/DOOM2.WAD with doom2.wad being the renamed QUAKE2.WAD. Every time I try to start it from the memory stick menu it gives the 'Game could not start 80112etc' error. Any ideas on what I'm doing wrong?
