Steknos

Hi, I'm trying to use my NEW modded xbox to emulate my old Playstation games. I'm using PCSX XBOX, but it doesn't seem to work. I tried to run "Street fighter Alpha 3" and "Tekken 2", both original copies. With Tekken 2 the emulator is able to recognize the cd but gets blocked when I try to run the game. With Street Fighter Alpha 3 (one of my favourite games ever!!) pcsx doesn't even recognize the Cd. I insert it, go to Select Game, then into R:\UDF DVD-ROM, but nothing is displayed. I tried to insert the Cd in my pc and everything seems ok, it's not an empty Cd (and of course it works on my old Playstation) I read that someone here had problems with Dramatic Battle, so I guess somoene can help me....at least I hope ByEz!
