Hi, Acaturbo. I've tried Ehrgeiz with VGS in the past and it played ok. I tried it just now with ePSXe, and it run very well (I played the arcade mode). I used Pete's OGL plugin for graphics, Pete's CDR plugin for cd-rom, and the internal plugin for sound. My bios is the scph1001 one. I didn't use any special settings, like accuratre cd-rom timing or F4.
