>By the way, I just click on Quick Start. It keeps saying like that "Cannot find matching Game ID!".
ePSXe doesn't have a 'Quick Start' option IIRC. It has the first start Wizard to select the BIOS and plugins and to configure the pad, but it doesn't have a 'quick start'. Futhermore, you should really tell us the name(s) of the game(s) you are trying to play, not to mention the Operating System you are using... system RAM and Graphics card shouldn't be to hard to establish either.... the BIOS file you are trying to use, the GPU/SPU/CDR plugin you are using, etc.
Forgive me for being rude, but you don't just go to a garage with a broken car and say 'it won't start; fix it'.
