hey, I'm having trouble getting psx rom working. I can load certain games ie) blades of steel but I can't the the hockey players on the ice, just a black screen with numbers skating around. It also flashes saying no bios found at the beginning of the loading the game(s). Some are img, ccd, or bin extensions. I was just dropping them into the psx folder. Is there something else I have to do with the bios? thanks
