Ok did that. Forgot about the reset button, thanks! Still though, when it starts, I get "Please Wait..." then that screen goes away to a blank screen. If I hit Select+Start at the same time, I get the emulator menu ("Continue, GameConfig, KeyConfig, State Load/Save, Reset, Exit), but the ROM never loads. I've checked and made sure the ROMS weren't on the list of ROMs that don't work. And this seems to happen with every CPS2 ROM I try. Maybe I got a bunch of bad ROMs? What's the correct file size for the AVP ROM I should be using?
Nevermind again! That was it! Bad ROM files. Found good ones.
