Yes you need the BIOS file. It's not included as the file is under copyright. Search Google for "neogeo.zip" and place it in the emulator's ROMS directory.Ok Im trying to get the neo geo emu working on my fat psp cfw 3.90 m33-3. I have downloaded the MVSPSP file from here and I also created a cache folder for the games I want to play. The problem is when I start up the emulator on my psp and go to roms and try to play the game, it goes thru the cache process but then I get a "BIOS not found" message. Was there a Bios file that was supposed to be included, because I don't have 1. Thanks for the help!
I got the very same error but with MAME, i have DL it from various places and various versions of it and nothing, it keeps failing. I have a psp slim with 4.01 M33-2.Ok I downloaded the CPS1 emulator from this site (cheeseballs) When I downloaded it I got 2 readme files and 1 "cps1psp" file. Inside the cps1psp file I have these files: eboot.pbp, rominfo.cps1, zipname.cps1, zipnamej.cps1. I tried putting the cps1psp file into Game, game 150, and game 380 files, but I got a error message 80020148. I tried going into recovery mode and changing the Kernel from 3.90 to 1.50 and tried putting the file into all 3 game folders ,but same result. Any suggestions would be greatly appreciated!
