Davex has released his unofficial edited version of NJ’s Neo Geo MVS (SNK) arcade emulator. The emulator runs smoothly and with out issue allowing for full enjoyment of your favorite neogeo games with out lag or skipping.
To successfully use this emulator you will need to extract the mvspsp directory to your psp’s game directory and extract romcnv to your desktop this contains a tool you will need to generate cache files of your MVS roms. Once you have generated a cache file from the zipped rom you will need to copy the generated cache game directory into the cache directory with in the emulators directory and then copy the rom into the rom directory. You must have a cache and rom file in almost all cases. The BIOS files have been included for this emulator as well, I would however recommend using MAME4ALL over this emulator if you can get it working properly on your CFW(Custom Firm Ware) as it does not require these steps.
