Set to 22kHz if you experience minor audio stuttering on massive games, though 44kHz runs perfectly on 95% of the library. Control Mapping
remains the definitive homebrew emulator for playing Neo Geo arcade games on the Sony PSP. Despite its age, this version is celebrated for high compatibility, supporting classics like Metal Slug , King of Fighters , and Samurai Shodown on both PSP-1000/2000/3000 and the PSP Go. Key Features of MVSPSP 2.3.5
Standard MVS/AES arcade ROMs are too large to load directly into the PSP’s limited RAM. MVSPSP solves this by reading a cache file generated by a desktop tool called romcnv . Open the romcnv folder on your desktop computer.
Copy the generated cache files into the cache folder located at PSP\GAME\MVS\cache\ . mvspsp 2.3.5
is a specialized Neo Geo homebrew emulator designed for the PlayStation Portable (PSP). It is part of the "UO" (User Only) family of emulators, which are community-driven modifications of original source code—most notably the work of developer NJ—optimized to run high-performance arcade games on the PSP’s limited hardware. Technical Background and Hardware Support
Extract the folder on your computer. Inside, you will typically find folder variants like mvspsp and mvspsp_slim . Step 2: Transfer to PSP Connect your PSP to your computer via USB mode.
The “MVS” in its name refers to the Neo·Geo’s arcade hardware. Unlike later emulators that rely on heavy filtering or dynamic recompilation, MVSPSP uses a mix of C and assembly optimizations to leverage the PSP’s two MIPS R4000 cores (though the PSP’s architecture is complex, only one core is typically used for CPU-intensive tasks). Set to 22kHz if you experience minor audio
For 98% of Neo·Geo library, the game runs at full speed with no frameskip needed. The remaining 2% (mostly late-life SNK games like Matrimelee ) may experience minor slowdown during multi-sprite scenes.
Unlike many emulators of its era, MVSPSP 2.3.5 fully supported the (universe BIOS included). You could switch between MVS (arcade) and AES (home console) modes, enabling blood in Mortal Kombat or disabling the “insert coin” screen for a home-like experience.
Create a folder: /PSP/GAME/MVSPSP/roms/ Place your Neo·Geo ROMs (in .zip format) inside. For compatibility, ensure they are from the or Final Burn Alpha sets. MVSPSP 2.3.5 uses a specific cache system—larger games ( Garou , KOF 2002 ) will generate .cache files on first run. Key Features of MVSPSP 2
