What MVSPSP is

MVSPSP is a free emulator for Neo-Geo MVS and AES systems, built to run on PSP. Its public repository displays a GPL-3.0 license. The project includes modified builds described as compatible with HBL; the README explains that these builds omit loading the systembuttons.prx file and its button functions. The maker identifies the modified versions as based on emulator versions 2.2.1 and 2.3.1.

A game cache must be created before use. The README says some files used to create the cache can be removed from the ZIP afterward. Version 2.2.0 added ROM sets supported through MAME 0.119 and bootleg sets supported by MAME Plus!. The Makefile enables save states, AdHoc play, and a command list. Other build options include Japanese UI and 32-bit UI drawing. AdHoc play requires KERNEL_MODE, while the README recommends turning off 32-bit UI drawing outside NCDZPSP to reduce memory use. A PSP-2000 can use expanded memory when the build uses the PSP_SLIM flag, but still needs a cache. The listed build environment is Cygwin and PSPSDK revision 2318. The README is signed by Herz.

Who it suits

MVSPSP suits PSP owners looking for Neo-Geo MVS or AES emulation, including people using modified HBL-compatible builds. It may also suit users who can create the required game cache and build with the documented PSP development environment.

What it does well

  • Free to use, with a public GPL-3.0 repository.
  • Emulates both Neo-Geo MVS and AES systems.
  • Modified builds are described as HBL-compatible.
  • The Makefile enables save states and AdHoc play.
  • PSP-2000 expanded memory is available with PSP_SLIM builds.

What to know first

  • Requires creating a game cache before use.
  • AdHoc play requires KERNEL_MODE in the build.
  • Build instructions list Cygwin and PSPSDK revision 2318.

Limits

MVSPSP requires a game cache. AdHoc play can be compiled only with KERNEL_MODE enabled; PSP-2000 expanded memory requires PSP_SLIM and still requires the cache.

Getting started

  1. Open the MVSPSP project repository.
  2. Prepare the listed Cygwin and PSPSDK revision 2318 build environment if building from source.
  3. Choose the PSP build options needed, including KERNEL_MODE if compiling AdHoc play.
  4. Create the required game cache.
  5. Use a modified build described as HBL-compatible if HBL compatibility is needed.

Verdict

Choose MVSPSP if you want a free PSP emulator for Neo-Geo MVS and AES and can prepare its game cache. Its PSP build requirements and cache setup make it a less direct fit for someone seeking an emulator on another platform or a ready-to-use setup.
