How to play neogeo games on your PSP FAT

1. Download the MVSPSP v2.3.1 (PSP Fat) emulator: http://www.gamergen.com/telecharger/mvspsp-v2-3-1-psp-fat-52301

2. Unarchive and upload it into your PSP: /PSP/GAME/mvspsp

3. Find a correct neogeo.zip file on the internet, then upload it into: /PSP/GAME/mvspsp/roms

4. Upload .zip games roms into: /PSP/GAME/mvspsp/roms

Generate cache files

Some games must be pre-processed with the romcnv tool. If you are on windows, use the romcnv_mvs.exe executable provided. If you are on linux, you have to compile it yourself.

And if you are on a mac, you can use a docker container:

1. Install docker

2. Put your games roms into ~/neogeo

3. Fetch emulator sources

    $ cd ~
    $ git clone [email protected]:phoe-nix/NJEMU.git
   

4. Launch a temporary docker instance in interactive mode

    $ docker run --rm -it -v ~/NJEMU/romcnv:/root/romcnv -v ~/neogeo:/root/neogeo -w /root/romcnv debian:jessie bash
   

5. [inside container] Setup build tools

    $ apt-get update && apt-get install -y --no-install-recommends make automake gcc build-essential g++ cpp libc6-dev man-db autoconf pkg-config
   

6. [inside container] Build the romcnv tool

    $ make -f makefile.mvs UNIX=1
   

7. [inside container] Convert games roms

    $ ./romcnv_mvs ~/neogeo -all
   

8. [inside container] Move cache files to your mac filesystem

    $ mv cache ~/neogeo
   

9. [inside container] Exit and delete the docker container

    $ exit
   

10. Now you can upload files that are in ~/neogeo/cache into your PSP: /PSP/GAME/mvspsp/cache/

11. Enjoy
