* To install the MVSPSP, you need to copy the MVSPSP folder into the GAME folder so that you can proceed to run the program in 1.50 kernel. If you can secure some roms for yourself, look for the other folder dubbed romcnv. The romcnv folder has an exe inside that can change your roms into a cache file. This cache file is necessary (just like the roms zip file) for use on the PSP.
* After that, you have to create one folder labelled CACHE within the MVSPSP folder.
* Once done, set it in the ROMS folder. You don't need to create a cache of that info though.
