notes: extract and put MVSPSP folder to PSP/GAME (with 1 rom and a very large cache file, KOF2003)
if you are encountering problems while running a certain rom convert it first. run mvsconv_slim_all.bat under rom converter folder/romcnv, and then choose your rom (.zip) with issues...
after successful conversion, it creates a CACHE folder... put the CACHE folder to PSP/GAME/MVSPSP... if it still has issues, there's a problem with your rom...
