Well I managed to fix MAME and find the other emus mentioned above.
Had to fix them to like which then made me realise that PSP is really fussy about file structure!
So ive tested a few games on each system, MAME is pretty bad, A few playable games but yeah quite terrible :p
The CPS and MVS ones I have tryed so far play ok but not all working, I am assuming thats my roms as opposed to the emu though.
Do you know if there are any dat files or anything to rebuild roms for these emu's B2K24?
EDIT: Just realised there is a rom convertor in the pack! Doh LOL
99% working now
