mame?

[plungmonies]

okay first, banish the thought of playing marvel vs capcom as mamepsp does not support it and probably never will in any playable form. If you really want to play it then just use the pc version of mame or final burn or kawaks.
secondly mame will display the suppoted games names, however it will be up to you to supply your own roms that correspond with those games (I know you have not yet but please dont ask where to get mame roms as most are still copyrighted however a few have been handed down by their developers to the public domain). Check out www.mame.net for more info

If you are d/l the copies from my site you should be having no problems whatsoever. They are designed for use on the 1.5. Place "MSG1~1%" and "MSG(30spaces)1" into the "PSP>GAME" folder on your MS. Place any extra roms in the "roms" folder that is in the "MSG(30spaces)1" folder. Only the roms supported by the version can (possibly) play. The few I have added to the demos all work fine.
