there is no mame port for the gp32 if thats what your asking. As for xcade I could be wrong but I don't think that acctually uses the same roms that are used for mame.
There is no full MAME emulator. Some old arcade games can be played with XCade. Some of the roms I use with MAME worked with XCade, for others I had to find extra files but that's not hard to do
