WinXP 64bit???...are you serious, terribly supported OS, get Windows 7, and yes you do have to have a 64bit OS to benefit from a 64bit compile of MAME.

Those Cave games are no longer supported in MAME due to a take-down request by CAVE, so don't ask about them here, you'll get your wrists slapped.
