Was not sure where to post my Question. Hopefully this is the right spot. Here goes. I have been reading that the MAME Team has cracked the encryption and have been hearing all these Arcade Emulators talk about all the CPS3 roms that the systems can play.  Does any know if I can play Marvel vs Capcom 2, what emulator i would need if it is out and working?
