Not unless you want too.Huh wow so if I have an X2, there's no reason at all to buy an x3, fast IO, or RFID?Yep all games will be fully playable. Even USF4, with all 3 builds of the same version 1.05 without patching.The multi and all games will work with either JVS or FastIO. The I/O is all 100% seamless. If you have a JVS I/O connected then the multi emulates RFID and converts JVS to FastIO automagically. If you have just a FastIO connected then the multi emulates the RFID reader and only converts FastIO to JVS for the JVS only games. If you connect an RFID reader then the multi lets the games talk directly to the card reader. If you have nothing connected to your X2, and your X2 is really just a box of Captain Crunch then the multi probably wont work.So will the new multi work on the x2 with all games playable? USF4? I just want to be prepared for when it is released. Will it work with JVS or will FastIO be needed for some games?
One thing I want to clarify, as I think there is misunderstanding. While USFIV was released as a standalone game for the X3, it was also released on Nesica.
