If you are going to opt for 4x memory card, I would say perhaps avoid the official SEGA model and go for a 3rd party version that is more reliable like Nyko brand. Not only is the former a bit more expensive, but a few key titles are not compatible with it (ie: Dynamite Cop crashes, Spawn ITDH will not recognize it, and so on). These issues do not occur with most 3rd party 4x memory cards... Thanks again guys, and I'm going to look into a x4 card too so I can save some other games
Enjoy you DC!
