Neither of them are playing too good , the NFL 2K2 Intro is slow and freezes up etc.
Also My Edited GDI Creation I tried doing for RESIDENT EVIL 2 Simply turns on a Black Screen that one I was expecting

At the moment just using the 2GB Card I have , I did order 8GB perhaps that will help some how ?
BTW I got JAPAN Dreamcast , Not sure if that makes a difference lol.
