I've got a EFA 256Mbit card with a MK2 and I can't get it to work. I can run other homebrew-stuff, but when I try to start this, I get a white screen. I've tried to use the loader you guys recommended and the one that comes with my EFA 256Mbit card, but without success. So, got any ideas? Or should I try to get a SD-memory for my MK2?
