I have a brand new Supercard+Superkey and with the newer games (Castlevania and Kirby) I get corrupt saved data loop even tho I havent tried to play the game before that time. Anyone know what I need to do to fix it?
I also just recieved my supercard an superkey 2 days ago. I was having these issues and found that even though I downloaded the newest bios from the supercard site (1.70), it was to blame. Try the firmware from here. It worked for me.
