I've been a lurker around here many times, but this is the first time I've needed to post. I've got a legit R4 that's almost two years old and I'm using a 2 gig SD card. Recently it's been acting a little strangely. Namely saving isn't working correctly. The biggest problem is with Knights in the Nightmare because it just won't seem to hold a save. I had the latest R4 firmware, which admittedly is ancient, and then switched to YSMenu. The game won't save in either. I thought maybe it was a bad rom, but I've tried a few different ones with no luck. So do you guys have any ideas about what could be causing the problem?
