I have an M3DS Real, and a DS Lite. It was working fine, I upgraded to the latest firmware, Sakura 1.47 or something, and I can navigate and start new games, but if I have an existing save for a game the game refuses to load, the bottom screen says "Data format error." Any ideas?
(I have my saves backed up from before upgrading, so I didn't lose everything)
