I get this message every time i tun on my DSL ( w/ M3 Lite in it [Slot-2 flashcart]). It saves game any and every game normally, but when I try to play that game again(after the unit has been turned off) I get that message. I dunno if its a quick fix or what I gotta do. Anyways heres the message:
"Warning! GBA GAME SAVE in card but CANNOT find AUTOSAVE backup file. Backup fail! Press A to continue."
Any ideas? Other than that, I luv the huge gba library of games :)
