I have a backup of my .sav file for Shin megami tensei, but I didn't have the .nds file. Yesterday I decided I'd play the game again, but when I renamed my old .sav file to this new .nds file, it doesn't work anymore. The only option I have in the game is "New Game". Any suggestions? I've tried other roms, 4 to be exact, with no results. I just thought it might be because I saved the .sav last time in an EDGE v1.8, and now it's operating in v2.0 . Could that be it?
