i had an n3ds and played a lot of luigis mansion. i backed up my save with the backup manager in the settings app. i kept the 000 folder it made and tried to transfer it to the new 2ds xl. first i created a new save and backed it up the same way. then i copied the old save and overwrote the new save. it didnt work. my original save was created from a legit cia and the new one is from freeshop. my save comes up corrupt. recently, i found checkpoint and tried playing with that. no luck. how can i get my old 0000000.sav to work on the new console?
