I would like to transfer a save file from a digital copy of a game on my old 3DSXL to the Gateway 3DS rom on my new 3DSXL. First off... is this possible? For example on my old 3DS I have Luigi's Mansion Dark Moon. I used the stock "Backup Save" option. I then took the SD Card and put it into my computer and copied the 00001.sav file created in the "Nintendo 3DS/UserID/backup/TitleID" folder. I renamed the 00001.sav to the 0004000000055F00.sav That is the proper title ID for the game. I then pasted this on the SD Card alongside the Launcher.dat with the other .sav files created by Gateway 3DS. When I launched the game it said "Save file is corrupted. Deleting Save file". Is there any way to do this correctly?
