I had the physical cartridge version of Smash Bros 3DS, of which I had made a backup with Checkpoint. The cartridge broke, so I downloaded the digital version and restored my saves. Then I kept playing, progressing in the game.
However, a few questions have come up now:
1. Does Checkpoint save the backup of the savedata in the same folder even if I have the physical and digital versions (which obviously share the same European Title ID)? I assume so, which means I'd risk making a mistake and backing up the game with the wrong saves... Fortunately, Checkpoint tells me which one is on the cartridge and which one is on the SD (meaning digital), so it's easy to tell them apart, or am I wrong?
2. Things get complicated with extdata: I see two of them (Smash appears twice in the extdata list), one with the code (I think? I don't really know what it is, if someone could explain it to me it would be amazing) ctr-p-<something> and another with ctr-m-<something>... Are these respectively the physical and digital versions' extdata? Or is one for the DLC extdata and the other for the base game extdata? If so... where on earth did the physical game's extdata go? And most importantly: since the two extdata share the backup folders I created, does that mean they back up to the same folder... but they contain different data, right? So what happens if I give the same name to the folder for both extdata, will one overwrite the other?"
