Hacking Decrypt & re-encrypt saves for "most" games (sort of)

[cearp]

cearp whats your FC code bud. I wanted to PM you but for some reason I cant send you a personal PM. PM me and let me know your FC code and I will add you asap. add both of mine or just the XL if you want. Please let me know soon as you get this message.

can't send me a pm... hmm i'll check that out, maybe something i did (not on purpose) i don't have my fc copied anywhere, so i'll need to check my 3ds, but i haven't been playing much recently, been way too busy, but still, i'll let you know

PM the code when you get it. We don't have to be in touch with each other playing all the time online but if I have it on and your online on say MK7 the same time as me I can join you, its handy. Also I can send you some funny stuff on the letter app

Oh, I see how this works. It's essentially a rom hack that modifies the header and tells the 3DS to use an older save method, so when it saves, it saves in a way we can decrypt. In theory, couldn't one use this method, with both a decrypted save and an encrypted original version, XOR them together (Or even just a small portion of the file) and get the decryption keys for the newer games so someone can decrypt their game's save without having to do this?

Not sure, as I'm not that savvy. However, I think the only way that would work is if both the encrypted original and decrypted new save had the exact same game progress.
