Last stuff I saw about the topic was over a year old... and at the time, Mario Kart 7 saves still couldn't be decrypted. Is this still the case? It's hard to believe that nobody has worked on it at all in a year, especially now that MK7 is available in the eShop. I actually just ran into a weird problem, which I am not sure how to fix. A friend of mine sent me his physical copy of MK7 (I got rid of mine when I got it as a download) - he had completed it 100% and had a ton of coins... what I was going to do was backup the save file using the R4i Save Dongle, use the physical to download program that Nintendo FINALLY put out, then restore his save so we're both happy. But apparently as a result of the save dumper freezing up on me, it screwed up the save file. It says it's corrupted, I've tried restoring it a few times and still get that message. So now I fear there is no way to get his game back without starting from scratch... unless somebody has decrypted those saves, in which case I can just use one off games-engine.
