So, I've had this cartridge for about 2-3 weeks and it worked fine. I've also been using Powersaves with the cartridge, and I have not encountered the main issues of save data corruption that are often spoke about. I've been cloning via pokebank for about three days now and suddenly today I ran into a bit of an issue. While restoring a saved backup, the Powersaves window changed and said "Unsupported Game." Literally 10 minutes beforehand I cloned a batch of pokes for someone without an issue (not to mention all the issue free cloning I did last night and this morining). Thinking it was just a slight hitch, I took the cartridge out of the device and reinserted it. The same message appeared. I tried putting the cartridge in my 3DS, thinking it was just a save file corruption, but the 3DS failed to even detect the cartridge. After about an hour of going back and forth, there was no luck. It was as if the cartridge was wiped clean of any data. I tried searching Google for similar issues, but only the basic Powersaves issues seem to be posted. I handle it lightly with Powersaves, and only had to hard eject it once as the progress bar wasn't moving ;however, that was either yesterday or two days ago, and the cartridge functioned just fine. I will mention that last night I accidentally ejected the cart while the game was running, but it functioned fine in the hours after I put it back in. I tried to "clean" the cartridge, and blow on both the cart and 3DS, but that didn't work (the cart was brand new; only 2-3 weeks ago, and I keep it usually inside the 3DS). Eventually, I gave up and called Nintendo to send it in for repair. I don't understand how a perfectly fine cartridge could just wipe out, and seeing how apparently no one else on the web has run into this problem as a result of Powersaves, I'm doubting its mainly Powersaves fault, and probably a cartridge issue. Any information, tips or assistance would be very appreciated. I'd like to not run into this problem again with future carts, or possibly even fix this mess myself.
