Ah, well, there goes that option then, haha^_^
I wonder what the cause of the corruption was, though. I also once had an corruption. My batteries died in the middle of a saving. Luckily I saved 4 times before on the same spot, so my game was able to go back to a previous save.
I kinda feel like a game should keep the previous two saves, so it has something to go back to.
I hope at the least they are able to tell you what caused it.
Huzzah! (I probably should fight alonside Maxie more. Lately I'm using Mega Sharpedo a lot, so a Mega Sharpedo and Mega Camerupt combo would be funny. And yes, Team Magma/Aqua really show us that they have turned good, instead of just disbanding and forever gone.)
Talking about the Battle Maison. I love it that you can get Wally's battle theme to play in the battle resort, I love that song so much.
