I read somewhere that AR products before version 1.60 and up or something like that could not upgrade to the 1.70 which was used for Pokemon Black/White, but 1.55 was a way to use Pokemon Black codes for my AR, so I used that one. I've tried looking for firmware updates, but I can only find the most recent, which won't work for my AR because it's old.

I also tried restoring to "factory settings" by just resetting it, but even after readding the codes, it still has the same problems.

Well, at least I got a lot out of my game and AR before it became buggy.
