THE PATCH #1
doubble click and it will start working but wont open anything .. wait a while it will create a backup file.. dont waste your time on it.. get the same rom you wanted to patch and copy to you micro sd
I'm having a similar problem, where the game suddenly freezes during duels (opponent sets a card, FREEZE, I draw for my turn, FREEZE, etc.). This has only happened when I'm playing over wi-fi, but then again that's pretty much all I do. In fact, it did the same thing with WC 2009 last year, but at the time I hadn't bothered trying to find a fix.
I have an M3DS Real, using the latest Sakura 1.46 blah blah blah. Everywhere I look it seems like this version should've fixed everything, but I'm still freezing up at random.
I tried what riku88 suggested, but it happened again just now. Guy was playing Lightsworn, it crashed before I even had the chance to draw and now I look like a huge dick for disconnecting. Anyone has an idea? Like I said, it did the same thing with 2009, so someone must have figured what was the problem in that version, at least?
Edit: I've been thinking, is it at all possible that the problem lies in my MicroSD card or something? Clearly there's something wrong with my setup, because I see no one else with the exact same problem.
