I got my supercard to work for about a week on my 3ds before I put some new games on it. once I plugged it in to my 3ds again it went through its initial setup/update...well it froze on this screen, so I shut it down. now it tells me "error has occurred" when I try to play on 3ds. it works fine on ds lite, I have tried several solutions none of which get the supercard to work on the 3ds. is there a firmware "reboot" or something?
