I didn't know where else to put it so I'm putting it here. With the new action replay DSi we can copy game saves to a micro SD card. I've done that just fine with Golden Sun Dark Dawn but when I try to do it with Pokemon Black it keeps trying to tell me my game card doesn't exist. Could somebody please tell me why?
Either you didn't put the game card properly in, the Flashcard isn't updated to the latest update, or the game file itself is broken. Put the game card in properly, and if it doesn't work, then update to your latest one. If you already have or have done the update but it isn't working, then get a new pokemon black rom.
I'm not using one of those fakey things. This is my for real game card with my for real DSi and my for real action replay DSi.
