Problem saving in Acekard2

Hi, I'm using an Acekard2 with the akaoi 1.5.1 firmware and Yugioh World Championship 2009 refuses to save.The problem is this save point is automatic(i.e. "Saving...don't turn off power"), the game just stalls.Is their a fix for this?I'm using a 1GB sandisk memory card that has already been formatted.

how long ago did you get your acekard, alot of people from the GBATemp forums have been having problems with defective AK2.1's that were bought recently.check this threadhttp://gbatemp.net/index.php?showtopic=201192
