I've read some older threads about the 2.1 freezing when attempting to save (the thread is located here: http://gbatemp.net/index.php?showtopic=201192 ). Was the cause of this freezing ever discovered (like the card being from a clone source)? Essentially I want to know if it is safe now to buy a 2.1 card for a DS lite without having to worry about defects. By the way I'm looking to buy from realhotstuff.com. Anyone here have good experiences with them in the past?
