I've had my CycloDS Evolution (firmware 1.41) for a few weeks now, and other than one little problem, it's a great little device. When I sometimes access the in-game menu with A+B+X+Y+L+R, the top screen will go white - and completely lock up. If I kill the power and start the DS Lite back up, everything is back to normal. I've tried formatting my microSD and microSDHC cards - no effect. This happens occasionally - maybe 1 out of 20 times I try to access the menu, and it really bugs me. Is this normal behavior, or is it possible that I have a defective unit?
