Im on 1.55 and this has been happening for a while so i doubt that the new firmware would make any difference. I've been noticing lag in framrates in various games and its very bad in pokemon platinum and i notice framerate drops in gba games like final fantasy vi. This hasn't happened when i first got my cyclo this wasn't happening. Could something be wrong with my cyclo or could it be my (nearly full) 8gb sdhc class C2 card?
