hi i have a itouch ds and i am having trouble getting it to work i downloaded the software version 3.8f. when i try using it the main screen comes up and i click on a game and it says saving file and then goes to the game and then the screen turns black it is driving me nuts. the only think that may be the problem is i am using a 2gb micro sd card ? does the itouch support 2gb sd cards or does it have ti be a least 4 gb card as the package of the itouch package states supports both the micro sdhc and micro sd 9capacity over 4gb) anbody have any ideas on what the issue can be please help thanks
