DSTT and DSTTi For Nintendo DS, DS Lite, DSi

The DSTT, DSTTi card is the same size as an original card, which is extremely easy to use. All you need is a MicroSD card. Since the DSTT, DSTTi is SDHC compatible, you can use any of the high capacity cards (4GB, 8GB etc). If they strike your fancy, normal MicroSD works perfectly fine as well.
