Cartridges referred to as Nintendo DS cards as also the later versions called Nintendo DSi cards were initially developed to give the users of handheld Nintendo consoles the ability to play games and movies and music as well. The latest versions of DS cards let one use a variety of homebrew software and also bring eBooks and PDFs to your monitor too.

The DSTT was one of the first ever cards ever to be manufactured to suit the Nintendo DS lite and the Nintendo DS and it owes its popularity to this. The card is the second card that made its way coming after the famous R4i card, also referred to as the R4-0815 or the R4v2.
