SuperCard Lite
From Dev-Scene
The SuperCard Lite is an NDS cartridge that accepts a micro SD card, unlike its older brother, the SuperCard MiniSD. It allows the user to load NDS and GBA games from the micro SD card and run them, and also allows the user to switch between programs by pressing L+R+B+START. Pressing L+R+B+SELECT causes the NDS to display a menu that allows the user to save the game state in a *.sav file or load such a game and resume play.
The SuperCard Lite is capable of displaying e-books and playing music and video. It uses the FAT filesystem format. Like the SuperCard MiniSD, games must be processed on a full computer or laptop to circumvent certain security keying mechanisms in order to allow them to be played from the micro SD card.
It was the first such cartridge that fit flush with the NDS enclosure.
