On top of all this it also has the handy real time menu. The SuperCard DSTWO features a menu very similar to that of AKAIO, possessing the ability to do things like copy/cut/paste/delete. In short the DSTWO can do GBA emulation with only slot-1, video playback without conversion, better SNES emulation than other flashcarts, and whatever else the homebrew community makes for the DSTWO.
It takes the great support of the SuperCard team and puts it in a 2nd generation flashcart (which means it has an imbedded CPU) that can do things no 1st generation flashcart can do. The SuperCard DSTWO is one of the best flashcarts available for the DS to date.
