Flash carts have been available for the Nintendo DS and Nintendo DSi for quite awhile. Brands like the R4 or AceKard 2i have really opened up the DS flash cart market to the masses and driven the technology. The developers of the Supercard DSTWO have been paying close attention to the trends. They have taken the best features users expect from a DS flash cart and added their own line of improvements and additions. It is no wonder the release of the Supercard DSTWO has been attracting so much attention.
