Superkey
The newest product in the Supercard line up is the Supercard DS One. The SC DS is a Slot 1 solution, meaning instead of using the GBA slot it uses the DS slot and is the same size as a standard DS game. This means you will no longer need a Superkey in order to play in Nintendo DS mode! It is an all-in-one solution, just add a microSD memory card and you are ready to go!
Feature list:
- Uses a standard MicroSD/Transflash memory card.
- Plug and Play (no need for an additional GBA cart or any type of Flashme/Passme device)
- 100% support for clean ROMs - no need to patch anymore
- no PC software required, just drag and drop the file from your PC to the micro SD memory card
- Hardware save support, Unlimited storage, supports FAT, FAT32
