AKA: DS-X, DS Xtreme, DS-Xtreme, DS Extreme, DS-Extreme.
Manufactured by: DS-X
- The DS-Xtreme uses 512MB of internal NAND flash memory, and does not support memory cards. The DS-Xtreme has a mini-B USB port built onto it which doesn't stick out, and still allows the DS-Xtreme to sit flush your Nintendo DS. And there's no need for a PassCard as the DS-Xtreme already has PassMe functionality built in.
- One single unified device, no need for GBA Cart, external memory or passme/flashme
- Functions as a flash cart, compatible with homebrew, media and other image files
- Plug ‘n Play, no PC software required allowing for some seriously sweet Drag ‘n Drop file transfer
- Intuitively designed custom operating system which is fully upgradeable
- Included 4GBit (512Mbyte) onboard flash memory
- Hardware design compatible with all current and future DS consoles, same size as original DS cartridge – does NOT stick out!
- Custom engineered components such as a High-Speed USB 2.0 mini-B connector and full sized EEPROM.
- Excerpt: "So it the DS-Xtreme worth the cash? If you want a reliable, highly compatible slot 1 solution and are happy with 512MB of space, then the DS-Xtreme is definetely for you if you can fork out the somewhat hefty price tag. The DS-Xtreme has raised the bar for all flash kits to follow and it will be interesting to see if others can match the quality set by the guys at DS-X."
