Devices that only use SLOT-1, or 2nd generation, do not work with GBA homebrew, but as of 2007, they are becoming easier to use and less expensive, rivaling many SLOT-2 devices in price which may have been cheaper.įirst generation devices include GBA flash cartridges, GBAMP CF, SuperCard, and M3. SLOT-2, or 1st generation, devices have historically been cheaper due to economies of scale inherited from their use with Game Boy Advance homebrew but require a booting tool in SLOT-1 in order to use the touch screen and other DS features. There are two main classes of flashcarts: older devices that fit in SLOT-2 (the Game Boy Advance Game Pak slot) and newer devices that fit in SLOT-1 (the DS Game Card slot). These devices are commonly known as "flashcarts" or "flashcards". (Licensed developers can use the blue Intelligent Systems Nitro Emulator box to flash cards).


Nintendo DS storage devices are some of the devices used to store a licensed developer's work-in-progress images, homebrew video games, or downloaded commercial games, since the Nintendo DS is not sold with a rewritable storage medium.
