context_page_description: Nintendo DS and 3DS storage devices are used to store a licensed developer's work-in-progress images, homebrew video games, and downloaded commercial games. Licensed developers, however, can use a blue Intelligent Systems Nitro Emulator box to flash cards. These devices are also known as "flashcarts" or "flashcards". There are two main classes of flashcarts: older devices which fit in Slot-2 and newer devices that fit in Slot-1. Slot-2 devices have been historically cheaper due to economies of scale, but require a booting tool in Slot-1 in order to use the touch screen and other DS features. Second-generation devices do not work with GBA homebrew, but as of 2007 became less expensive and easier to use, rivaling many Slot-2 devices in price.
  First-generation devices include GBA flash cartridges, GBAMP CF, SuperCard, and M3. Second-generation devices include R4 Revolution, CycloDS, G6 Real and DS-X. Many of these devices also work with the Nintendo 3DS as DS flash cartridges, allowing DS ROM backups to run in game consoles of the Nintendo 3DS line.
