Its low price and simple design make it suitable for DS homebrew. It supports playing music and movies NES and Game Boy games (under 200kb) and Game Boy Advance games (under 256kb) from the CF card, and reading text files. The GBA Movie Player (GBAMP) is a CompactFlash adapter for the Game Boy Advance. However, this is not an easily portable method because the DS needs to be within range of a suitable Wi-Fi card. Strictly speaking, a storage device is not necessary for DS with FlashMe installed because homebrew can be sent to the DS using Wireless Multiboot or WMB.

Storage-device brands differ in their support for homebrew DS, 3DS and Game Boy Advance ROMs special features (such as ability to play media files) physical size and cost.

Although flash-memory capacity is usually measured in megabits (Mb), memory-card capacity is usually measured in megabytes (MB) (where 8 Mb is 1 MB). Storage devices with a memory-card slot usually have more storage capacity than flash-memory devices. The storage device either contains flash memory or a slot for a memory card to store homebrew.

There are also flash cartridges made exclusively for the Nintendo 3DS, such as the Gateway 3DS and Sk圓DS, which allow 3DS ROM backups to run in these systems. 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. Second-generation devices include R4 Revolution, CycloDS, G6 Real and DS-X. Second-generation devices (those which only use Slot-1) do not work with GBA homebrew, but as of 2007 became less expensive and easier to use, rivaling many Slot-2 devices in price.įirst-generation devices include GBA flash cartridges, GBAMP CF, SuperCard, and M3. Slot-2 (or first-generation) devices have been historically cheaper due to economies of scale (inherited from their use with Game Boy Advance), 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 which 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 also known as 'flashcarts' or 'flashcards'. Licensed developers, however, can use a blue Intelligent Systems Nitro Emulator box to flash cards. 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 (since the Nintendo DS is not sold with a rewritable storage medium).
