A flash cartridge is one of several cartridges containing flash memory that have been developed for use in video game consoles. These cartridges enable homebrew applications and games to be used. Flash cartridges offer a means of storage for keeping the games until a user decides to run a game, which then it is copied to the cartridge's game ROM for the console to run the game as if it were a normal ROM cartridge. The game storage can be in the form of onboard flash memory on the cartridge, although more recent cartridges use external memory cards as storage in place of onboard memory, such as

memory cards. Recent flash cartridges may also use RAM instead of ROM for flashing games to run on the console as a way to offer faster loading times than what is possible on reprogrammable ROM. These cartridges remain the best-known way to create and distribute homebrew games for many consoles, such as the

. (another option in this case being the GBA Movie Player, which can run specially designed homebrew programs but cannot run illicit copies of commercial GBA Game cartridges due to the lack of onboard RAM for fast data access).

Linkers

Games are written to the cartridge with a device called "linker". Depending on the brand of flash cartridge, the linker either connects to a link port on the console and writes to the cartridge through the console, or connects to a mini-

Flash card adapters

A number of devices have been released which use popular flash memory cards such as SD and CF for storage. These have proven popular since the development of techniques to run Nintendo DS software from a GBA cartridge, due to the smaller size of DS games and the low price of these cards compared to conventional GBA flash cartridges. Examples of such devices include the M3, R4 and Supercard.

Software

There are those that use a program calle

Some flash cartridges use specialized software designed for the specific cartridge, such as Power Writer and USB Writer software for the Flash2Advance Ultra cartridges. This presents several conflicts in regard to homebrew, as Power Writer uses a large database for proper naming and saving of games. ROMs that are not in the database (such as emulators or any other GBA homebrew) are prone to saving issues, and editing the database manually is difficult and involves the use of a

Other Nintendo flash cartridges

Flash cartridges are also available for other Nintendo consoles, such as the DS, DSi, and the 3DS. The DSi and the 3DS have the ability to update their system firmware via the

Official flash cartridges

Some game consoles have official flash cartridges (and official emulators) used by developers to test prototypes of their games. These cartridges are usually part of the console's software development kit and are only available to licensed developers.
