A flash cartridge is a homebrew video game cartridge that uses flash memory for storage as well as running applications. These cartridges enable homebrew applications and games to be used and played when they are inserted into an otherwise officially licensed game console. The game storage can be in the form of onboard flash memory on the cartridge, although newer cartridges usually use external memory cards as storage in place of onboard memory, such as Compact Flash or Secure Digital. 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.
