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. The capacity of the cartridges can range from 64 Mbit up to 8 Gbit (Commercial carts range from 32 Mbit to 256 Mbit). More recent cartridges use external memory cards as memory, in place of onboard memory, such as Compact Flash, Secure Digital, etc. memory cards.
