A cartridge containing flash memory that enables unsigned code or ROMs to be run on a game console. Hard to find because the ESA thinks it encourages piracy.
When my GBA has a homebrew cartridge, it can play 90 minutes of stereo music per 32MB ROM, play 5 minutes of video in 16MB, and store 100 photos in 4MB, as well as play 8-bit NES games.
