Mega Memory Card

The Mega Memory Card is a third-party Game Boy accessory which allows you to back up the SRAM save data from a game cartridge into the Mega Memory's internal flash memory. The cartridge has an upside-down cartridge slot to connect the cartridge you want to back up memory from, similar to GameShark and other Game Boy cheat devices. The device has a switch which allows you to bypass the Mega Memory software and run the game on the cartridge in the second slot.
