Game Doctor/Professor SF

Known in Hong Kong as "超任博士" (literally means Super Nintendo Doctor), this unit was designed for the backing up of Super Famicom/Super NES games.

GB Xchanger

This unit was designed for the backing up of Game Boy and Game Boy Color games. It was also used to write said backups onto a flash cartridge for use on the consoles in question. The unit was designed with a Game Boy-specific slot on the top of the unit and took 6 AAA batteries or a 9 V adapter for power, and it connected to a PC via a parallel port.

Neo Flash Linker

This unit was designed for the backing up of Neo-Geo Pocket and Neo-Geo Pocket Color games. The physical construction was identical to that of the GB Xchanger unit, save for the Neo-Geo Pocket slot on top, as opposed to the Game Boy slot. NGP flash carts were also available.
