"Super Pro Fighter Q is a backup unit or copybox for the SNES, produced by the company China Coach Ltd, and released in 1993. The unit was to be inserted into the cartridge-slot of the SNES. It consists of a 3.5" disk drive, in which diskettes containing SNES ROM files was to be inserted, and it had a cartridge-slot of its own. Cartridges could be inserted in the Pro Fighter cartridge-slot and the ROM contents could then be saved to one or more disks, depending on the cartridge memory size. The process of loading the game from the diskettes into the unit's memory would last 60 to 120 seconds, depending on the size of the game.
The unit was able to backup games up to 16 megabit big. The Super Pro Fighter Q Pro, an improved version, was able to backup games of 24 megabit. The device cannot backup games with an additional chip, such as the game Star Fox. Additional functions include real time save functions and Gold Finger cheats codes."
