Super Smart Boy
From PHWiki
Super Smart Boy was a Gameboy Backup Cartridge made by CCL as an add-on for their "ProFighter" series of SNES Backup Units. It attached to a Gameboy port on the right side of the ProFighter X Turbo, there also was also an add-on cartridge to use it with earlier ProFighter modells.
It has a built in BIOS, ROM-space is divided into four 1 MBit banks, each could hold one single GB ROM, bigger games used two to four banks.
To write GB games to it with a ProFighter a GB ROM has to have a proper Super Smart Card header, which can be applied with the swiss army knife of copier tools, Ucon64[1].
