This device is designed to sit on top of the Super Famicom, and features two cartridge slots.
The premise is that games could be produced at a much lower cost and development time, not having to rely on Nintendo for cartridge production.
This device was officially approved by Nintendo under the provision that Bandai handle all the hardware manufacturing itself.
Each of the 13 released games' boxes has a little picture in the lower left corner indicating whether linking is possible.
The included pamphlet features Tetris 2 + Bombliss which was never released for the system, but as a standalone Super Famicom game.
