Back around the time the Gamecube and it’s hardware specifications were first being shown off at E3 2001 Nintendo stated that the Hi-Speed port was basically a port for any console add-ons or peripherals down the track and that for the time being they weren’t sure what any of these expansions may be. I can’t remember exactly but I believe that the default assumption was that it would be similar to the Nintendo 64’s Memory Expansion port which later housed the Expansion Pak. That is, some sort of additional processing power for the console.

Eventually a year and a half later Nintendo released the GameBoy Player which was the only such peripheral to ever take advantage of this port. Which kinda makes me a little suspect as to what Nintendo were originally planning to use the port for. So I’ve thrown together some ideas of my own which I think would have been realistic of Nintendo and the hardware, feasible as well as useful for the consumer.
