So is there any reason to play any model of Game Boy released prior to the AGS-101 besides nostalgia? The link cable works with the SP models from what I remember. The only thing I don't think works with the SP is the little infrared link thing on the GBC but I thought that was just used on lieu of the physical cable. Doesn't every GB/GBC/GBA game from every region work on the AGS-101? The only advantage I see with the older systems is that the cartridges don't protude out like they do on the SP
