SNES controller dock? That's exactly what we have here. The Dell Streak's ability to work with standard USB keyboards has enabled it to also work with a suitably modified SNES controller, having had a cablectomy and the addition of a PDMI connector on top. That, with the addition of a USB board, turns the controller into a keyboard and, hey presto, it's Super Mario World time. Modder 0TheRain0 did the handiwork here, which you can watch him demonstrate after the break.
