If you into the Wii hacking scene, then you no doubt have heard of the D2Prog (a Wii modchip). Well a hacker known as Dream over at Xbox360hacker
has found a way to run PSGroove off a D2Prog, what he calls "D2Groove". You will need a PIC programmer to flash the PIC (you can buy
a JDM programmer for cheap).
The D2Prog are relatively cheap and are about $25, so grabem while they are hot.
Video of it in action here:
