Marcan from Team Twiizers has uploaded a video showing off his custom made GameCube to Nintendo Wii controller adapter. This adapter allows you to use the old controller on your Nintendo Wii with only some limitations. Quote: Here's a video of a little gamecube pad to Wii Remote adapter that I rigged up. The console sees the adapter as a Classic Controller. It's missing some buttons (-, home, ZL), but those are rarely used (Start maps to +). This lets me play SSBB, Mario Kart, and VC games using a plain GameCube pad without having to use the questionable Classic Controller, and without a WaveBird. It also works with the System Menu, as you can see in the beginning of the video. Since WaveBirds are out of production, this is probably the only way of using an official Nintendo GameCube pad with the Wii, wirelessly. The guts: a PIC18F4520 microcontroller, and that's pretty much it. A couple resistors and capacitors, and the quartz crystal are all that there is to the hardware part. I cut up a Nunchuk extension cord for the Wiimote plug, and made a crappy GC connector out of a piece of circuit board. This uses the Wii Remote's power supply. The big flashing board that you can see to the left is an FPGA used as a logic analyzer for debugging, but it has nothing to do with the actual adapter (I unplug it halfway through the video).
