Ok, I'm working on getting the supplies together for another run of 10 cables. Please send me a PM if you are interested in a cable. Cost will probably be $25 shipped in the US, and a little more for international shipments.
Theoretically you should be able to use any GBA->GC cable for this. Just use the wiring scheme shown in the photos on the first page. I've run into a few that don't work, but they were super cheap-o Chinese knockoffs. Remember that you MUST use the official Nintendo Gameboy Micro link cable.
