Looks like he just hacked the jamma ext harness that jammaboards.com sells. Wouldn't be too tough to make. Just remove the 28/56 jamma fingerboard and add 1 22/44 and 1 18/36. The pinouts are available for both jamma and Ninty vs. online. Instead of waiting for someone else to do it, just get to building.
I SO don't have the time to do that. Anyone want to cost it out and make a few? I'll buy one...
