Nintendo's Punch-Out!! remake hit the Wii this week, and as you can tell from my review, I think it's pretty brilliant. One of my few critiques of the game was that the motion controls weren't as much fun to play with as the old-fashioned, digital controls. That opinion might've been a little different had Nintendo implemented something a little more like what DIYer Sam Seide has cooked up here.
Sam has posted full instructions on how you can fabricate this same setup for yourself on Instructables. If you're unfamiliar with SlamMan, here's Sugar Ray Leonard to fill you in, courtesy of the Canadian culture jammers at TV Carnage.
