We've posted before about Japan-only Capcom key chains, but these are kind of special. As you can see from the video above, you can perform moves of three Street Fighter characters per keychain on an NES-looking controller scheme. That's not the best part, though. Keep watching the video and you'll see that you can "duel" another player with a 2nd keychain. That's...frickin....awesome! More details in a language I cannot read here.
