No, but if you get funding, and pay me for my time, I’ll help you design and build it. However I’ll say up front that it’s a nearly-impossible request to make an actually accurate Wii simulation of boxing, as the controls are not accurate enough, and the interface would only let you make some sort of approximate simulation that would somehow correspond to what the player was doing by making a lot of generous interpretations. Most Wii games do this even with their arcade games – they just detect when the user made a swipe and then very generously interpret that as a canned attack by the player’s character in the game.
