back in the day it was planned to be ported to nes but it never got released,an older biuld of the game has been available on net for a while but a much newer biuld of the game has just been released.
The Way of the Exploding Fist was a Karate Champ-inspired fighting game released in Europe in 1985 for the Amstrad CPC, the Commodore 64, the ZX Spectrum, and the BBC Micro. The C64 port was the only version to arrive stateside. An NES release (simply titled Exploding Fist) was planned, but never released.
The NES version was to be published by Tradewest, apparently, with development handled by Beam Software, of The Three Stooges fame (and Bad Street Brawler infamy). The sprites are fairly large, and one of the modes allows two players to beat up on an AI-controlled third opponent, which is kind of neat.
Otherwise, the game suffers from a lack of content, and doesn't do much to expand on the concepts introduced in Karate Champ, which might explain why it was never released. It's worth noting that even the newer version may still be incomplete, though we currently have no way of verifying this.
Tip: If you want to win, just hold an upper diagonal on the d-pad until you kick the other guy in the face, and then keep doing that until the end of the match.
thanks go to everyone involved with this release.
