English releaseFinal Fight Guy did see an English-language release stateside as a Blockbuster exclusive rental game.
Version differencesFinal Fight Guy (1994) is almost exactly the same game as the original Final Fight (1991) for the SNES. The main difference: instead of Cody & Haggar you can now select Guy & Haggar. The intro has also been slightly changed; in the intro of Final Fight Guy, Guy says that Cody is still in Japan training his martial arts skills so it is up to him to save Jessica. That's all.
