Gun Fight was released in 1975 on arcade cabinets everywhere within the US. Prior to that, however, Gun Fight had an interesting history. It was originally entitled Western Gun in Japan and was designed and programmed by Tomohiro Nishikado, of Space Invaders fame. It was published by Taito and released in Japan and Europe. The decision was made to then adapt it for Western audiences. This would be the first time a Japanese game was licensed for release to America. The title was changed to Gun Fight because it was thought that American players may find the current title odd or confusing. Dave Nutting and Tom McHugh of Dave Nutting Associates adapted the game for its new audience, making a few changes along the way.
Tom McHugh programmed Gun Fight a little differently than Nishikado—his programming and architecture called for the game to use an Intel 8080 computer microprocessor. It was the first arcade game ever to use a microprocessor, and the smooth frame rate and crisp graphics caused others, including Nishikado, to use microprocessors to their advantage in the future. Visually, Gun Fight was nice to look at—it ran at 60 frames per second at a resolution of 265 x 224 pixels. It made use of a black and white raster monitor with a yellow screen overlay, allowing the characters to look a bit more colorful than their counterparts in competing cabinets.
