German indexOn May 31, 1988, Gun.Smoke was put on the infamous German index by the BPjS. For more information about what this means and to see a list of games sharing the same fate, take a look here: BPjS/BPjM indexed games.
Since August 31, 2005, the game is no longer on the index.
Spanish versionDesperado started out as an unauthorised Gun.Smoke clone in Spain, but upon its release in the UK, publisher U.S. Gold, who didn't want to spoil its good relations with Capcom, obtained a proper licence, hence licencing the game retroactively.
TitleThe dot in the middle of Gun.Smoke was inserted by Capcom in order to avoid certain legal issues; namely, there was a popular American TV series that went by the same name, albeit without the dot. With the dot being rendered as a sheriff's star, most people hardly notice this difference.
