AmigaUnlike the other versions, the Amiga version was not an official release by Beam Software & Melbourne House. It was instead made by the Polish company World Software, whose developers enjoyed Bad Street Brawler so much they decided to make their own version for the Amiga using, among others, sprites ripped from the ZX spectrum version.
NES versionIn the NES version, some enemy sprites are changed: the blind man was changed to a thug, grandma is now a small Italian, the basketball player is white and the skull on a bomb was removed.
Power GloveBad Street Brawler was along with Super Glove Ball the only games designed to showcase the Power Glove that were released. Two other additional titles were scrapped.
SpritesBad Street Brawler uses sprites that are doubled in height and width before being displayed. This results in big sprites, but they look blocky.
StagesAfter stage 10 Bad Street Brawler goes into infinite repeat mode; stage 11 is the same as stage 6. However even the stages 6 to 10 are nothing more but rehashes of the stages 1 to 5 with more & tougher enemies.
