Teddy Boy Blues is an updated conversion of the 1985 Sega coin-op action platformer. While the basic premise is similar to the Master System version -- each stage contains a number of enemy generators, and enemies must be shot and collected before they take a portion of the time meter -- this version of the game has several differences. The graphics have been redrawn to take advantage of the more powerful hardware and the Yohko Ishino tie-in has been removed. There are also several new stages throughout the game, though many of the original game's stages are also present.
