Bonanza Bros. is a game where two brothers rob a bunch of houses. It's actually very enjoyable.

The US/European version adds a "TM" to the end of "SEGA" in the title screen, which the World version does not have. After the title screen fades out, the World version shows a "Wanted Dead or Alive: Bonanza Bros." sign on a brick wall, with the Bros going left, passing by the sign. The US/European version skips straight to the scene for what the Bonanza Bros should do. When the US/European version is played on a Japanese Mega Drive, nothing is changed, besides having no "TM" in the Sega logo screen.

The storyline was also changed between versions. In the Japanese version of the game, the Brothers are thieves who are out to steal the treasures for their own gain. In the Western versions of the game, the two are testers for a security system and making your way through the levels is the method of testing this system (presumably made up of guards and dogs).
