Bonanza Bros. (1991) is a shooter-platform game that was first released in the arcades and then ported to the Sega Genesis, and can be played in a cooperative 2 player mode.
The plot involves the Bonanza Brothers: Robo and Mobo, who resemble the Blues Brothers, but are thieves who steal many treasures from banks, mansions and casinos.
In this run, the author steals as many treasures as he can and avoids the police by controlling the 2 players... at the same time!
