Bonanza Bros (US, Floppy DS3-5000-07d?) - MAME - Arcade Action

Bonanza Bros. is a strategic platform shoot-em-up with one or two players taking on the roles of Robo and Mobo, two cat-burgling brothers who must negotiate scrolling platform-based levels and steal a set number of valuable items, before making their way to the roof to escape in a waiting airship. The location of the items is highlighted on a cut-away map displayed in the middle of the screen and each stage must be completed within a set time limit.
