Bonanza Bros (Japan, Floppy DS3-5000-07b Based)
One or two players take on the roles of Robo and Mobo, two cat-burgling brothers who must carefully make their way through a variety of scrolling platform-based levels, stealing a number of valuable items (as highlighted on a cut-away map displayed in the middle of the screen). Once all of the treasure items have been acquired, the brothers must quickly make their way to the roof to escape in a waiting airship. Each stage must be completed within a set time limit.
Bonanza Bros. introduced a 3-D element to the traditional 2D platform gameplay. Both players and enemies can move between the front and back of the platforms, with the enemy guards having a 'field-of-vision'. This made it possible for players to hide from the guards by ducking behind furniture, as well as into alcoves and stairwells.
If players get shot by the guards too many times, or if all of the treasure is not recovered and the escape point reached before the time limit expires, the brothers end up in jail and it's game over.
Each of the game's ten stages is set in a different building the brothers have to burgle. These include a bank, a millionaire's mansion, a casino, a mint, an art gallery and a treasury.

WIP:
- 0.144: Implemented FRC hook-up to Sega System 24 HW, fixes missing SFXs to Bonanza Bros [Angelo Salese, Phil Bennett, Charles MacDonald].
- 10th November 2011: Angelo Salese - Investigated with Phil Bennett and Charles MacDonald about why Bonanza Bros never ever played samples from when it was marked as working. It turned out that Sega System 24 HW uses a FRC that also does a previously unemulated IRQ service.
- 0.133u1: Renamed (bnzabrsj) to (bnzabrosj).
- 0.121u2: Added coin slots 3 and 4. Changed description to 'Bonanza Bros (US, Floppy DS3-5000-07d? Based)' and clone '(Japan, Floppy DS3-5000-07b)' to '(Japan, Floppy DS3-5000-07b Based)'.
- 0.101: Added new disk image ds3-5000-07b.img to clone (Japan, Floppy DS3-5000-07b).

- 0.79: Added 3rd button.
- 0.78: Fixed user1 roms addresses ($100000/1).
- 14th December 2003: David Haywood fixed the ROM loading in Quiz Rouka Ni Tattenasai and Bonanza Bros, so that they both work more or less perfectly now.
- 0.77u3: Olivier Galibert fixed Bonanza Bros - Game now playable. Removed button 3/4 and 3rd coin slot. Added dipswitches 'Coin A/B', 'Demo Sounds', 'Start Credit', 'Coin Chute', 'Monitor flip', 'Difficulty' and 'Initial lives'.
- 3rd December 2003: Olivier Galibert fixed the controls in HotRod and Bonanza Bros, and HotRod was made playable by the addition of a ROM mirror thanks to GreyRogue's findings.
