Bombjack Twin (set 1)
Bomb Jack Twin is a direct sequel to the 1984 original, and retains the same platform-based collect-the-bombs gameplay of its predecessor.
Changes over the original include a slightly faster playing tempo, and the option for simultaneous two-player gameplay. As with the original game, extra points and bonuses can be earned by collecting bonus coins and bombs with their fuses still lit.
Bomb Jack Twin also retains the 'Powerball' feature of its predecessor which, when collected, freezes the level's enemies for several seconds, allowing them to be destroyed.

Bombjack Twin (set 1) and M.A.M.E.
0.36b2 [Mirko Buffoni]
TEST MODE:
- Press Player 2 buttons 1+2 during reset. "Ready?" will appear and then press Player 1 buttons in this sequence: 2-2-2, 1-1-1, 2-2-2 and 1-1-1. The release date of this program will appear.
WIP:
- 0.141u1: ranger_lennier, Smitdogg and The Dumping Union added clone 'Bombjack Twin (prototype? with adult pictures)'.
- 8th January 2011: Smitdogg - We dumped the Bombjack Twin prototype (has girls after the bonus screens).
- 25th December 2010: Smitdogg - We got a crazy rare Bombjack Twin prototype board, the only one of its kind I've ever seen. It might be a one of a kind.
- 0.133u1: Brian Troha added DIP locations to Bombjack Twin.
- 0.124u1: Added clone Bombjack Twin (set 2). Changed parent description to 'Bombjack Twin (set 1)'.
- 0.57: Fixed cpu1 roms length to 128kb and added 2x proms (unknown).
- 0.37b8: Changed 68000 CPU1 clock speed to 10MHz, the 2x OKI6295 to 24242 Hz. Fixed sound1/2 rom loading.
- 22nd August 2000: Nicola Salmoria fixed a 68k bug affecting Bombjack Twin.
- 0.36b11: Changed clock speed of the 2x OKI6295 to 22050 Hz.
- 0.36b9: Changed clock speed of the 2x OKI6295 to 24000 Hz.
- 0.36b2: Mirko Buffoni added Bombjack Twin (NMK 1993). Some code has to be patched out for this to work (see below). The program remaps button 2 and 3 to button 1, so you can't enter the above sequence. I haven't yet figured out why music stops so soon, but it's surely due to interrupt timing (the hardware is so simple!).
- 1st August 1999: Mirko Buffoni added test mode code to Bombjack Twin.
- 28th July 1999: Mirko Buffoni fixed the sound and dipswitches in Bombjack Twin.
- 27th July 1999: Mirko Buffoni sent in a driver for Bombjack Twin.
- 31st January 1999: Dumped Bombjack Twin (set 1).
