Bombjack Twin (set 1)

0.36b2 [Mirko Buffoni]


- 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.


- 0.57: Fixed cpu1 roms length to 128kb and added 2x proms (function unknown).

- 0.37b8: Changed 68000 CPU1 clock speed to 10MHz, the 2x OKI6295 to 24242 Hz and the sound1/2 rom address to $40000.

- 22nd August 2000: Nicola Salmoria fixed a 68k bug affecting Bombjack Twin.

- 0.36b11: Changed the clock speed of the 2x OKI6295 to 22050 Hz.

- 0.36b9: Changed the 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.
