Bomb Jack (set 1)

0.35b13 [Nicola Salmoria]

0.09 [Mirko Buffoni, Nicola Salmoria, Brad Thomas, Jakob Frendsen, Conny Melin]


- Press fire to skip the ROM/RAM test at the beginning.

- In the dip switch menu, DIFFICULTY 1 refers to the speed of the mechanical bird, while DIFFICULTY 2 to the number and speed of enemies. SPECIAL refers to how often the (E) and (S) coins appear.


- 0.104u3: Adam Bousley added save states support to the Bomb Jack driver.

- 25th February 2001: Olivier Galibert added save states support to Bomb Jack. However, the driver needs to be updated to include the save states.

- 0.35b13: Nicola Salmoria added Bomb Jack (set 1). Renamed (bombjack) to (bombjac2).

- 0.22: Nicola improved color palette emulation in Bombjack which has now perfect colors. Bomb Jack doesn't have a color PROM, it uses a RAM to generate colors and change them during the game.

- 0.18: Bomb Jack is much faster on a 486. Now runs very well with -frameskip 1 on my 486/100.

- 0.15: Jarek Burczynski submitted a sound driver for Bomb Jack. The game is now a bit slow on Nicola's 486/100, -frameskip 1 is almost good but not quite.

- 0.13: Fixed a couple of minor bugs in Bomb Jack background colors.

- 0.10: Fixed a small graphics glitch in the background of Bomb Jack's third level. Thanks to Philip Chapman for the report.

- 0.09: Mirko Buffoni added Bomb Jack (Tehkan 1984). Thanks to Brad Thomas, Jakob Frendsen and Conny Melin for the hardware info on Bomb Jack. Issues: Colors are accurate, but not entirely: the original machine uses 12 bits (4 bits per pen), while I currently use only 8 bits (3 bits for red and green, 2 bits for blue). Is the sprite priority correct? For example, during the demo, should GAME OVER be in front or behind other sprites? There is another bit in the sprite attributes which I don't know what means: It seems to be set only when the (B) materializes. For the DIFFICULTY 2 setting, EASY and MEDIUM might be swapped. Anyone can confirm? The INITIAL HIGH SCORE setting doesn't only set that, it does something else as well - but I don't know what.
