Bonus Life Dip Switch
SW1, 2, and 3 of Dip Switch 2 are normally unused, and the service manual says as much. However, they were originally used for a Bonus Life setting. A routine starting at 5A07 handles the bonus life system, but the first opcode of that routine was changed from a "push af" to a "ret", effectively negating the process.
To re-enable this feature, change the value at 5A07 from C9 to E5, or put the following cheat in MAME's bombjack.xml cheat file:
<cheat desc="Fix Extra Lives Dipswitch"> <script state="run"> <action>maincpu.mw@5A06=E5C9</action> </script> </cheat>
|This is a preliminary level tileset. Most of the tiles are just hexadecimal numbers.|
|The sphere enemy was supposed to have a transformation animation. This is that.|

The extra credit message was corrected in the next board revision.
Get recordings of the Arcade Archives tracks.
As was quite common for arcade games of the time, Bomb Jack used a few tracks cribbed from outside sources as background music. The first level theme is an arrangement of "Kittens of the Apple Forest", the ED theme for the 1983 Anime "Mrs. Pepper Pot", the second level theme is an arrangement of the 1968 Beatles song "Lady Madonna", and the third level theme is completely original. (Notably, these appear to be officially licensed, as the Japanese flyer is labeled with the logo for the Japanese Society for Rights of Authors, Composers and Publishers.)
|Original||Tecmo Classic Arcade||Arcade Archives|
Unsurprisingly, later emulated versions of the Arcade game would attempt to replace these songs in various ways. The PS2 "Tecmo Hit Parade" collection erases the songs entirely, the Xbox "Tecmo Classic Arcade" collection overlays .wav recordings of music from its NES sequel Mighty Bomb Jack on top of the game (even replacing the third level theme, despite Tecmo having full ownership of that song), and the PS4/Switch Arcade Archives release edits the offending music data directly, creating new arrangements of the Mighty Bomb Jack tracks.
