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 E5 to C9, 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.
