Burn new ROM. PM JROK.
https://forums.arcade-museum.com/showthread.php?p=3793535
Made some time to add updates to the board:
- Rapid fire option
- separate fast/slow high score tables
- "guest" high scores option ( both fast/slow ) so you have separate high table for when friends come over, overwrite all your scores and put a 10,000,000 "ASS" as the top

- each score table can be individually cleared
- For a 2 player game each player can select the firing speed. The high score at the top of the screen changes to fast or slow depending on what they picked.
- all options ( except for attract mode coin-up ) can be disabled
- These options are controlled in setup menu, not via dip-switches
It's backwards compatible with the older board hardware if anyone wants to burn their own ROMs ( any scores would be lost though ).
