Quoted from slochar:My machine has system 7 firepower software in it custom written using information from this site:
http://gamearchive.askey.org/Pinball/Manufacturers/Williams/PinBuilder/text/williams_lvl7_programming.html#compatibility
Requires a system 7 board, obviously. All of the original ruleset was implemented from scratch and the following was added: (I'm probably forgetting some of the features....)
2x/3x scoring during multiball (depends on balls in play)
Spinner when lit counts value on another player display so you can see how much you're collecting
You can requalify locks during multiball by completing the standups
You can set the kickback to be lit at the beginning of the ball
A couple other people have this software as well and I know it made it to the TPF either last year or the year before.
Hi @slochar, these rules sound awesome! Are you willing to share these ROM files? I own a firepower with a system7 boardset and 7 digit displays.
