Quoted from russdx:
Could this game be saved with new software? / lcd display? or is it the actual layout is severely flawed as well? Maybe some one can create a bolt on kit like a raspberry pi running the mission pinball framework with completely new rules / audio with a lcd screen you add on (like installing a colorDMD) and then you would create some sort of hardware bridge to drive the actual hardware via the current driver board. So basically the game does not boot using its own firmware but uses the new raspberry pi controller.
Can it be saved? Whats letting it down so bad?
AFAIK the controller board is a copy of Bens https://github.com/LonghornEngineer/Pinheck_Pinball_System which is used in AMH and therefore it should be possible to programm your own ruleset etc.
