Obviously it won’t be playable for some time but it would be part of the whole and providing assistance to those that need to diagnose their board. And it has graphics so it would be possible to see gameplay minus the trippy laserdisc images.
Sadly my driver writing skills are weak. Actually part of the problem is the existing rom dumps are not named properly so I need to study the schematics or find a decent picture of the board.
In the meantime I found some interesting history on the game.
