Just what *is* the point of the posts you make here? MAMEdev is under no obligation to dedicate their free time to satisfy your personal desires. On the other hand, they would most certainly welcome any effort making this particular game playable in MAME, because they're usually too busy performing small (and sadly underappreciated) miracles all the time.
You have the PCB, so you're in a great position to contribute your experience with it to the project.
You can find MAME's git page here. We look forward to your pull request.
