This is a long shot, but I'm assembling a Pioneer Balloon and wanted to see if anyone had a copy of the manual and/or schematics? Scan or physical or link are all welcome.

Trying to get some information about the power supply and the harness, specifically. I'm assuming both are very similar to the other SNK games (Nibbler/Fantasy) since they share a pinout, but not 100% certain

Thanks!
