Original Sega Shinobi System 16B circuit boardset that boots up and plays with some noticeable video issues. We did some basic troubleshooting and plugged an Altered Beast rom board into the main board and the video issues went away. So we do believe the issue is with the rom board, but we don't have the time to pursue it.
Both boards are very clean and in nice condition, the game does play with sound, but again has some video issues that we think have to do with the rom board.
See photos for more details. Boardset sold as-is, needing repair.
