That's def' a Sky Kid type daughter board and in the manual it talked about how you can run any second game off the board in a dual system. You can run any game on that board.
So, looks like someone removed the other game (sky kid, etc.) and it just has Hogan's Alley on it. But I don't see how Hogan's Alley is working with the single ROM that I can see installed?
