O. The game likes Hook (4-player setup). That makes sense. It needs 2 cabs for 4 players and extra 2 speakers.
Wish it can be made the stereo output for M92 games. If it can, it's the good news for the M92 multi!!!!
My opinion is that you can still keep your original baseball batman. And you should buy a donor board for the M92 multi.
My case is i also bought the original Dragon Spirit board and i bought the tank force as the Darksoft Namco System 1 multi.
