The game program has a process to detect the third button, and you need to press the third button when moving while hanging, but this is not necessary in the actual game. I suspect this is because the specifications were changed from 3 buttons to 2 buttons before release, and the wires were directly connected without using buttons. |

Ah I see, I'll re-add the button then for this game. Opinions are divided: IMO MAME should only emulate buttons that are on the control panel, rare exceptions aside. Others will say that if the game has any way to detect it, like here in Galivan, or the 3rd button in testmode in Ninja Emaki, MAME should emulate it. Or in extreme case, some will say MAME should have inputs on all ports that the hardware can access in theory (which would be a lot). |

This is just my personal impression, but if you're going to reproduce not only the operation of the circuit board but also the wiring of the levers and buttons, I think it would be more consistent to make those wiring the same as the original. That said, I naturally respect the MAME development team's decision. |
