It's a side effect of PORT_IMPULSE(x) (x = amount of frames input is active). This happens with every driver that uses this, not just Salamander. |

It no longer issue with gameplay, but I thought it might not perfect to use PORT_IMPULSE to fix this because it seems to be different from behavior of actual machine. PS: See also Tafroid's post at #08315. |

Even if you'd simulate the coin falling through the chute a more accurate way, like with an emu_timer, it would still be active very briefly in test mode. |

It not means about simulating physical behavior of coin. Sorry for lack of clarity. I think it is interrupt issue as this Tafroid's comment points to. May be current is degraded implementation, as it worked fine in previous MAME. https://mametesters.org/view.php?id=8315 Tafoid Wrote: > Seems to a casualty of raw screen parameter changes: > https://github.com/mamedev/mame/commit/e724f4d7e60c266138b1ab4ffd6cd2bb81858682 > > There was another commit after which fixed coins for another game in the driver, perhaps it may or may not have the answer: > https://github.com/mamedev/mame/commit/ad2e7a469463d02508c98a471332256e3e8621b2 |
