I am not able to repeat this issue either. It's fine my end with the latest release. |

Somehow, when I deleted the bosco.cfg file it fixed it. Don't know what that had to do with the sound? Edit: When I change the bonus fighter dip to 30K, 120K and every 120K it breaks the sound. |

I tried changing DIPs including the bonus fighter DIP and I couldn't get it to break the sound. If you could delete the bosco.cfg file again and record the steps to reproduce the issue, that might help. Thanks |

Change lives from 3 to 5 and change the bonus fighter to 30K, 120K and every 120K and see if it breaks. |

that's a very strange and specific condition for breaking it.. I wonder if this one is just a flaw in the game |

also only seems to happen on the Namco sets, not the Midway sets... I'd be really interested in knowing if this happens on hardware |

This never happened in previous versions of MAME either. Doing this on MAME 0.225 doesn't break it, also I don't think it regressed in the current version MAME. I'll have to mess with it more... |

I was unable to replicate this on real hardware with romset "bosco"; the explosion sound works just fine with those DIP switch settings. It only seems to happen sometimes on MAME 0.244, if you reset the CPU, it sometimes works fine, but other times the other explosion sound is also cut off. |

Getting some interesting results in MAME 0.243, the shot sound and the space mine explosion is broken after changing the DIP switches. The sound was completely normal in MAME 0.239. There was a regression in MAME 0.240 with the shot sound and the space mine explosion and a different regression for the current version with the enemy bases. |

Tested in 0.243 Linux SDLMAME. That issue only had happened when disabling cheats and plugin highscore and selecting "5 lives" and "15K and 70K only" doing an soft reset. Doing an hardware reset with same settings not happen that issue. |

Does MAME switch the sample on and off again, while the original analogue explosion sound circuit can only trigger it (switch "on") while "off" takes no effect? Many analogue drum machines behave this way (and often need a short pause to recharge a capacitor before they can be retriggered). If yes, it should be handled as an "edge triggered" event. I also found situations in "Pole Position" where in MAME the explosion sample gets randomly truncated. |

Tracing this using the example posted for the 5 lives and certain dip bonus levels - playing from start and letting Demonstration show the base explosion - it started happening when z80 timing changes focused on spectrum computers was committed April 25, 2022 https://github.com/mamedev/mame/pull/9449 https://github.com/mamedev/mame/commit/44dae68dbb5cd5d9fbb56e919e7bb59644830d2c |

That explosion sound bug also happen with sxevious. Try reach the boss and hit few enemies and not move the solvalou. Randomly not will play the explosion. |

This bug was fixed in MAME 0.250 with the new bosco ROM set. https://github.com/mamedev/mame/commit/cf29455ae1d84d73cb8fea22a1297d234abf28f8 |

I don't think you can call it fixed. It's clearly some weird race condition / sync condition with the emulation, the fact that it only triggers with specific dipswitches that must alter the timing of the game by some miniscule amount tells you that. The way it apparently randomly affects other games (Super Xevious) also suggests it's a deeper problem. There's probably some weirdly specific way to get the other set to drop sounds too. |

Sorry for the confusion, I had the chance to test this again with the new bosco set and specific DIP switch combinations leaves the sounds normal while other combinations do indeed break sounds(shot sound, space mine explosion, base explosion). I’m sure the other sets behave like this too, including the midway sets. |

I can't repro this on 6dc6efdbb58dad8f79d053f70b84550d6f99e53c, but it might be fixed with https://github.com/mamedev/mame/pull/11069. Can you post the most current repro steps, and/or test that PR? |

It seems that a bug with Arabian is related to the initial batch of changes to the MCU type for the Namco customs https://mametesters.org/view.php?id=3916 |
