Robocop uses YM2203, this driver has sound issues. |

Taking a closer look, this is similar to 6923, is hard to tell if the sound is playing or if the channel level is too low. |

Well I don't think is played too low, really is likely the sound is different or corrupted. I think the sound is the same I've reported in 06166, when batman hits with the attack button. |

I'm filling a report about the mame sound engine, maybe with that the developers could fix a issue that will benefit all this machines. |

Clearly related to 06740: Setting Overclock CPU: audio cpu to 150% solves the issue. |

Taking a look to report 01066, maybe this issue is related to it? |

Confirmed at my side. This was fixed between 230 and 231, when Aaron made a lot of changes to the ymfm core. But at 231 the bug is still present so maybe a later ymfm commit could cause it... |

Just like overclocking audiocpu 'fixes' it, underclocking maincpu also does. I see 68000 DTACK hooked up in the schematics, so I suspect it's that. |
