Please provide an original PCB recording or video showing such to act as a reference as to how it SHOULD sound. If you don't have original references, we can't consider it "Verified with Original". Are you sure this is not a regression? Has it always been this way in your testing? |

Don't have it first hand however, but I did find a video on the original board (dating back to 2007, second video on the channel featuring this game shows the hardware running it as well). The warning music as you get closer to a game over is a continuous loop of a sample rather than one that has (about half a second) pauses every 2-3 seconds as the sample playback restarts like it does in MAME. Tested the same game in FBN for what it's worth, has the music samples playing back without pauses. I should try it in some older MAME versions first, I only recently got into games with spinner support. |

Gave MAME 0.157 a go https://github.com/mamedev/mame/releases/tag/mame0157 (now also 209, yes with matching romsets) Same results, both the mode select and warning menu has half a second pauses every 3-5 seconds instead of continous playback like in the above video. In-game music also has these pauses, but every 30 seconds or more as the songs are longer. |

Wanted to add that Guts'n also suffers from this issue with incorrect looping points, the music has pauses between each repeated loop. This can easily be heard in the short looping track that plays during the gameplay demonstration. |

At least, on my side - setting irq 11's timer from 8msec to 8.13msec (8130000nsec) fixes the music loop-points in sengeki striker, puzzloop & guts'n. |

I tried to force 8.13ms, and it improves the music looping in sengekis, but not in puzzloop or gutsn. The weird main xtal/1824 timer is probably not accurate either? It seems very close to hsync timing. And the 8ms one might be hsync*128. (note that doing it that way based on scanlines, doesn't solve this bug either) |

not sure why puzzloop/gutsn are working fine on my side, sorry! I also wondered about the 1824 timer, hrmf... |

are the idle skip speedups throwing it off somehow? |

Haze, I tried w/o idle speedhacks, no improvement. tried -nodrc, just for fun, and the music in gutsn and puzzloop loops fine. I can only guess there is some sort of cycle discrepancy in drc best regards, - dink |
