OK, I confirmed the slow down occurs there, just only in the s1945jn sets. Other protected and bootleg sets are not affected. It is not MAME's but in-game slowdown like many cave games. As you mentioned in your report, since you confirmed it against the arcade version, could we have something to prove that it is same as the s1945jn set? Thanks. |

Oh,yes, just only in the s1945jn sets.. The arcade version that I played is "s1945j". Sorry for my mistake. |

I found that with the bootleg, which is based off this set, I had to invert the vblank flag compared to the main sets. On the bootleg the problem was more severe, all the sprites would go invisible when it slowed down. I'm not really sure what to make of it tho, the vblank is clearly right for other games, but this set is on different hardware, but I didn't want to make changes outside the scope of the bootleg I was emulating. |

It seems this game changes levels order. |
