The driver should be more accurate now than before. I'd like proof that this doesn't happen on the real machine before start chasing this down. |

To be honest, I've seen a lot of one frame only bugs turn out to be original behavior in the end. It's good this is listed as possible, at least. |

I had a bootleg pcb for sometime and I am resonably sure this bug didn't happen on real hardware. Since I repaired a sprite problem on that bootleg, I payed a lot of attention to gfx, I don't remember that garbage. btw I agree we should have proof from real hardware |

when the sprites exit from the screen at the top of the screen they appear at the bottom; this it's not a bug in this video you can see this (33 seconds) in this video you can't see the graphic garbage when the planet disappear in mame you see the garbage in the same situation in this video the high scores table appear from the bottom in mame the high score table appears in only a frame another link; in this the high score table appears in only a frame but there isn't the graphic bug maybe the problem is related to these infos: 27 a701 Semaphore system: tells 6809 to draw queued sprites 28 a702 Semaphore system: tells 6809 to queue sprites |

ok the problem is the sync between cpu#1 and cpu#2 it's necessary to specify a interleave value: MDRV_INTERLEAVE(100) fix will be submitted |

What about the transparency of the text over the sprites? MAME currently checks a bit and if it is set, it draw the text opaque. But in that video (at 31 sec), it clearly looks like that the sprite is over the lives remaaining indicator. |
