| Description |
For some reason the computer is doing a lot of mistakes during attract mode and gameplay in comparison with MAME 0.196: - In the first minutes of attract mode, the car get out the racing track at the first corner (verified with original) - During attract mode, It has trouble to pass other cars (verified with original) - Traffic cars at the wrong position on the racing track (verified with original) - Near the end of the attract mode, the arcade show that the main racing car pass the second check point of the track, the emulation it doesn't even get close (MAME 0.198). MAME 0.196 near the second check point two white racing cars get in the way. - During gameplay at the "Big Forest" track, near the corners if there are two or more computer cars, they always crash at it. - The racing track got very unstable, it shakes too much in 0.198, 0.196 is much more stable. |

| Steps To Reproduce | Watch attract mode or play the game at the Big Forest track. | ||||

Arcade and MAME 0.198 Traffic cars always crash at the the corner and get in the player way, notice the crash and tire screeching sound. The traffic cars don't crash at the corner in MAME 0.196 |

I think you've covered this pretty well. Given it locks up at trying to display polygons for me, something is definitely wrong. |

fwiw I've had Virtua Fighter 2 fail to display polygons once or twice too when just left in attract after startup, so might be something uninitialized in the TGP core as that is a random behavior and probably not related to this bug. the car movement issues are clear to see from the moment the player car incorrectly cuts across the grass at the 10 second mark in the video anyway. maybe it would possible to add some logging code to intercept TGP commands and show their results, to find out which ones are giving significantly different values with the new core vs old core? I imagine OG had a plan for it anyway tho. |

The no polygons turned out to be outdated TGP ROMs, so my error there, sorry. |

I'm going to return to this bug and confirm that this is related to 06861 but not a duplicate. This behavior currently happens despite the updated TGP roms but only in Virtua Racing and Formula. I'm starting to think this is a TGP/CPU issue causing both a bad camera tracking (06861) and the car accelerating faster than usual in attract. Interestingly when running in a linked setup, of two players at least, the slave machine won't have that TGP issue as much compared to the master machine in attract mode. Idk what would happen with more than two players. |
