Confirmed the problem. The car gets stuck and screeching continues many times in a short period of time. |

Related to 06319? Someone should explain the gticlub hack in adc1038.cpp: WRITE_LINE_MEMBER( adc1038_device::clk_write ) // GTI Club doesn't sync on SARS if (m_gticlub_hack) { if (m_clk == 0 && state == 0) { m_cycle = 0; /* notice that m_adr is always < 7! */ m_adc_data = m_input_cb(m_adr); } } |

This bug makes the game very tedious to play since it randomly occurs when turning. I personally believe GTI Club should be demoted to NOT_WORKING because of this bug. It happens alot when I play the game. |

Agreed that this minor bug makes it tedious to play but I don't think it is bad enough to demote the game to NOT_WORKING status |

well if the controls are broken I'm not sure I'd call it a minor bug. |

With some playtesting, I think the controls are fine. It's just whenever the car starts constantly screeching, your car slows down but the game still responds to user input. It is an annoying bug that is for sure! |

Getting 1st place let alone finishing a race on time is a pain in the behind. The only way I could find myself getting out of the constant screeching is colliding with a wall or any other hazards. Even then its random if the bug will stop or not. |

Is this like the handbrake lever analog input was being pressed on its own? |

It probably is caused by the steering because of the DEVICE ERROR (STEERING WHEEL) message that appears when the machine is initializing. |

Device error steering has to do with the unemulated force feedback (controlled via parallel output data bus in sysreg). Bypass this by enabling DIP 4. The gticlub hack is a nasty one and may have to do with improper adc1038 emulation. Commenting out that hack will have gticlub refuse to go ingame but can go into test mode. |

Is the tyre screeching still a problem? Seems ok to me now. |

This issue seems to be fixed as of MAME 0.274. |

Considering the stub device nature of adc1038.cpp and it having a hack for gticlub, I don't believe it to be fixed. https://github.com/mamedev/mame/blob/master/src/devices/machine/adc1038.cpp |

adc1038.cpp hasn't been touched since MAME 0.256, but the bug stopped occurring in MAME 0.274 and later. (Source: tested multiple versions of MAME up to 0.273, and the bug would always occur within the first few corners. Tested 0.274 for several races, bug never occurred.) I believe commit 2a0ae18 is what fixed the bug, since it made several PowerPC recompiler fixes and was merged prior to the release of 0.274. |

Amendment to above comment: they were mostly general UML and DRC backend fixes rather than PowerPC specific. |
