Looks like an improperly-emulated effect. |

Needs regression version, it's currently running HINTs outside display area. fwiw doesn't happen in teradrive. |

https://github.com/mamedev/mame/commit/a114d0643a92d9e96e64a5cfd0e99dcbdf5a013c Doesn't happen on Teradrive because I made sure to not trigger HINT when out of the active scan area, as explained by https://jsgroth.dev/blog/posts/emulator-bugs-fatal-rewind/#background-vdp-interrupts Guarding the HINT section with:
if (get_scanline_counter() == m_irq6_scanline)
{
// osd_printf_debug("x %d", get_scanline_counter());
m_irq6_on_timer->adjust(attotime::from_ticks(32, clock() / 4));
m_irq6_pending = 1;
m_vblank_flag = 1;
}
// TODO: V30 mode (PAL) runs the V counter up to 240
if (get_scanline_counter() <= 224 && !m_vblank_flag)
fixes this. |

goldnax3 intro desync is a separate issue, but logging in hash file. (was like that in MAME 0.273 as well) |
