This is actually already known, from https://github.com/mamedev/mame/issues/12483 However, Mametesters is the best place for this report, so I'll ask the devs to close the issue. The notes from the issue: Osso said: Confirmed, regression version seems to be 0.254 Suspect commit: https://git.redump.net/mame/commit/?id=c0b57d30f0ce39c445190fe4e27bec6c57ebb137 Kale said: Reset isn't caused by watchdog, but rather an intentional snippet where it expects: 3C80: cp $95 ; from $8063 RAM buffer 3C82: jp nz,$0000 0000: ld a,$10 0002: ld ($7100),a Game eventually boots anyway (at least by speeding emu up here), but somehow this is 0x05 the first time around. |

OK Robbbert, I didn't check MAMEDev's GitHub because honestly, never thought to search there first. I always had MAMETesters in mind for bug reporting ;) |

Hi, I would like to add the following observation to the bug description: If the file "sxevious.hi" does not exist in hiscore folder, sxevious reboots three to four times. If the file exists, only a single reboot occurs. |

I was fiddling with the timing. I tried to make the namco06 clock like this: -_-_-_-_ instead of _-_-_-_- And that fixed the sxevious issue. But it (re)introduces explosion/shot sound bugs in bosco. And tweaking quantum in galaga.cpp makes it worse? That's not a good sign. It's so sensitive. So, scrap that. Also, I changed bug severity from critital to major. It's a pain to have to wait for the bootup, but if your finger finds the INS key, the game itself works fine. |
