Andrew, please use the internal save snapshot option when adding them to reports. After some testing, I can't repo the corruption at the title screen, but am able to get different types of GFX garbage at the select game level screen. |

This bug seems to be partially fixed as of 0.193. Now only the "Game Level" selection screen shows problems, which seem to happen randomly: |

The corruption is still there at the title screen and randomly at the game level select in 0.221. I narrowed down when it first appeared: 0.142. The whatsnew for that cycle indicates some cleanup done on the driver. https://www.mamedev.org/updates/whatsnew_0141u1.txt -Placed full megadrive code in MAME section [David Haywood] -Reorganized megadrive/sms sourcefiles for better sharing between MAME/MESS.

I just discovered that the same graphics glitches are present when loading the game with the Mednafen emulator. |

Just reproduced it by chance, seems very random. https://i.imgur.com/NXvlZDy.jpeg |

The issue at the title screen appears to be resolved. I still see the glitches on the Select Game Level screen after pressing start. They are not random for me, though. They happen every time. https://imgur.com/a/4LLLioa |
