MAME game name: quartet2a
Full name: Quartet 2 (unprotected)
DIP switch notes: Difficulty set to Hardest, the rest of the settings are default
While I'm still having issues with MAMEHawk TAStudio stability including a bad savestate making a .tasproj file crashing in TAStudio but still playable in movie playback, the playback itself seems to be working perfectly fine for me. Movie sync still seems to hold up, and I can confirm that the moving platforms in stages 15 through 17 are indeed working in this version of Quartet.
