No surprise laser disc game development faltered. A lot of ways to approach it, and not the interest, especially in the last ten years. It started in 2009 with Aaron doing film-resolution conversions, documenting the process on his blog in text and video. Few took up the mantle, let alone with similar standards I think. And MAME's codebase may have developed away from that work, even.
I don't care for the high-res images. I like seeing it in 640x480 on a CRT, with 23fps sources format.

I found this:
https://emulation.gametechwiki.com/index.php/Arcade_LaserDisc_emulatorsHypseus Singe is an SDL3 update to the DAPHNE emulator engine. It includes fixes to many existing Daphne games and supports one game that neither Daphne nor MAME currently support: Stern's Goal to Go.
The reason MAME doesn't emulate many LaserDisc-based systems, is largely due to indecisions regarding the disc preservation method and format. This will hopefully be fixed in the future thanks to the Domesday86 project which employs a combination of specialized hardware and open-source software to preserve the discs in a far more faithful manner than ever before. Raw captures can be converted to playback formats for other emulators (e.g., Hypseus-Singe) using ffmpeg to get the best visual quality.which employs a combination of specialized hardware and open-source software to preserve the discs in a far more faithful manner than ever before.
