Just keep in mind it's ridiculously complex hardware.
There are double digit instances of the (still unemulated) communication chip that is usually used for multiple cabinets to talk to each other (and the secondary screens on games like Drivers Eyes) presumably just so that PCBs used by this game can talk to each other as well as some pretty complex Namco 3D era hardware that has been doubled up.
The code that was demonstrated a few years ago to support Driver's Eyes sub-screen communication was never even submitted (probably because it was a hack that relied on multiple instances of MAME to work, which isn't how we support these 'single cabinet, multiple stack' cases)
I've looked several times at the driver, and refactored it significantly so that it would be easier for people to work with in the future, but failed to get it to display even the basic 2D parts.
If I'm not mistaken they also use a pair of laserdiscs playing together (different discs for each half of the display?) for the footage, and MAME's Laserdisc video support is not very flexible to say the least as it's a specific hardcoded case (hence why it struggles even with the HLSL & BGFX shaders)
All of this is going to be *very* difficult to emulate, and performance is likely to be dire.
It'll be good to see, if it happens, but set your expectations accordingly. Even with this progress I'd be surprised if we see it in MAME in the next decade.
