I I think what he's saying is that, with the video dumped from the laserdisc in original quality and frame order, one can use WinUAE to emulate the actual arcade hardware (which is essentially a customised Amiga). Admittedly in this case it would be vertical video, but it would work.
Marbella vice, Platoon and Zorton Brothers/ Los Justicieros are all modded versions of the Amiga based ALG hardware, so in theory further development could run those too.
While this Fast Draw release is appreciated, the Digital Leisure code isn't 100% arcade accurate, so a full laserdisc video with UAE would be a heck of a lot closer.
