Testing needed with following setup: CV64/3D (or any already emulated RTG board) + CGX + and demo XIII (
https://www.pouet.net/prod.php?which=4389).
Does it run smoothly in any (real) setup when using Cybergraphics option? At least CGX4 version I have does not seem to handle VGA vsync interrupt correctly which results in long pauses between frames. Picasso96 works fine.
If it works (both real and emulated): which WB/KS/CGX combination?
EDIT: demo needs 320x240x8 resolution.
