Do all 856x based machines, which would include all C128's, display grey dots when updating VICII color registers while they are being displayed? I'm assuming they do. My 8566 equipped C128D definitely does display the grey dots while my 6569 equipped C64 doesn't show them at all. I know the VIC version of Risen From Oblivion puts this "feature" to good use in a couple parts of the demo.
Here's a simple program from www.lemon64.com/forum/viewtopic.php?t=29996 which shows the glitch in action that can be run in either c128 or c64 mode.
