Thank you for your reply, it is conforting to know the tricks are solid. Maybe it will help some retroprogrammed CGA games to appear with more colors and effects.

I have a VGA XT clone (4.77/8 MHz) and an ATI Small Wonder CGA clone board. I will try to bind them together and run Area 5150.

The ATi Small Wonder is not entirely cycle-accurate. When I studied the CGADEMO by Codeblasters, I found that the scroller didn't look entirely correct, because the Small Wonder was slightly slower: https://scalibq.wordpress.com/2014/11/22/cgademo-by-codeblas... It appears to insert a few extra waitstates compared to an IBM card. This may trip up some effects in Area 5150.
