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.
