OK I managed to get it working somewhat on WinUAE and FS-UAE using and Picasso IV 4MB.. I will troubleshoot to see what exactly caused that line error.
The game plays in a screen in the background but there is a black Hollywood window in front that is annoying.. I will be trying parameters to get rid of that window as it seems unnecessary for the game.

Finished troubleshooting:
Any configuration with less than 128MB RAM starts to give errors on creating screens (Line 27 and other errors).
Requires resolutions of a minimum 640x480 Hi-Color 16bit or True Color 24bit
The annoying black Hollywood screen keeps reappearing in the foreground blocking the view with total blackness, can just click randomly outside to hide it again, but clicking anywhere other than the cards makes it reappear.. so I am looking in how to get rid of it permanently.
