Wanted to revisit DK2 but everything about this sucks.

I can't change resolution, can't enable AA, and on top of that, I see that one mission is bugged.

Will GOG ever gonna fix this, is there some way to fix these issues without searching the internet high and low and managing to get nothing done because these guides/fixes are old or don't work for one reason or another?

I hope some one has a comprehensive guide of how to tackle these issues because I'm going crazy trying to figure all this stuff out.

other issues is that creatures struggle with creating lairs, getting paid and eating.

Currently Flame seems the best thing to get DK2 issues fixed.
