Selected Test Results (selected in 'Test Results' table below)
Everything works. Just like playing on windows but only in windows mode.
What does not
Fullscreen doesn't work since there's no way to change the game's resolution.
What was not tested
To get the game working properly I recommend installing Xephyr then if you'd like to make it a little easier with shortcuts. You may use my script (https://db.tt/x5vwxu4F) this should help make running games that requires lower bit depths a bit easier. This script runs both Rollercoaster Tycoon 1 & 2 perfectly.
