--- Comment #8 from blubban@gmail.com --- Dropping that patch is fine, it just adds some tests to ensure future Wine development doesn't break anything. It doesn't affect the game itself. (I'm not sure why you're using not-Git for Git patches, but none of my business.)
Looks like I managed to break 16bit pixel formats; Wine's CI caught that just before you posted. Fixed, please retry. Sorry about that, I should've run more tests locally.
Let's hope that was the last broken piece.
