Well I've only tried RCT2 so far but the first game should be the same.

Just follow this guide - http://www.thomasboyt.com/extras/rctmac.html

And you don't even need the Windowed mode hack, just set Wineskin to windowed mode.

I've gotten it running fine in Wine but I've run into just one game breaking glitch: you cannot delete scenery. Right click doesn't work and without that any piece of scenery you place becomes unremovable as does the scenery that starts on the map.

Do you mean you can't right click at all? I've just tried and I can remove scenery with the right click, and also the demolish tool as well?

Which version of Wine are you using?

I'm using Wineskin Winery v1.7 with engine WS9Wine1.7.23 and Wineskin v2.6.0.

EDIT: Oh I just saw your other thread. Looks like you didn't have right mouse click on Mac setup. I'm using a regular two button mouse without problems.

Has anyone tested this with RCT3?
