Oh wait, I figured out.....Welp, any newbies that don't know..Here is what you do: Right click RCT3 in your library, go down and click Properties. Then press Local Files and then click Browse Local Files. From then the icon of RCT3 should open up in Finder. When that happens, right click the icon, click Show Package Contents, then click Contents, then GameData, and you can find Style from there!
I hope you newbies out there find this useful!
