HOW-TO: Play Project 1999 on a Mac

[camdog]

It looks like with Catalina the default shell has been changed to zsh instead of bash. The Wineskin package I've been running must use bash and when I run it throws a message about zsh. It looks like it's possible to change the overall default shell back to bash and I think it might run but I'm wary of changing basic settings on my Mac to run this game. Anyone have any thoughts? Would the correct approach be for a Catalina version of Wineskin-EQ be made using zsh?
