Play Princess Toadstool's Castle Run Game on Mac with Parallels (virtualized)

The easiest way to play Princess Toadstool's Castle Run Game on a Mac is through Parallels, which allows you to virtualize a Windows machine on Macs. The setup is very easy and it works for Apple Silicon Macs as well as for older Intel-based Macs.

Parallels supports the latest version of DirectX and OpenGL, allowing you to play the latest PC games on any Mac. The latest version of DirectX is up to 20% faster.

Our favorite feature of Parallels Desktop is that when you turn off your virtual machine, all the unused disk space gets returned to your main OS, thus minimizing resource waste (which used to be a problem with virtualization).
