Wineskin is a tool used to make wrappers to run Windows software on Mac OS X. The wrappers are in the form of a normal Mac Application, which can be double clicked and ran just like its native. They can also be used to make a distributable port of software. You do not need the Windows program's source code, you can attempt to port any program you want.
With Wineskin Pro you will receive basic support for installing and configuring the Wineskin Application. We will also answer questions about installing engines and configuring wrappers, and in the near future provide custom engines that have been tested to work with today's most popular Games.
Unlike other solutions you can have multiple engines (Wine versions) installed at one time, so if your favorite game runs in that engine you don't have to worry about it breaking in a future Wine release.
