Installation and setup (All builds/versions)
If you have an existing SheepShaver setup, you can simply replace the application with the new application.
If you set up SheepShaver for the first time, you will also need a compatible ROM file and a retail MacOS install CD (or an install CD disk image).
For other than US English keyboard layouts a keycodes file is needed.
The SheepShaver Scripts can be used to delete the prefs and nvram files to be able to start a new setup from scratch.
