Move this folder to the /home/pi folder, and rename it SheepShaver.Raspberry Pi Apple II Emulators Yes, it's true, your Raspberry Pi can be an Apple II. You'll end up with a folder named MacArm which contains 2 files: ppc and SheepShaver. If you have problems with it, report them on the RetroPie GitHub issues page.Download the ARM version of SheepShaver from Novaspirit, and extract to the downloads folder. NOTE: RetroPie is not a part of EmulationStation. This is one of the easiest ways to get your Raspberry Pi ready for some retro gaming goodness. The RetroPie Project provides an easy way to install over 30 different emulators on the Raspberry Pi, using EmulationStation as a front-end.

It is also important at this stage to be running it from a Terminal window so that the program can be exited if this go wrong (which they definitely be in the next couple of steps).SheepShaver's GUI will open, and in here we can set up a drive file to hold our Macintosh files and operating system, and adjust the various options of the emulation. I am unclear as to why this is necessary, but the program seems much more stable when run this way. This will run the CPU clockspeed in the Pi400 at a steady pace instead of scaling up and down as it does on the default On Demand setting.Return to the Terminal window we had opened in step 2, and enter the following command:This will run SheepShaver with admin permissions.

Button and select the 904.iso file (or the Apple Mac OS 9.0.4.iso file if you chose not to rename it)Still in the Volumes tab: set the Unix Root value to /home/pi/Downloads (or somewhere else you might prefer but I found this location the most useful).In the Graphics/Sound tab: set the Window Refresh Rate to 30 Hz, Width to 1024, and Height to 768.In the Memory/Misc tab: set MacOS RAM Size (MB) to 512. In the Size text box type in a reasonable size in megabytes (anything over 200 MB seems reasonable to me - I went with 500 Mb) and give it a name (I used MacHD)Still in the Volumes tab: click the Add. Button and a new Create Hardfile dialog box will open. Then type:To return to the normal terminal prompt. The reason we had to perform this step was to get SheepShaver to write out a prefs file which we can then edit manually to improve this state of affairs.Still in the Terminal window, type the following command to edit this prefs file:(enter the system password (default is raspberry))The first couple of lines in the prefs file will look like this:Scroll down further in the file and verify that both JIT options are set to false.Press CTRL-x and then RETURN to save the file. Return to the Terminal window and type CTRL-c to break the program and close the emulator window. Unfortunately this results in a loop that you can't easily escape.
