SheepShaver

PowerPC environment/emulation for Classic Mac OS (SheepShaver). It covers the machine: Macintosh.

1. Installation

1. Download the latest version from the project's official website.
2. Extract the archive into a dedicated folder.
3. Launch it once: it will create its configuration and subfolders.

2. System Files

This emulator relies on files taken from the original machine. Extract them from hardware you own.

Files expected according to our sheet:

• mac.rom

Indicated location: /bios/mac/

PowerPC Mac ROM required + Mac OS 8 or 9 disk image. Must be dumped from a real Power Macintosh.

3. Supported Formats

.dsk .img .hfv .iso

4. Good to know

• These machines often boot to a command prompt: the game is launched via a command, not a menu.
• Emulation speed matters: too fast and the software becomes unplayable. Look for the speed or cycles setting.
• The keyboard is the main input device; the emulated layout may differ from yours.

5. Not working?

• Won't start or black screen → a system file is missing, misnamed, or not in the expected location.
• File rejected → its checksum doesn't match the expected one; the dump is probably incomplete or from a different model.
• The game doesn't appear → check that its extension is among the formats listed above.
• The software runs too fast or too slow → adjust the emulation speed before anything else.
