SheepShaver is an Open Source PowerPC MacOS run-time environment. That is, it enables you to run PowerPC Classic MacOS software on your computer, even if you are using a different operating system. However, you still need a copy of MacOS and a PowerMacintosh ROM image to use this program.
If you are using a PowerPC-based system, applications will run at native speeds (i.e. without any emulation involved). On other systems, SheepShaver provides the first PowerPC G4 emulator, though without MMU, to enable the execution of MacOS Classic. Performance with the current CPU emulator using basic just-in-time (JIT) translation techniques is roughly 1/8-th of native speeds.
Here are some key features of "SheepShaver":
PowerPC G4 emulation on non-PowerPC platforms, direct execution otherwise
Basic but portable JIT engine (x86, x86_64, mips)
Copy and paste of text between MacOS and the host OS
File exchange with the host OS via a Unix icon on the Mac desktop
Color video display with support for run-time resolution switching
Run-time depth switching from 1 bpp to current host depth settings
Native QuickDraw 2D acceleration for BitBlt and FillRect operations
CD-quality stereo sound output
Networking: SheepShaver supports Internet and LAN networking via Ethernet and PPP with all Open Transport compatible MacOS applications.
