What makes GSSquared different

Three design goals

These are the characteristics that make GSSquared unique among Apple II emulators.

  • 8-bit and 16-bit together

    Support for both classic Apple II and Apple IIe machines and the Apple IIgs — to our knowledge, the only emulator besides MAME that models (most of) the 8-bit Apple II line as well as the 16-bit IIgs.

  • Truly cross-platform

    Built to run on macOS, Windows, and Linux — same project, same idea, wherever you work.

  • Ready to run

    A simple, intuitive user interface, packaged 100% ready to go — no hunting down extra downloads just to get started.

GSport, KEGS, GSplus, and Sweet16 are other Apple IIgs emulators. GSSquared runs the IIgs and the 8-bit Apple II, II+, and IIe on Mac, Windows, and Linux, and in the browser.
