GSSquared

A complete Apple II series emulator

Apple II, Apple IIe, and Apple IIgs emulation in one app. Cross-platform. Simple, intuitive UI — packaged 100% ready to go.

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.
