NES Emulators
Alternatives to GoNES
GoNES is a focused NES emulator with several ways to start: select a .nes file, pass a ROM from a terminal, use release downloads, install through Homebrew on macOS, or run the WebAssembly build in a browser. It supports Windows, macOS, Linux, and web browsers, configurable keyboard controls for two players, save-state actions, and command-line options for fullscreen, audio, palettes, debugging, and logging. It is free and open source, but its supported mappers cover 84.34% of official NES games, its GUI still needs menu options, and compiling requires OpenGL development libraries.

Choosing instead of GoNES
An alternative may suit you if you need systems beyond NES, wider mapper coverage, specialized debugging or recording tools, network play, or a different frontend. Check whether your ROM formats and target platforms are supported, whether you need desktop or browser access, and how each handles saves, controllers, and setup. Some choices are work-in-progress projects, while others have explicit limits such as unavailable netplay or save states. GoNES’s free price, broad platform range, and specific NES scope provide the baseline for comparison.
