Summary
binjnes is a free NES emulator written in C, with a browser version and build-from-source options for Linux and macOS. Its cycle-accurate emulation passes many timing tests, and it supports numerous cartridge mappers through a built-in cartridge database. Additional audio channels are available for mappers 19, 24, and 26. Users can save and load battery backup data and emulator state files, pause, advance one frame, rewind, or seek to a specific cycle. The browser version runs as WebAssembly and lets users upload a file to play. Desktop build instructions use make or CMake; building requires CMake and sokol, while a WebAssembly build also requires Emscripten. A Python test harness validates tests using hashes, and the source code is distributed under the MIT License. The GitHub releases page has no packaged downloads, so desktop users need to build from source. It is available for Linux, macOS, and web use.
Who it is for
binjnes suits NES players who want a browser emulator or are comfortable building software from source on Linux or macOS. Its save, rewind, and frame-stepping controls may appeal to users who want fine-grained playback control.
