In their own words
binjnes
binjnes is a free NES emulator written in C, available in a browser or through source builds for Linux and macOS. Its cycle-accurate emulation passes many timing tests and supports numerous cartridge mappers using a built-in cartridge database. Mappers 19, 24, and 26 receive additional audio channels. Playback controls include pausing, advancing one frame, rewinding, and seeking to a specific cycle. Users can save and load battery backup data and emulator state files. The browser version is built as WebAssembly and lets users upload a file to play. Desktop build instructions use make or CMake; building requires CMake and sokol, and the WebAssembly instructions also require Emscripten. The project includes a Python test harness that validates tests with hashes, and the source code is distributed under the MIT License. The GitHub releases page lists no packaged downloads, so desktop users need to build from source.
