binjnes vs My NES

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.

My NES is a portable, open-source NES and Famicom emulator for Windows, written in C#. It emulates NES processing, supports NTSC, PALB and DENDY formats, and implements about 97% of known documented mappers. The project says it passes most known hardware behavior tests, although some games may fail because of an unimplemented mapper or emulation bug. A built-in launcher organizes games, shows information from NesCart DB, and records ratings and play time. Users can save and load states, take snapshots, record game audio and use Game Genie. Four-player joypads work through a keyboard, joystick or Xbox 360 controller. Video can be upscaled beyond Full HD. The emulator is multithreaded, and the project reports 60 fps on older Windows machines. My NES is.NET freeware under GNU GPL version 3, listed at free. It usually runs after extracting a portable package and stores settings and user files in Documents. Requirements include.NET Framework 4, DirectX and Microsoft C++ Runtime.
