Mupen64Plus vs Wii64 / Cube64

Mupen64Plus is a free, plugin-based Nintendo 64 emulator for Linux, macOS, Windows, and FreeBSD. It is designed to play many games and includes four MIPS R4300 CPU emulators, with dynamic recompilers for 32-bit x86 and 64-bit amd64 systems. Plugins cover audio, graphics, signal co-processing, and input. Listed features include two OpenGL video plugins with high-resolution texture support, Rumble Pak and LIRC infrared remote support, and a GameShark-compatible cheat system. Users can adjust speed while retaining smooth sound output. A shared library interface allows integration with other systems and front-ends. The distributed download bundle includes a command-line-only console front-end; the project points users to third-party front-ends for graphical options. The v2.6.0 release page lists prebuilt 64-bit downloads for Linux, Windows, and macOS, plus source code. Documentation covers setup, file locations, rumble, textures, compatibility, and core and plugin settings.
