Rosalie's Mupen GUI

Rosalie’s Mupen GUI, usually shortened to RMG, is a Nintendo 64 emulator developed by Rosalie Wanders. It is a front-end written in C++ with Qt that wraps the mupen64plus emulation core, with the aim of making mupen64plus simple to set up and use.

RMG bundles a choice of plugins: GLideN64, Angrylion-Plus and parallel-RDP for video, and HLE, cxd4 and parallel-RSP for the RSP. It has a game list with cover art, its own input configuration screen with controller mapping, and netplay through a separate server program that players can host themselves.

Official builds are released for Windows, as a portable zip or an installer, and for Linux as an AppImage. It is also available on Flathub. RMG is licensed under the GNU GPL version 3 and is actively developed.
