RMG (Rosalie's Mupen GUI) is an open-source, plugin-based Mupen64Plus Nintendo 64 emulator frontend maintained by Rosalie241, which is focused on a simplistic, sleek GUI design and pays homage to the look and feel of Project64.

The project aims to close the gap between Project64 and Mupen64Plus regarding user experience. The project was archived on January 9th, 2021, but it opened up again on July 27th, 2021.

RMG supports cheat codes and offers a "grid view" of your games, along with their covers, if you provide the images. Starting from version 0.2.5, it switched from Qt5 to Qt6, providing a sleeker look.


RMG currently includes the following plugins:


  • GLideN64
  • ParaLLEl-RDP
  • Angrylion's RDP Plus


  • Rosalie's Mupen GUI Audio Plugin


  • Raphnetraw Input (for use with real N64 controllers)
  • GC Adapter (for Wii U or Switch) Input
  • Rosalie's Mupen GUI Input


  • Static Interpreter (CXD4)
  • Mupen64Plus HLE RSP
  • ParaLLEl-RSP

It is also compatible with other plugins, like those that come with regular Mupen64Plus, should you wish to use them over the ones mentioned above. However, just like with standalone, you must configure them by editing the mupen64plus.cfg file. All plugins above (except for the RSP plugins) are configurable via the GUI.
