m64p (2020/04/01) is released. m64p uses mupen64plus-gui, a brand new mupen64plus frontend written in Qt5. It supports all thing things you’d expect from a frontend (savestate management, pausing, screenshots, etc..). m64p comes bundled with GLideN64 for the graphics plugin. It should give you the best out-of-the-box experience available for N64 gaming.

m64p changelog:
Now includes the Raphnet Raw Input plugin. You can switch to this input plugin by going to Settings->Plugin and Path Selection
New hashing algorithm (XXH3), should provide some performance improvement
Some foundational things to get closer to being able to boot more homebrew ROMs, but nothing visible yet
