m64p (2021/06/13) 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:
A couple of minor emulation accuracy improvements for PI and RSP DMAs. I'm not aware of any impact on games.
Widescreen support (you'll find it in the ParaLLEl Video options). This is the equivalent of setting your TV to "force 16:9". This would normally be used on a game like GoldenEye, which has a widescreen option in the pause menu. Using this on a regular 4:3 game is just going to stretch the image.
