m64p (2020/10/25) 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:
This releases contains a fix for some Mayflash adapters. Some of these adapters didn't work properly in the controller profile configuration wizard. Mayflash adapters still won't work with the "Auto" profile, they need a custom profile created.
Also, sometimes the controller profile wizard wouldn't work after playing a game, this has been corrected.
