What seems to be one of the best ways to get Nintendo 64 emulation on windows has again been updated, heres whats new:

m64p (2017/12/16) 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.
