m64p (2020/10/18) 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:
Apologies for the back-to-back releases. As mentioned, a large amount of the underlying GUI code has been re-written. I found some last minute bugs that are addressed in this release. No reason to upgrade if you aren't having issues with the GUI
Known Issues: Sometimes the emulator will crash when launching a game in Windows. As best I can tell this seems to be a bug related to Qt. I'm hoping the next minor release of Qt will address the issue, if it doesn't I'll need to come up with an alternative solution.
