After Upgrade from 3.2 to 3.3, N64 controls don't work

Hi All,

I performed the upgrade using the Retropie menu and it seemed to go fine. Everything still works, but I noticed that the N64 emulator has changed to default to Mupen64PLus. The website says that this emulator will autoconfigure controls when I do the initial setup in Emulation Station, however it didn’t seem to work.

After the upgrade, Emulation Station did make me redo the controller configuration which I did, and it works in all RetroArch emulators. But no controls work at all in the Mupen64PLus. What is the easiest way to get this working?

I’m using a Raspberry Pie 2 with an ipac2 controller which just acts like a keyboard.

Any help is greatly appreciated, I hope I’m not just missing some obvious NOOB thing. Thanks!!
