Mupen64plus controller config help

Hi everyone,
First of all the Mupen64plus emulator works flawlessly on my machine; however, I am having issues using my Xbox 360 controller, it works, it’s just mapped weird. Unlike the Snes9 emulator there is no GUI to configure my preferences. Any help or suggestions would be appreciated.
On a side note, the community here is fantastic and the Devs have done a great job!

Never mind I fixed it. I installed Mupen64plus natively and made that the primary emulator for Lutris. Then I installed M6PY which solved the issue.

We’re going to drop mupen64, it doesn’t run that great. Instead we will rely on the version provided by libretto (which is already available in lutris)
