Issues when adding Second Controller in Retroarch

[earthprime]

I'm trying to setup a second controller for multiplayer in Retroarch - a generic USB N64 controller.  Both controllers are the same, and Retroarch recognizes each controller instantly once connected (I get the little left-hand notification that a controller is now active).  I go to INPUT > PORT 1 BINDS  and configure the first controller.  I go to INPUT > PORT 2 BINDS and configure the second controller.  I load an N64 multiplayer game, like Wavewave or Goldeneye, and discover that only ONE controller works and moves BOTH players at the same time.  I then tested by using an Xbox One controller as Player 1, and the N64 USB controller as player 2, and the same thing happened again (primary Xbox controller was moving both players).  Very confusing ... am hoping someone else might recognize where I've gone wrong.

Switching to a different CORE resolved my issue.  It clearly showed the Xbox controller was mapped to the input of Port1 and 2.

That’s odd since most cores should all be using the abstracted Retropad interface and be the same.

Which cores were you using and which did you switch to?

Is it possible that you had an old core, or directory, or game override that was changing the settings?

I was using the Parallel CORE, and the config folder is empty (so no overrides).  I'm going to uninstall all N64 cores and re-install to re-test - its probably something with my config somewhere and a fresh CORE install should resolve.

Core settings and controller remaps are not saved to the core, so redownloading it wont change anything. They are saved in the retroarch.cfg or in the config folder.

This must have been user error on my part - I setup the parallel CORE again and it worked perfect with two N64 controllers.  Honestly can't explain it, but def. user error.

Do you have any guidance on how to easily NULL controller inputs?  Goldeneye was playing like a dream until I discovered (when opening in-game doors) that the ACTION and WEAPON buttons were both triggering together.  Scratching my head again, I realized that Retroarch pre-populated duplicate-inputs for some keys the N64 controller doesn't have (such as X and Y) and I think this is whats messing me up (i.e. two input buttons mapped to the same function).
