"Joystick Right" is recognized as 3 separate inputs

[pgathriller]

Here's a weird one:

When I move either of my arcade controller's Joysticks 'Right', MAME suddenly began recognizing this movement as 3 different inputs

Attached a video of me assigning controls in MAME; as you can see, moving the joystick applies 3 separate inputs bundled together into MAME

For more context, I'm using RetroArch to launch my emulators

 

Which leads me to believe this is somehow an issue with RetroArch as running a standalone version of MAME, outside of RetroArch, seems to have no issue assigning inputs properly

To be honest i would just recommend using standalone MAME. MAME in retroarch can be a bit of a nightmare especially when it comes to controls, as you have discovered, you have retroarch itselfs controls, and then the MAME tab menu controls competing with each other for control. I use retroarch when i can, but i actively avoid it for MAME.
