OSX - Retro-Bit Tribute64 Dongle phantom inputs

[retropieuser]

The bug can be seen in this video, once the Retro-bit tribute64 dongle is plugged in, phantom inputs begin on loop (https://youtu.be/IfKAnqhvloo)

As a result unable to map anything for this controller and use a tribute64 controller on the Mac version of Retroarch. This affects 1.10 and 1.12 on both the Metal and Intel version (using an 8gb M1 MacBook Air)

Edit:- One factor I notice. When trying to use the controller on AetherSX2 or Dolphin, there's an HID input and an SDL input. If I select the HID it causes the phantom inputs. Is there a way to add SDL to the controller driver on Mac Intel or Metal versions? Or I would need to build this manually myself?

Another edit:-

So MFI Driver was added, this just gives us nothing in terms of device

If HID driver is chosen, controller goes haywire as before

Okay just to add have been able to get Retroarch Intel and Metal building using Xcode. Which DHAVE cflags would I need to add to get SDL controller input driver? As Mac by default only builds with HID. This would solve my controller issue I think

It happens also with Pro Controllers. It seems a phantom up or down button is pressed.

A very inelegant solution but I downloaded the gamepad mapper app from the apple app store and just mapped the controller's SDL presses to keyboard keys. That fixed the issue and if I keep that app open I can use the controller, not particularly elegant solution but at least it works at all
