Unable to map R, Z and C-left C-right buttons on N64 controller

[williamccrobinson]

• I have checked the known issues and searched Github to ensure this issue has not already been reported.
• This is not a feature request, I know those belong on Discord/Github Discussions.

Description of the bug:

I am using a N64 controller via Raphnet USB adapter. The controller is detected by Starship and I am able to map almost all buttons except:

• R
• Z
• left C
• right C

When I attempt to map them, the button presses are not detected. I need to hit "cancel" on the button press dialog in order to proceed. All other buttons not listed above map and behave properly.

Can you reproduce? If so please list the steps:

• No, I cannot reproduce this bug
• Yes, here are the steps to reproduce the bug:
• Build fresh linux build of v1.0.0
• Open the controller mapping dialog and attempt to map R, Z or left/right C buttons

System Information:

• OS: Arch Linux (6.12.4-arch1-1)
• GFX Backend: OpenGL
• Game: Starship
• ROM: Star Fox 64 USA 1.1 revA

Additional information

The controller shows up as raphnet technologies Dual GC/N64 to USB v3.6 when using sdl2-jstest --test 0. All buttons are showing as working when testing in sdl2-jstest.
