Description
If you have a dedicated spinner, you can't assign buttons on the "controller" as the "mouse click 1&2", only the device mouse clicks work.
The spinners have their own decoders (USB).
With the MAME core you can just assign any input function to any controller device, so no issue there. But every other core is "broken" in this regard.
Can't use physical spinners with player buttons due to having no way to map these game inputs to something other than device ID mouse click.

Something like this would make spinners work for PS1, SNES, NES and Master System paddle games.

Research direction
Start by comparing RetroArch's controller-device mapping with the MAME core behavior described in the issue, focusing on how spinner and trackball clicks reach non-MAME cores. Define the supported mapping behavior for PS1, SNES, NES, and Master System paddle games, and verify that physical spinner buttons can be assigned to the required player inputs.
