L3 and R3 outputs swapped when emulating a Switch Pro Controller

[Artic252]

Describe the bug
When setting the adapter to emulate a Switch Pro Controller, L3 and R3 inputs are swapped (Pressing L3 on the controller will cause the adapter to output R3 and vice versa). I found the bug when using my DualSense and I was able to replicate it also when using my Switch Pro Controller.

What type of controller do you have the issue with?
DualSense (VID_054C | PID_0CE6)
Switch Pro Controller (VID_057E | PID_2009)

What platform are you using the OGX-Mini on?
Switch, PC

What board are you using?
Adafruit Feather RP2040 with USB Type A Host

I did a manual build to see if I could fix it myself and I found it is fixable by changing:

if (gp_in.buttons & gamepad.MAP_BUTTON_L3) out.buttons[1] |= SwitchPro::Btn::L3;
if (gp_in.buttons & gamepad.MAP_BUTTON_R3) out.buttons[1] |= SwitchPro::Btn::R3;

to:

if (gp_in.buttons & gamepad.MAP_BUTTON_L3) out.buttons[1] |= SwitchPro::Btn::R3;
if (gp_in.buttons & gamepad.MAP_BUTTON_R3) out.buttons[1] |= SwitchPro::Btn::L3;

in:

\OGX-Mini-2026\Firmware\RP2040\src\USBDevice\DeviceDriver\Switch\Switch.cpp (lines 99 & 100)

I'll find out why it's actually swapping the inputs because just changing those two lines will swap it backwards for everyone else.
