[RESOLVED] EmulationStation/RetroBat not working with RetroArch Dolphin Core

Hey!

I have been working on a project that allows me to dual boot an SD card into Batocera for Steam Deck and RetroBat for Windows (ROG Ally)

I have managed to get everything working nicely from the same rom/save directory for almost every single emulator apart from the dolphin emulator.

for some reason, when I launch the retroarch dolphin core via the RetroBat/EmulationStation UI it doesn't allow me to use my Xbox 360 Controller for input at all - I don't have this issue when launching RetroArch cores for any other emulation apart from Dolphin.

Things I have tried;

Manually overriding the es_systems.cfg settings for the Dolphin/Gamecube system
Adjusting the "per system settings" for GameCube within EmulationStation - this includes changing the "Autoconfigure Controller" setting to off - the only difference when this is toggled off is I am able to close the game using the start+select hotkey on the controller (showing that the controller input is somewhat being passed through..)

More Key Details;

I am able to control the game via the keyboard when it opens, just not the controller.

When I launch the game via "RetroBat Config > RetroArch > Load Core" it works just fine with full controller input, the issue seems to stem from launching via the EmulationStation UI.

I am only having this issue with GameCube and everything else is working flawlessly across both systems so I would appreciate any suggestions/advice - thank you!

You would need to force driver to xinput for the gamecube, as the core has an issue:

That fixed the problem, thank you!!
