Hey there,
the cavestory snap is going to be discontinued in favor of a new package called nxengine-evo (see the relevant GitHub issue). I’m creating a new package since there doesn’t seem to be an option to rename a snap package (please correct me if I’m wrong).
The about to be discontinued cavestory package was granted autoconnection for the joystick interface:
I’d like to request the same autoconnection for the new nxengine-evo package.
