@rhester72 said in joy2key_sdl.py doesn't support my controller:
To make RA happy, I had to hand-configure the controller in Retroarch (GUI) itself and save from there, which produced the "not-normalized" device name in the configuration file.

OK, so the other possibility of a device name mismatch is the configuration being created outside of EmulationStation's scripts - in this case via RetroArch itself. In any case, this kind of setups will hopefully be better supported by joy2key in the future.
