I haven't even used gyro since gravity rush on ps4. I regularly forget it's a feature. The one I'm thinking of I gave to my brother but it had 4 extra buttons that I could map to macros and stuff but in the other mode it was only whatever the 8bitdo app allows, and last I tried that doesn't work in linux.
Its really too bad you can't set it to work in any mode on any connection type because that would give it almost full feature parity to the steam controller and having pretty much full configuration ability without needing their app, while coming in the more familiar ergonomic shapes of the 8bitdo product lines.
