you was not wrong, you just need to be carefull when you add new hardware revision
support as the code was add for precedent hardware and you will need it to bisect it.

I've seen this kind of problem too much to not be carefull as you can have to
pass hours maybe days to debug it

as you confirm you do not brake the old hardware support
just take a look to not loose the "game button" as the analog controller is
not even availlable

otherwise fine
