NetOne, thanks for the explanation!
I'm familiar with the x360ce software, but it doesn't work with html5 games.
I found another generic Bluetooth gamepad, it's not that old (about 4 years), but it too has the same issue with the right stick.
So now I have three different gamepads with the same problem...
I tried RawAxis expression and it does read Right Stick Y position. Axis number is 5.
So I'm still confused - whose fault is it that filtered input from the right stick doesn't work in Chrome?
Is it because Scirra didn't implement dinput method, or because Chrome doesn't support it?
STARTECHSTUDIOS, what gamepad model do you have?
