Myself and other users have noticed that when we are using the Keyrah, there are certain joystick combinations that will not work when two players are using joysticks simultaneously. We're wondering if this is a limitation of the way USB keys work or if there is something that can be done to fix it.
In emu mode (switch down), if you hold DOWN + LEFT on JS2 (JS2 DOWN=Keypad 2, then JS2 LEFT=Keypad 4) then try to push JS1 RIGHT=Keypad 1 on the other joystick, it will not register. There are other combinations as well that prevent FIRE on one joystick while holding DOWN+RIGHT or UP+RIGHT on the other. The issue has been reproduced on Linux, Windows, Raspbian and BMC64. Same type of issue will happen with 'normal' mode (switch up) just different combinations. Is this generally a limitation of using usb key events for joysticks? Thanks.
