So, I'm right and JuanLeOnardO too For GC controller, this will cause no problem because it's a native behavior, but for non nintendo controler, it could cause trouble... It seems to be what JuanLeOnardO saw with his tests.You didn't find anything because there's no sensitivity setting.
Currently Nintendont reads the value provided by the HID-USB and send it to the game.
We will see in future updates if we can add more options to controller.ini
We have few ideas to implement but it's not a high priority.
Could you point us where the "forward" is done ?http://gbatemp.net/members/juanleonardo.347391/
