Is there an easy way to install a turbo button for playing emulated games, on Windows 7, with joypad?
Many joypad devices come with a button that is called Turbo just like in these cases where a user requires rapid fire or movement. If the joypad belongs to a known company which produces these devices you will surely have configuration software which allows you to do that. Another solution is to simply use JoyToKey and choose the button you want to do what you need and also when it’s pressed to act as a Turbo button by setting what button should be emulated then by adjusting the rates. I have attached an image with a given example.
