Hi Thank you for your reply. I can clarifying about the encoders/controllers, they popups as a normal usbcontroller in Windows, so its no programming software for them, for example in Mame, when i configure the joystick and buttons, so for player1 the joystick will get joy1 up, down, left, right, for the buttons, joy1 button 1, joy1 button 2, joy1 button 3 and so on, player2 will get joy2 up, down, left, right, for the buttons, joy2 button 1, joy2 button 2, joy2 button 3 and so on and the third one get joy3 for the buttons, joy3 button 1, joy3 button 2, joy3 button 3 and so on. So I was thinking if it possible to get same function in Gameex, so when configure those buttons it will get joy3 and then knows that only those button works and not the buttons on joy1 and two 2?
