This is how I gutted my already modified old Thrustmaster F-16 FLCS joystick of my ViperPit and made it work again with the help of an Arduino Pro Micro. This flight stick (and also the other peripherals) do belong in a museum but where's the fun in that? I modified it and now it's a generic USB joystick that works on any recent system. I focus mostly on the 5x5 button matrix since this is the hardest part to understand. In the end are a few minutes of playing X4 Foundations with it to give it a good test run. Now it just needs some oil for the creaking 😅
