So, I've been wanted to do more gaming on my surface pro, especially using a DS emulator to turn it into a giant Gameboy. However, in order to do this, I'd need some virtual d-pad/buttons to touch (the existing virtual keyboard isn't cut out for gaming).
Ideally this would take the form of a desktop app that creates these controls in a separate window that I could position relative to my game window. does anything like this exist? and if not then is there another way to realize my giant Gameboy dreams?
