To use above part download and rename extension to a ZIP file and extract the library.
Where did you buy your joystick? I had seen them on ebay as replacement parts for PSP, but they were too expensive. There’s also an BlackBerry, scroll pointer, but none of theme are in bulk (again bit expensive to buy one or two)
Best regards
Have you checked sparkfun ? i think i got mines from there or ebay
