You don't need any other components for you converter. Just wire any retro joystick directly to its GPIO and write the firmware
No need to write the firmware, this guy already did it (partially):https://github.com/mcgurk/Arduino-USB-H ... ickAdapter
I've checked this ... the code itself isn't working (anymore) due to an update of the Joystick Lib ..... and I personally don't like the flying leads to the Joystick connectors and ... and ... and ....
So I've played a little bit (having some Pro Micro clones laying around) ....
I've started for now with DB9 for Atari Joysticks (Competition Pro Retro) (that have also the possibility to have 3 Buttons (Atari ST / Amiga) .... I've a modified one with 3 button support
Output from my side:
A small PCB (KiCAD) for 2xDB9 and one Arduino Pro Micro wired for 3 Button support on both DB9
Pro Micro FW adopted to this PCB.
As I'm not allowed to attach any files - I've uploaded the stuff to dropbox https://www.dropbox.com/s/ekqlb35r581zg5q/USB2DB9.zip?dl=0
At the moment I can't gurantee that everything is working as expected as I've not received any PCBs till now (and this will take at least 2 weeks (epacket to Germany)
