Is there any easy way to make your own controller ?
I mean
- make any game detect it like a 6buttons controller (ID)
- handle TL/TH
- ...
So already available kit to just connect your buttons

I was about to buy a very cheap Joy6 controler frol AliExpress and hack it but if I could make something open, it will be a lot better for anyone who want to do the same...
