I have this doubt the joystick xcsource will runs under MorphOS?
Fo example this:
https://www.amazon.es/XCSOURCE%C2%AE-Joystick-codificador-Fighting-AC549/dp/B01M59KT4N
To run MorphOS game and console emulators, MAME, etc.
In theory this device is as simple as an old Amiga joystick.

Assuming it's a HID compliant joystick there is no reason for it not to work.

Well, only I shall buy the components to make the joystick and test it under MorphOS.

Let me know if you have any problems setting it up...

I found a good joystick to play under MorphOS the MayFlash F500 see here: http://www.mayflash.com/Index.html
I play to several gamesw as 1941 Deluxe, Hurrican and MiniSlut and works fine with others not is better the keyboard, curiosly this joystick doesn't work under OS4, it isn't recognize for the system, I can't play to MACE with it, or that some day we have a MorphOS version.
