Hello.

I have two of these bad boys called Logitech ThunderPad G-YA ARC2

I'd like to use them on my PC. I think that they use gameport, but I don't want to order gameport to USB adapter. I want to make it myself

Any help, schematics or anything to direct me?

Probably a lot cheaper just to buy one
