I’m currently trying to hack a third-party Dreamcast controller (Performance Astropad) but it doesn’t appear to be common ground. Is there a way to wire it so that it functions as a common ground pad so I can use it in a project box?
No way that would be cheaper OR easier than just buying a common ground pad.
why do you need it to function as common ground anyway
Most likely for multi-PCB setups…
I’ve got a Sega DC pad that’s supposed to be common ground, but I’ve read that the triggers lag on it.
Because I’d be connecting to it through a DB25 cable that’s wired for common ground PCB’s.
