Its definitely a pass through and it works.
The headphone jack on the other hand, does not work.
I wonder if its really a link port so I can hook my sgfx up to an Express and play gimpy two player disasters. lol.
If that is the case, f*ck YES.
If not, i just spent 30$ on a pad with a feature I don't want.
who needs sega pads when you have duo pads. Thats like sitting on a lawn chair instead of a leather sofa.
