PS2 port on my MAS won't read

I have a PS2/DC/Saturn MAS and for some reason, the PS2 port won’t work at all. All the wires seems connected and the DC/Saturn ports work perfect. I sent an e-mail to Massystems and they still haven’t responded. Is there any specific problem on this port alone in this condition?

Hey! Didn’t you buy this stick through me? Drop me an email via my website and I’ll see what I can do to facilitate this for you.
