Hello all. I am wondering, as Im needing a 2nd AES controller, if I can just hack a regular controller to the DB15 connector via the pin map out on GameSX
http://www.gamesx.com/controldata/neocont.htm

I tried doing some of it but what happened was the DB15 connector was way not deep enough to reach the pins in the AES and so I started hacking away around it and now I dont know if its making contact or if the buttons are just not working cause of the common (ground) should be the 5v+ connection instead. I would hate to fry my expensive system. Any feedback would be greatful
