Emulator Problem: Problem using a twin PS2 to USB adaptor with nestopia.

I can't get it to work. When I set the buttons, it recognizes the second pad and designates it joy 1 even, but in a game it doesn't work. Only player one moves. Drivers and everything are installed. Help?

Nvm, I got it. Just so anyone's wondering, I went into the Machine tab then Input and set both pad1 and pad2 to port 1 and that fixed it. It had auto selected to put pad2 with port 2.
