Request: BS-500AS Terminator 2 Console Gamepad Pinout

[warwolf]

Hi,
I'm working on a project that requires using a NES gamepad.
Unfortunately, all I could find in my area were some Terminator 2 gamepads.

The console is known as BS-500 AS or Terminator 2 or Ending-Man.

As a reference, I found this: http://www.bulforums.com/sandacite/viewtopic.php?f=17&t=5816 , but unfortunately, it's a dead end.

I would appreciate any help any one of you could give.
Thank you.
