That looks like a homemade fight stick. This was (and still is) a common way to get arcade quality controls for console systems. Many times though, inside, you'll find an actual SNES controller with all the buttons soldered to the traces where the carbon pads would go
Edit: chances are thats a multi-console controller board so this could be used with other systems.
