I was hit again by the retro. The USB PC game pad seems to be inspired from the 16-bit Nintendo Super NES in the 90s.
The USB PC game pad measures 144 x 63 x 25mm, and comes with a 1.8m connection cable. As same as the Super NES controller, the USB game pad features 8 buttons.
USB Nintendo Super NES PC Game Pad can be available for about $30 USD at GeekStuff4U. Two colors can be selected. Moreover, if you prefer more ancient game pad, you should check out the 8-bit Famicon USB game pad.
