Well, I bought this $13 USB gamepad from Newegg http://www.newegg.com/Product/Product.aspx?Item=N82E16826249041
and I think it's either defective or not compatible. I launched a few different games and get the same result. Basically its as if I pushing left on the D-Pad and the jump button at the same time when I play any fighting games (example: Mortal Kombat or Streetfighter II). I read the wiki and I checked the Mapping on the controller. Everything seems to check out. Any other tips or hints before I replace this game pad with another brand?
