Assuming it doesn't take button presses in its input configuration (where you go to set keys), I assume something like Xpadder would work; it just maps different keys on your keyboard to buttons on your gamepad. A freeware version can be found here, though this copy in particular needs to be run in compatibility mode (right click xpadder.exe, click Properties, click Compatibility tab, check "Run this program in compatibility mode for" and select a Vista or XP option, click Ok and run it). I haven't personally tried this on Win8 but there's no reason it shouldn't work AFAIK.
It can be a bit tricky to set up if you've never used it before, but there are tons of guides out there that should get you started.
"I think that the problem with this video is it is highly derivative of many popular bands within the genre. Although when viewed on its own merits, it does have a deeper groove. However what it has in groove, it lacks in originality. One can't help but be reminded of such bands as Pearl Jam, White Zombie, Suicidal Tendencies and other bands that bear the mantle of so called "Alternative Rock". One is even reminded of Lorie Anderson when she wore curlers. Hehehmhm! This video speaks less to the heart and more to the sphincter. In closing, I think Korn would do well to learn more from -"
