Hi rcs300, thanks! You are asking for Jnes? This is a thread about the website
I'll move this later
Adding X-Input support to Jnes is complicated by the fact that it does not support keyboards and most consumer game-pads, it's not a replacement for Direct Input. Supporting X-Input for just a handful of devices I don't have access to hasn't been that attractive to me. Additionally Jnes still supports Windows XP, and X-Input support seems sketchy there.
This delicate situation has caused me to ignore X-Input, and many applications have done the same. Sorry to hear that your controller does not work, I'll add X-Input to the wish list for a future release and see what I can do. If you are looking to make a donation to help fund X-Input you can find a link on the downloads page.
