Does anyone have any experience making this work? I have the software alonside with my copy of Marvel vs. Capcom 2, but not sure what additional stuff I need to get the joystick to work. I heard I might have to get NullDC version 1.6… outside of that can anyone help me to get this working? Again, game functions fine, just need help setting up Standard Edition stick as input device.
Might need to use Joy2Key as some versions of NullDC only have keyboard support.
google xpadder, should do the trick
Joy2key works fine, just map your joystick to numpad keys or something. However when running mvc2 on nulldc for some reason whenever i hit left on the joystick, the screen slows down a bit and these black lines flash on and off screen anyone else have this problem?

click on the sf stick
then go to config your keys
click once then tap or push the key you want easy 
is yours for the 360 or ps3?
im having trouble detecting it for my ps3
mines 360 urm ive read somewhere you had to download a driver for ps3 not sure yet
you have to have the nulldc joystick plugin. it comes with 1.0 beta 1.6
Finally got it all to work a little while back. I can’t really say what I did in the end, I just messed with a bunch of the nulldc settings (joystick related and not) until it ran smooth and the buttons all worked. The biggest problem was no having the correct nulldc version. The one mentioned earlier in this post by another user is the ONLY one with the joystick ability. Without getting that particular one you are boned.
joystick problem fixed! 
ok, download nulldc 1.0.4, grab the puru puru.dll file out of it and put it in nulldc 1.0.0 beta 1.6 and u’ll b fine
