pcsx2 movement issues

Ok I popped in my KHII disc and it runs smooth as butter, but when moving forwards in a diagonal I cannot run. It works fine on a madcatz wired but im trying to avoid it. The problem lies in using a wireless controller. I've tried a few, all have the same problem. Anyone know how to fix this?

My reasons for avoiding the madcatz is probably just the pure shape makes me rage and its dying hardcore.

I use a Wireless Xbox controller on pcsx2 with no issues. Using the lilypad plugin in 0.9.7 version.

Not sure how you can fix your problem though.. Check their site for issues maybe.
