Ppsspp with xpadder force device?

[Ske1etonkeys]

I did. When I looked up problems with button/controller mapping I got a list of tutorials of how to use it with xpadder to fix the problem. I didn't realize that I guess there's full
usb controller support now? The problem is when I try to map the controller I have to press the buttons in a split second or it just maps the enter key and some buttons will not map at all. I don't know why.
