one more thing, in the Mame folder there is a Mame.ini file in there is the Joystick sensitivity and deadzone
I changed my sensitivity to 100 and the deadzone to 0
be careful with this as it applies to all games, but the U360 maps have there own deadzone so it seems to work fine for me and that way you get 100% of the analog range from the stick
I'm pretty sure the digital sensitivity doesn't do anything on an analog stick
also hogie1418 you may want to modify the Subject line to add something about analog settings, might hep a few more people out
