I've been using, with great success, my PS2 controller on Nintendont. It took some trial and error to make the button configuration ideal, but I have and it's great.
And then I tried getting into Super Mario Sunshine. See, long story short, it is essential to the game that you differentiate between holding the R trigger all the way down and holding it part of the way.
However, the R2 button on the PS2 controller only has one input (it isn't analog; it's either pressed all the way down or not).
Right now, the R1 button my controller is mapped to Z. I can remap the Z button to the Select button. But I need to make R1 a half-press of the R trigger, and R2 a full press.
How can I, in the controller configuration, remap a partial press of the R trigger to a separate button?
