I don't understand how to find the "Pop'n Music Controller" setup. I downloaded the latest version of PCSX2 (the one ssakash posted), looked around Controller (LilyPad 0.11.0) setting but I did not find any configuration for Pop'n Music. Where can I find it and how do I setup?
I built a Pop'n Music controller with Arduino board and I was ready to play, but following the layout of ecxol or PS2 controller messed it up.
