Here is a detailed procedure in english for "hacking" the original control panel from the Project Diva arcade cabinet, for using it with the PS4 version of Project Diva. I followed everything from the author of the hack : http://ryun.halfmoon.jp/touchslider/ All credits goes to Ryuhalfmoon. He also helped me during the process, gaving me all necessary explanations. The procedure includes 3 major parts : - Sourcing the control panel - Hacking a PS4 dualshock - Build and program a FPGA circuit board, to enable communication between the dualshock and the touchslider. So here we go. I will separate the process in different posts, because a one shot post would be too heavy with more than 20 pictures.
