Here is my “Frankenstein” creation. Case taken from a broken Playstation.
Powerd by a 2A power supply switchable over the orginal power-button.
Reset and open (exit) modified with two minipushbuttons to press two keyboard keys simultaneously, cause pad and keyboard won’t work for me like i’ve planned it. The four buttons on the top right are not a optical gimmick, they realy work. X is for the retroarch menu, square is for save state slot -1, circle is for save state slot +1 and the triangle is for pause.
All buttons are like the reset and open (exit) ones with a hacked keyboard on the other end…;-)
Exit the emus, save and load state are working over the pad nr.1.
Pads are USB-SNES Clones on usb-ports, build in the memcardports.
