This may be somewhat basic, but so far I have only done simple soldering without knowing about about eletronics.
When I built my stick, I drilled 10 button holes (start, select, 8 action buttons). I don’t want to cut another hole for the PS button, so I thought about bringing back the “SELECT+UP = PS” method you guys may know from PSX adapters when used on the PS3. Basically: to do a PS-Home-buttonpress, press SELECT and hold UP on your pad/stick simultanously.
Is it possible to accomplish that functionality with this wiring?
