Defor, since the PS2 Taiko controller only has two wires for each of the four sensors (GND and Input), it's not possible to wire those directly to an I/O board (via Mitsurugi-W's JVS Helper PCB) is it?
I'm guessing you need something like an Arduino Mini to convert the Playstation 2's drum controller hits from digital to analog...?
well, if you think about it, you can bypass the ps2 control board entirely- you've got analog sensors sitting right there.
this is the same method you'd use with the arcade drums.. I'll see if I can draw up some simple schematics before the end of the weekend- sorry, a bit dead at the moment- was up until 5AM version testing (199) 246/256 game dumps
