I think Spurgurgle used Modded matt's 555 timer rapidfire and for one
no i did it with a cg pad and hazers gameplay rf
i wired the anolog click to a tactile on the back running on the left trigger out put for gameplay rf i didnt wire up the right trigger out put...
i explain how i did it here

with rf abxy but it works the same on all face buttons for the cg pad (dont quote me on that....) n i think you can get it to work with matts 555 rf. think u need a transistor for that or maybe you dont need the transistor.... i cant remember
but i know using hazers gameplayrf works fine......
