HarumaN is his ID, you can also get him to buy the pads for you and he just adds them to the overall price - if you don't already have the pads then that would probably the cheaper and faster option I reckon. Think he has a pic of the DC hack on his thread on AO.
I see he does Saturn pads as well. Might be worth looking into.
What are the connectivity options to hook a Saturn up to an arcade monitor though?
