Dreamcast TO Saturn adapter?

Got a agetec stick 4 dc an wonderin if there are any pinouts for dc connectors. I know there are saturn to dc adapters but i want the other way around. Plan on gettin a controller extension cable an splicin that up. Anyone know where there are some pinouts/directions or anyone done it b4?
It's not as simple as rewiring the connector, but if you *really* want to do it it can probably be done with a microcontroller. The relevant info on the Maple Bus is here (wire protocol) and here (logical protocol). The info on the controller data encoding is here. If you can handle that, the Saturn side of the interface should be a breeze. I'm not sure where to find the SMPC manual online, but I'll get the relevant info up here sometime tomorrow if I remember.
