The DSP adapter is a pass through connector that goes in the cart slot of the Doctor SF7. The gamestation doesn't have a cart slot, so it's impossible. On Rob Webb's site I believe, it says there isn't even a cart slot internally. So the sf7 board is different.
And no, I don't have one. Like I said in post #3, I wanted one real bad but could never find one. But I definitely did my research on it back in the day.
EDIT: By the way, this only makes about 10 games that are incompatible with the gamestation.
