Re: pin-out for DC add-on port
It's called the "G2" BUS, apparently. This was the most detailed description I've found, although there were a few other obscure resources around the net:

Soooo what do you plan to do with such privileged information?

Re: pin-out for DC add-on port
Thank you for the page!
Well, mainly out of hardware interest but i am also curious to see if there could be any solution to either piggyback the dreampi in some smart way or replace the complete unit.
This will probably never be done by me but something fun to play with!.

Re: pin-out for DC add-on port
Yeah, actually someone just posted something like that the other day in one of the Dreamcast Facebook pages. They had a really cool hardware mod with a standalone Raspberry Pi connected to that port.
I haven't looked at what the power output is on that port, but the Dreamcast has two gigantic, very open pins immediately after you take the top off for 5v and 3.3v. It's absolutely trivial to hang things off of those to power them. I've used the 5v to drive a Raspberry Pi myself before.
