By popular request (or not), I'm posting this schematics of the console, as CC by-sa license.
There is already quite a list of errata, so expect a rev2 of the board corresponding better to what I have now, after having pcb traces cut, Boot0/1 resistors added (still learning !), tiny wires soldered directly on lqfp pins ... But, that is the basis I have been working on. I will make another, better revision for sure (yeah, right, promises).
