So much Game Boy R&D happening!  I’ve just built a sync box out of a DMG-07 multiplayer adaptor.  This means I can sync more than two Game Boys at a time, allowing me to start/stop/play everything at the same tempo by setting a master Game Boy and several slave Game Boys.  This is done by removing most of the parts on the DMG-07, throwing them the fuck out, and adding a wire and smearing solder over everything.  And then it works, probably by magic.
