As far as I know no Saturns have "wires stretched haphazardly across the board", at least mine don't. Perhaps really early Japanese models, but random bodge wires tend to get fixed pretty quickly for later revisions of PCBs, and like most games consoles the Saturn has quite a few variants through its production run. For example very first revision of the Mega Drive in Japan did have an extra PCB and wires to fix a bug though. But only the first revision, it went away by the second.
