Hi. The ribbon is easy (if usually one has damaged it cause you were transferring parts to revive one more Dreamcast). In an electronics shop, I just aligned the ribbon contacts when I was buying and found a wider and longer and aligns with the distance of the ribbon's teeth. The one I found is printed: Sony Chemicals AWM 20696 80C VW-1. It needs to be cut to length- width wise (the longer length I believe won't be a problem, it's only a centimeter longer and centimeter wider), maybe tape things down and careful cute with cutter or craft knife with the original cable on it (taped) and a steel ruler over that.
Also I think if one is going to revive a DC by reviving the GD-ROM lens, it's best to just buy a new lens (although that diminishes the all original factor of a collection, coz' if it's just to make things work, play games without regard for the holistic all original experience, its just better to emulate but nothing's perfect), instead of hunting for a defective one with hopes it's got a good GD-ROM which from the start may look 4 to 8 times cheaper but defective DCs (coz' most are unit only, no power cable to test) would sometimes have a bad GD-ROM but power on or a laser that moves (you can see the light) , rotator that spins but somehow doesn't read).
The only difficulty was bearing with sometimes impatient staff while you align the ribbons and do a trial and error, though.
God bless, Rev. 21:4
