NEC — PC Engine CD-ROM2
This NEC PC Engine CD-ROM² threw everything at me: 3D printed gears, a dead laser, a Discman sacrifice and a spindle height mystery, before a full recap finally brought it home. Worth every frustrating hour of it.
A Totoro with missing gear teeth and no matching replacement in any kit I could source. Two gears cut, filed and glued into one that works. Totoro snores happily again.
