This is quite a long video about replacing the rear power connector on this Super Nintendo. On this shell design, the power socket is built into the rear plastic panel rather than being a simple board-mounted connector, which makes replacement more awkward than it first appears. Maybe Nintendo expected the entire rear panel to be replaced as a service part; I don’t have evidence for that, but it’s the only explanation I could come up with at the time. Anyway, watch on and also enjoy some Biker Mice from Mars!
