Game Link Cable Repair

Fear not. Old GB link cables, specially third party, tend to eventually suffer from contact failure. Connectors are usually OK, but the wires not, which will give much headache if the link is used to transfer data (hello corrupted saved banks, hello wasted last night).

The fix is easy though, cut the defective parts and solder back the… possibly much shorter… new cable.
