I just opened the console and cleaned the port and memory cartridges and it still won’t read.
I reckon the hardware is getting too old.
However, I prefer the original hardware without any fancy upgrades like a new operating system.
Pieces are also chipping off inside and I just had my Dad fix the power cable port by gluing a piece back on there to fix the power cable usage.
Thoughts?
If I can get at the connector I prefer to de-tarnish it with Flitz, then after a bath in contact cleaner I'll goop it up with dielectric grease, which ensures I will not have to do it again any time soon.
You can realign the leaf contacts carefully with a dental pick or, if that doesn't come to hand, a pin with a short 90 degree bend in it. You can also truly realign the pins in specific connectors if the fancy strikes you; my front loader NES will now happily (and easily!) play cartridges without having to push them down.
