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?
A few things I have observed over the years you might want to check. Take a flashlight or something and look at the actual contacts in the port and see if they are bent. Sometimes the old cheap 4 in one carts have poorly made PCBs what arent beveled correctly or are too thick and squish the pins and they no longer make good contact. It looks like an official one in the pic but unless you have had this since new who knows what someone threw in here. see here for some more info on that
Also these backup carts do just sometimes go bad though I don't know if I have ever seen an official one go bad but buying a new one to test may help with that as they aren't that expensive. They also usually have lots of built in features like an action replay and acting as an extended ram cart. Just make sure to try and check that the pcb is made correctly with that link above
