72-pin replacement photos

#1 Posted by Alphazero (1536 posts) -

I got a cheapo NES from eBay that wasn't loading games, so I tried replacing the 72-pin connector. It worked great. The craziest part was loading up Legend of Zelda II and seeing my save games still there from 20+ years ago. 
 
Also, I can confirm that Mega Man 2 is waaaaaaay easier than Mega Man 9. Even on difficult mode.

Haha, took me a small while to process that sentence. Forgot for a second that games used to write saves to the medium itself and not to an external drive. Man that was ages ago. Is it still functioning?

Where did you get the connector? How easy was the replacement? Maybe post a blog showing the process? I've still got my original NES from 1992 but it's very finicky. Once I can get it to load and play games I have to be very careful not to touch it again.

I believe Ebay still has the 72-pin connectors if not just google search.
 as far as replacement its as easy as sliding it off the board.

Hey Joker,
 
I got the connector from eBay for about $2 plus $4 shipping, you can probably find it cheaper. The replacement process was remarkably easy. If you're comfortable putting in and taking out a PC video cards you can handle it. The best part is the NES uses normal phillips head screws, so you don't need anything too funky. 
 
I used the directions on this site. Getting the cartridge loader back on was the only tricky bit. Overall an easy fix.

It totally blew me away. Two of my saves and one from my sister were sitting there, just fine. Zelda II had a battery inside the cart, which I assumed had long since died. It must have some sort of flash-like memory in there, maybe? I have no idea how the data is still there.
 
I haven't tried saving a new game. Perhaps that's the part that requires a battery.
 
Anyone know how the internal storage media worked for Zelda II?
