NES Cart Fix v1.2
 
Fix for flawed frontloader cartridge connector.
This is replaced with a standard 72 pin connection like the toploader.
This eliminates the terrible bendy pins design.
Never have cart connetion issues again.
 
Customer Review:
 
The cart fix is super important as it makes the Nintendo consistently reliable. I would definitely promote it more. 
 
I've never had this level of consistency since the Nintendo was brand new and I've tried refurbishing old connectors and using new connectors. The only thing is that works 100% is your cart fix and the Blinking Light Win. 
 
I'd say your cart fix is better than the blinking light win as it's easier to get the carts out and feels more robust. You also don't have to cycle though the region codes, providing you've done the region free mod. 
 
Installation Steps:
 
1. Cut off bottom strip of cart tray and add bolt.
 
2. Solder on 1st pin strip to frontplate
 
3. Solder on front plate to edge connector on all 4 corners.
(leave 4mm gap from green solder mask)
(make sure plate is perpendicular and straight)
 
4. Loosely fit in 72 pin connector, position tray with cart and insert into connector
Solder a couple of pins to hold into place.
(this makes sure the connector is soldered at the correct angle) (pic 6)
 
5. Solder connnector in place with tray and cart removed.
 
6. Solder on black plate.
 
Screw on tray and you should be good to go with no more connector troubles!
