How to disable an nes lockout chip pin 4 fast and easy- Video tutorial

[icemanxp300]

Ok so I have been meaning to make a video to show people how easy it is to disable a nes lockout chip. You only need two screwdrivers a Phillips for the screws and a small flathead for the pin.

This is by far the easiest way. You first pry on one side of pin then pry the other side a bit and if it is tight area on one side over the other finish prying on the side that has more room. The video is under 8 minutes but I didn't realize this system had a security sticker on it and it has been so long since I disabled a chip I stopped to verify I had the right pin lol. I could easily do in 6 minutes.

The only other thing you need to know is when putting it back together the tray tab must go under the board for the nes to function properly. If you don't I think it messes up how the cartridge get pushed down, sometimes it works in up position.. just save the hassle and put it back together the right way lol. I posted a picture of that part.

step 1. Remove the 6 case screws
step 2. Remove the (I think) 6 sliver shield screws
step 3. Remove the 6 black tray screws
step 4. Remove the 2 power box/rf screws
step 5. Remove black tray from board.
step 6. Separate board from bottom silver shield, can be a bit tricky if you don't want to unplug any wires
step 7. Locate pin 4 then pry it out.
step 8. Put back together. The tray tab must go under the board- this is tricky, requires prying board up and tray down and in at same time.

WARNING TO OTHERS: DO NOT PREFORM ELECTRONICS WORK ON A CARPET. STATIC COULD FRY YOUR SHIT.

Good stuff. I have two original Toasters and they both have the continuous blinking LED so I was intending to do this next time I have the time. Just gonna clean and maybe boil the pin connector but figured since I ma going to be in there anyways might as well disable the chip as well.

Yeah. Shawn is right this shouldn't have been done on the carpet but I wasn't too worried over it. I worry a lot more on other things but not this and I don't know why lol. If this was a video card or something I would be concerned out the yin yang. Maybe it's because I have so many nes laying around I don't care much about them.

 

If this was upstairs instead of on top of a concrete slab (my basement) I probably wouldn't have done it, don't know if that matters but there isn't much static down here. Either way when you do it do it safer lol. Principles are the same, it is easy. 5 minutes would be doable.

I am electronically clueless, can't solder, etc; even I have done this. Only difficulty I ran into was losing one of the screws. Pay attention to the directions, go slow, it's easy.
