DO NOT DO THIS ON A CARPET!!! I'm not sure what he was thinking in this video but trust me, not using a static safe earthed mat and wrist band is a very quick way to kill any peice of electronics.

Replace the pin connector Disabled the lock out And cleaned out 3 games. Simon Quest ll, friday the 13th and the legend of Zelda all cleaned out alcohol very well and only simon worked for an hour but had to wiggling back and forth for 15 mins. Any idea to fix to the point where games works perfectly?

I suggest your press down the cartridge if it's grey while testing it.

i have an Asian NES. Will i be able to play NTSC games on it if i remove the lockout chip?
Report spam or abuse
The famicom (Japanese Nintendo nes) has a 60 pin connector while the American NTSC nes has 72 pin connector. The only way you could play famicom games is with a famicom to nes cartridge converter.
Report spam or abuse
Sorry, I actually meant to order to play nes games on the famicom system you have to have a nes NTSC converter.

I did this and when I tested the game with the sled, I get a grey screen. If I remove the sled and just push the game down, it works. I cannot get it to work with the sled. Any ideas as to what the problem is? I also did the 72 pin repair by cleaning them and pulling them up.

I just tried this method and I can honestly say it works great! I had so much trouble getting specific games to load, especially Tecmo Bowl which would take around at least 20-30 tries of loading and blowing on. Now I can just blow on it once, pop it in and I'm ready to play! Thank you!

want to fix all this without a new 72 pin or messing with it?? get a game genie and keep it in your system makes every game work or buy a nes flash cart and emulate the roms so you dont take the cart in and out and wreck the pins

You might have to do one of the following if you haven't already: Clean the Games properly with alcohol and sandpaper Bend the pins in the NES and or clean them Clean the motherboard connector to the game connector thing (bad explanation, sorry) Replace connector

I always appreciate the people who do these "How to" videos. I disabled my lockout chip without a problem. I had 21 screws though not 12. Reason being is that mine still had the signal shield over the sled. Thanks for the help! I have to say one thing though. Never!....Never!....NeverNeverNeverNev-eeeer! do any type of electronics repair on a rug. The amount of static electricity in a rug is ridiculous and it will fry your shit. When I want to completely burn my old hard drives out so they're completely unreadable or operable  I put them board side down on a rug and vacuum around them. Fries them every time.

I just clipped mine and it works so much better.  I used a utility knife with extreme care.  Games load about 90% of the time now.  Thanks for the video.

I wish I had known about this back in the late 80's! Of course, you weren't gonna read about it in Nintendo Power. Other than this, is there anything else that can be a problem? Won't the nintendo eventually wear out anyway, because putting the cartridge in and pressing it down over time bends the pins, to the point where it will no longer work- even with the lockout chip disabled.

You don't even need a real nes now, just use an emulator

I tried all the other fixes: clean the 72 pin, re-bend the 72 pins for more solid contact, etc.  nothing fixed it. I did this small mod and voila!!!! I'm back whipping monsters in Castlevania and nitro boosting in Mickey Thompson Off-Road in all their 8 bit glory!!! Thanks Slap!

Fixed the blinking red light, but not the NES

The old breath trick always work. You grab the cartridge, you take your free hand and cover the opening of the cartridge leaving just a small hole expose.  You take your mouth and cover that hole and blow 3 puffs of air into the cartridge.  Insert that cartridge into the NES and power it on, and the game should load right up. This method also works on 32X and Jaguar cartridges that have trouble loading.

+Gord Peach I wasn't being insulting, though I knew how it would come off that way. And what you said sounded as if you were making it up on the spot. I read the links, it's speculation, and in all I've read about the NES and its cartridge problems I've never heard of such a theory.

I'm getting forgotten memories of the NES era and trying to get these cartridges to work. Right now it doesn't seem like much because not as many people play NES games compared to back then, and the ones who still play usually use emulators. But if only I could go back in time and do this, it would be gold.

yeah it plays all nes games(pal, ntsc, australian....) exept famicom games

Take apart the game cartridges and clean with brasso metal polish. And while u have the board out and pin connector off, clean the pin contacts on the board with brasso as well. And u might as well replace the pin connector. They are less than $10 on ebay. I just did all of this to my console and all my games last night. It works like new now.

Refurbed connectors are normally really tight. Any advice on making them less tight? Maybe leave a game in there for awhile?

Works great. I did this while replacing the 72 pin connector as well and its a quick and easy fix. Thanks for the tutorial!

Will this help resolve the purple screen? I cleaned the 72 pin and tried it out, worked great for one game but now won't do anything but turnurple for every game I try!

Note that this method WILL make your NES region-free.
Report spam or abuse
or you could just get a new connector and clean your games. they are pretty cheap, and if you can't order one online, for whatever reason, a lot of old game stores that sell NESes may also sell the connectors since most of them carry them anyway. although i cant guarantee that but all of the vintage stocks and game eXchanges in my area sell them for about 15 bucks.

Or you could do this easy free trick to fix an a problem competent in the NES that will permanently fix your issue. Unless you get mad when you try to put in pirated / other region / unlicensed games into your system and they work without fail. :P
Report spam or abuse
I've heard the new pin connectors are hard on the games. I like the idea of just opening up the console and cleaning them out while you realign the pins. If I can learn how to kill the lockout chip the right way (not this way), I will do that too.

Its better to ground the forth pin because after a while, the circuits may fail.

And to think I back in '88-'91 I used to lick the pins in my cartridges which made them work and never tasted good...

+vadont That's because that's ONE way to get a blinking red light. It does not mean that's the only situation where it occurs, or even what it means. It;s rather like saying "my car didn't start, so I replaced the alternator, therefore ALL issues where the car doesn't start is an alternator problem".

Try cleaning your games with a light alchohol q-tip. Also do not shove your games in all the way, slide them in gently and push down so it slips over the edge before you press down. Do not force it, be gentle.

I love that at 3:46 the song "What is Love" (Baby Don't Hurt Me) kicks in as he opens up the NES. Its cathartic. The blinking NES was at one point in my life my biggest problem ;) Now it is gone!

@mrmeowmix2300 Actually I cleaned it up but had to lift all the pins on the 72 pin connector, its really stiff to get carts in and out now and sometimes games still refuse to load, sometimes they start and continuously reset for example. If you get the cart in right it works though, but in the end I ordered a new connector from the US (I live in England) for about $10 inc shipping which is a good deal imo as Euro sellers take the piss on the pricing.

Don't listen to this guy I've tried it myself and my system stop working as well. All you need to do is replace the 72 pin connector and make sure you clean the part where the connector was connected to. And if all fails, the motherboard is completely dead. So try getting a bacq up system just in case or better yet get 1 and pay for the 2 yr.warranty like I did. My dad love this system, so I just gave it 2 him. So now I'm bacq on my PS3 & X-box :( aka Blaze

im not a expert at this so im gonna ask this question. What does disconnecting the 4th pin on the lock out chip do exactly?
Report spam or abuse
Since your console only dose this part of the time, the lock-out chip is not your problem. Your problem sounds more like the 72 pin connector. I had the same problem with mine.
Report spam or abuse
As fa as I can tell the lock out chip is there to prevent you from playing games from other regions, like europe, japan etc. and of course clone games. There's an added bonus in disabling the lock out chip because then you're able to play games from different regions.

@Englepest there are many ways to try to get the game to recognise is it just one game?
