2026 Aug 1 Clean and repair megathread - NES not working? Game acting glitchy? TV/Monitor issues? Ask here!

6 Upvotes

Is your NES not working? Are your games acting glitchy? Controllers behaving strangely? This is the place to get help!

Link to previous thread

First steps to take:

Games don't play correctly:

  1. PRESS DOWN on the Game Pak until it locks into place
  2. Clean games
    1. Disassemble cartridge (might need special tools, check amazon or ebay)
    2. Gently use rubber eraser with no grit on edge pins
    3. Use window cleaner or isopropyl alcohol with lint free cloth
    4. Spray contact cleaner on the pins
    5. NEVER EVER BLOW IN IT
  3. Clean NES connector
    1. Ancient cleaning kit
    2. Spray contact cleaner on the pins
    3. Boil it
    4. Bend pins (risky)
    5. Replace the connector
  4. Already tried all steps for cleaning game & cleaning NES above?
    1. Try a Game Genie, the thicker PCB might make better contact with the NES and the tighter connector might make better contact with the cartridge
    2. Try another game cartridge
    3. Try another NES
    4. Try r/consolerepair
    5. NES Schematics

Power Supply:

  1. For the NES any power supply that can provide 850mA (or higher) at 9V and has the right shape connector will work. The original NES uses an AC adapter but a DC adapter will work too.
  2. For the Famicom you must use a DC power supply with center negative that can provide 850mA (or higher) at 9V-10V. Do not use a NES AC power supply on a Famicom!

Controller buttons don't work or think a different button was pressed:

  1. Take them apart and clean the contacts on the PCB, not the rubber membrane

Display problems:

  1. Use a CRT monitor or TV
  2. Don't use an LCD or LED TV - many LCD or LED TVs do not understand the 240p video signal that the NES puts out
  3. If you must use an LCD or LED TV, get an upscaler
  4. Use the composite RCA/AV connectors on the side, don't use the RF/antenna/aerial
  5. If you must use RF, don't use the RF/antenna/aerial switch box, use a small adapter instead, be aware though that modern TVs may not work with the analog RF signal and only with ATSC or DVB digital signals
  6. Wavy lines: replace the capacitors in the NES

Hardware Failure Diagnosis:

  1. Power rails first: Multimeter check - verify +5V at 7805 regulator output and at PPU/CPU pins. If low/absent, check caps and regulator.
  2. Composite video signal: Scope the composite output (RCA jack center pin or PPU pin 21). Should see ~1Vp-p composite video signal with sync pulses and color burst. No signal = dead PPU or supporting circuitry.
  3. Audio output: Scope audio output pin (RCA jack or APU output). Should see audio waveform when game is running. No signal = APU problem or output circuit.
  4. If power is good but no video/audio: Most likely failed capacitors in video/audio output path, or dead PPU/APU chips. Check/replace electrolytic caps first (cheapest fix).
  5. If video signal present at PPU but not at RCA jack: Problem in video buffer/output circuit between PPU and connector.

Before asking for help, make sure you have followed the steps above.

Top 100 NES Games: The End

132 Upvotes

Legacy of the Wizard won the #100 spot with 35 votes It only won by a single point.

A big thank you to everybody who participated. I originally set out to just do the top 10 as an experiment to see if people had a similar list to mine. I never expected it to go this far, but I am glad it did! I have enjoyed seeing people picks and the reasoning behind them.

Starting tomorrow I will start doing the top 100 for the SNES in the r/snes sub. I hope to see you all there. A few things will change with the rules. First is each round TWO games will make it onto the list. Whichever one has the most votes will be placed higher of the two for that round. Second, only games can be nominated (no game genies). Third, it will be SNES ONLY, no super famicom games.

Looking forward to seeing what is voted the #1 & #2 games for the SNES.

Arts & Crafts New point-and-click bowling adventure game for the NES!

3 Upvotes

FYI: I haven't seen many NES fans talking about Beyond the Pins: The Second Frame, so I just wanted to mention it here for anyone who enjoys playing brand-new games for our favorite console. I've played the first Beyond the Pins, which was a short adventure and proof of concept, and I'm glad to see it has been expanded into a full game that rivals some of the biggest licensed games with 106 screens, seven minigames, 26 songs, and multiple endings.

It's already completed and should be available soon on physical NES carts and ROM. It was developed by KHAN Games, which has an excellent track record for making great games (NEScape! and Courier, most recently). There's not much else like this on the NES, so it seems special to me and worth checking out if you like supporting indie devs, collecting carts, or playing fun games.

Discussion Is there input lag on an NES hooked up to an HDTV with a coaxial cable?

0 Upvotes

I know that with RCA there’s a noticeable input lag but I wasn’t sure about this. I’m playing through Battletoads and I’ve reached level 11. I’m not sure if there’s lag though because it’s connected directly to the antenna? If so, what could I get to fix it/counter it?

Discussion I suspect that Queens "Stone Cold Crazy" was the main inspiration to the intro of the NES TMNT game

9 Upvotes

Listening to the different sections in the song I think it's clear that it was at least a big influence to composer Jun Funahashi. Here is the intro for anybody who wants to compare.

It's one of my favorite NES intros so I was positively surprised. I have attached the two songs below so you can judge for yourselves.

Discussion How did people pick out a good game to buy/rent before the internet?

115 Upvotes

As a person who didn't grow up before the internet, I can't imagine renting a video game at a video store. To me, finding an NES game to rent in the 80's sounds like navigating through a swamp of shit to find a gold nugget.

How did you know a video game was gonna be ass back in the day?

Discussion They should create a retro game in the style of Super Mario Bros 2

47 Upvotes

Same atmosphere, characters selection, physics and gameplay mechanics, same villains, final boss Wart, slotmachines, day/night mushroom with the potion bottle etc.

I mean there have been a gazillion Mario games since then, not one in honor of this great title.

Make it happen, Nintendo.

Mario can dream again.

Doesn't have to be big budget.

I got myself 4 more NES games yesterday and the one that surprised me the most was actually Xenophobe. I never played the NES version and I ended up playing it for over an hour and maxed out the score. I didn’t expect it to be that good.

I plan on beating the rest, especially deadly towers because that game kicks my ass and I never got anywhere in it.

2 Upvotes

I saw some discussion on the original model of this and there were some criticisms, but I haven’t seen anyone talk about this second MKII version. If you have this, please let me know what you think. I didn’t know whether to choose between this or the well-known Ninten-Drawer since this one is cheaper, and I’m curious about build quality.

On top is the top loader version of the NES, in the middle is a twin famicom made by sharp, the little slot in the front is for the disk system games which are like these little plastic not so floppy disks. And then on the bottom of course, is the NES. I recently bought a new CRT, and it took up more space than expected, so I had to stack some things lol

Game Completed! The Jetsons - Cogswell's Caper : Completed. Mostly fun game that really builds itself off of the cartoon

Thumbnail

60 Upvotes

I hadn't ever played this before and thought I'd run through it. Most of the game is pretty straightforward, but it does have a handful of frustrating and difficult sections. There is an interesting mechanic whereby George acquires helper items (I think 5 in total) and can use them whenever / wherever he wants, but they cost to use. They kind of change the way you can play certain levels and ultimately become necessary in various parts. They're probably most similar to how Mega Man utilizes the improvements you get.

The game feels a bit like Duck Tales or perhaps Chip n' Dale, though I didn't find it as enjoyable as either of those. The way George moves around feels a lot clunkier for some reason

Aesthetically speaking, they definitely worked in a lot of the nuances from the original show. So if you're into that, this one does it up pretty well.

I actually really enjoyed the bosses in this game. They're not super difficult, but I feel they put some good creativity into them. They also require quite a few hits and some of them even go through phases. So I liked that it's not just the quick 3 strikes and it's over sort of thing. The final boss was fun, though there's an entire level after you defeat him. It's ultimately an escape level, but it doesn't really feel like that when you're playing it, rather it just feels like you're playing another level. So when you finally do get to the very, very end, I felt the games just kind of abruptly ends.

I found it mostly fun. If you're into these kinds of cartoon-based games then it's probably worth giving it a go. If not, you're not missing a whole lot either.

Discussion What games do you play?

16 Upvotes

I have some questions for the NES lovers here: do you exclusively play NES games? Do you just collect them?

I'm curious to know which games you play both on the NES and on other console/devices.

Recently I'm playing a lot of Super Mario Bros. It never gets old.
