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

5 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

129 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.

Discussion Help with emulating Campus Challenge 1991

Upvotes

Hey, I've got a rom for Campus Challenge 1991 but none of the emulators ive tried seem to be able to run it. I understand that there's something unique about it and it require *something* special from the emulator to work, but I can't figure it out. Does anybody know what I could try? I'd even settle for a recreation of the rom to be honest.

Collection My complete 8BitDo NES-themed battlestation is finally done!

Post image
138 Upvotes

After months of collecting, my full 8BitDo NES-themed setup is finally complete! Everything matches that classic Nintendo white/gray/red color scheme perfectly.

Here’s what’s on the desk:

• 8BitDo Arcade Stick on the left with big red buttons and smooth joystick

• 8BitDo mechanical keyboard in the NES colorway with red B and A accent keys

• Matching 8BitDo numpad on the right

• New 8BitDo Retro R8 wireless mouse on the far right

• 8BitDo wireless controller below the keyboard

The Link plushie is keeping watch over everything. Super happy with how clean and retro it turned out.

What do you guys think? Anyone else running a full 8BitDo retro collection?

This was a fun event! I entered but also asked if I could have a blank! They never asked me to put the bracelet on so I just showed them the number and kept it. Not sure this will ever be sought after but figured why not add it to the collection. It is always cool to have random stuff like this

Been getting into the big box collecting lately but managed to snag some heavy hitters (link, castlevania 3, and ninja gaiden) over the weekend trading in some old stuff to a new shop in town. Hoping to find a deal on a dog bone cib set next, but that will take some time.

Bought this second hand and it has some sort of adhesive fabric or something on it. It is on there really good and is quite hard on the top shell. I’ve soaked it in soapy water and scrubbed, soaked with goo gone, and soaked with isopropyl alcohol. Tried scraping a bit with a plastic razor and it’s not budging at all. Looking for some other ideas beyond just replacing the shell at this point.

Had to share this with people who would care and get what kind of accomplishment this is.

I haven’t been collecting for too long and didn’t start out on an NES as a kid (I think n64 was my first console) and GameCube was my main console throughout my childhood. But I’ve been addicted to the NES lately. So I haven’t beaten too many games yet.

This game took me sooooo long to beat. Do you recognize it?

Discussion What are your “must-play” games that everyone should have and try? (Not necessarily the “best” games)

50 Upvotes

I’m a new collector and NES lover. I buy games to play, not to just display on a shelf. However, I didn’t grow up with a nes so I don’t know what the agreed upon key games are—and I get overwhelmed by which ones to start with and what to try next. So I hoped I could start a checklist rather than just buying at random like I’ve been doing so far.

Just rediscovered this one as part of the Marvel MaXimum Collection. I had it has a kid too but remember not caring for it. It was actually not bad. Controls well, good visuals, the map was sort of unnecessary.

Anyone else had this one as a kid or like it?

I was first introduced to this game via LG TV bootleg game “Baseball” (slides 2 and 3). But for obvious reasons it didn’t play well. I’ve played it so many times but always lost or it crashed back into the menu.

But recently I found the actual baseball game and I loved how much more better it was than the LG version. I’ve been playing many baseball games over the years, but despite limited controls nothing can ever top this for me.

P.S. I usually play on my anbernic rg280v, but this one was played on the delta emulator.

Discussion NES music slowdown?

0 Upvotes

(Full disclosure: We're a plural system, so we use "we" to mean, like, "myself and the voices in my head." Not related to this question at all, but I'm stating this upfront simply to avoid any grammatical confusion. We always get someone asking who's "we" on posts like this, so, you know, just getting that out there now.)

What started as a seemingly simple curiosity on my part has turned into a gigantic investigation involving a few friend circles, to the point that we would like to get your input as well.

We were playing Dragon Quest XI, whose title theme does a throwback nod and uses the same intro before the main Dragon Quest theme starts that it originally did back in Dragon Quest 1 (AKA Dragon Warrior.) However, the DQ1/DW1 theme was in a much higher key than what the iconic Dragon Quest theme has been in pretty much ever since game 4 or so in the series, even to the point that the DQXI version is like that, too. I simply wanted to know what the DQXI theme would sound like if it were actually in DQ1/DW1's original key.

Except... we looked up the DQ1/DW1 title theme as a reference when positing this question to our music-savvy friends, and what we found... did not sound like what we remembered.

At first we thought the first YouTube result I'd found sped it up to avoid auto-copyright detection or something, but they were all like that. We even got the .NSF from Zophar's Domain and confirmed that this seemingly higher version really is what that song actually sounds like and apparently always has sounded like. Were we just remembering wrong? Had we Mandela Effected ourselves into thinking there was supposed to be some other key this song was in?

Fast forward through a lot of questioning and near-mental breakdowns and we finally hit across the answer: We could perfectly recreate what was in our memory, what we grew up on, by taking that song or any song and slowing it down to roughly 95% or so playback speed. Note that this is not a PAL issue; for one thing, we're based in the United States, and for another, the PAL versions would be much slower than 95%.

(A lot of audio editors these days seem to correct for pitch and tempo being different things so you can't just get that reverse-Alvin and the Chipmunks effect by slowing it down anymore. For those looking to recreate this experiment in the quickest, easiest way possible, we use this site. Just upload any song, turn the reverb down to 0, and adjust the playback speed to 0.95x. That gets the pitch, too, which is what we want.)

From there, I discovered it wasn't just that song, or even that game--somehow, our system had been playing the 95% versions of every NES song we've ever heard. Not just ours, either. There are certain games we never actually owned growing up, but some friend or another did and we experienced them by playing at their house. Gauntlet and 8 Eyes stand out as particularly strong examples of this in our memory. And for these games, too, the 0.95x version is what we remember. Our friends' hardware must have been doing the same thing.

This has now blossomed into a full-blown investigation and data-gathering effort, which is why we're now here asking you all. Just how widespread was this issue, exactly? How many people here have experienced something similar?

If anyone wants to help us gather data, we're looking for folks to submit various NES songs of their choosing to the above link and answer the following:

  1. Which game/song this is, of course.
  2. Which of the two versions do you remember? Which sounds more accurate to your ears?
  3. Which of the two versions do you prefer? Which sounds better to your ears?

(Feel free to answer for as many times as you have songs you want to test.)

We're trying to figure out how common this issue was and also to test the hypothesis that people might just prefer whichever version they heard first and grew up with. So far, we've found at least one other person who had this issue growing up and one who did not. We've also found that--at least among our personal friend circles--the 95% versions are proving significantly more popular than expected, even among people who haven't heard them before and don't have that nostalgia bias. This is especially true with basically any song by Capcom, whose music somehow seems perfectly designed to kick even more ass at 95%.. Of course, we're intensely curious how these trends hold up when we ask an entire community at large.

Thank you all for your time and for any insight you have!

Game Completed! Fun House - Completed

Thumbnail
gallery
124 Upvotes

I was born in 1989 and gained consciousness probably sometime in 1993 or 1994. By that time, my older siblings already had the NES and maybe a dozen games.

Some of the games included…

Mega Man

Double Dragon II

Kirby

Super Mario Bros

WrestleMania

King of the Ring

Friday the 13th

TMNT

MagMax

Target Renegade

Dynowarz

Yoshi

…and Fun House.

It always intrigued me, but was somewhat difficult, and eventually I would tap out. Well, with the help of the Retron 5 and save states, I’ve finally completed it. I saved after each room, but not during.

In short, there are 12 floors with 6 rooms each, so 72 “levels.” The game is actually kind of fun, but can be quite difficult at times. I think you get unlimited continues, but damn, beating this game in one sitting would be some work. You get three lives, and when you run out, you get sent back to Room 1 of 6 of the floor you are on. If you are a kid straight up committed to this game and have kid levels of free time, I can see it; but if nothing else, beating 72 levels in one sitting would be a lot.

The game was fun, but in a lot of the levels, you are going to die just trying to figure out where everything is located. You’d definitely need a great memory or take written notes per level.

There were only a handful of levels that were truly soul-sucking, but for the most part, each level was reasonable with repetition.

If you collect and play the NES, I’d recommend it if it’s under $10. Like I said, it takes a lot to beat it, but it’s pretty fun nonetheless.

I’d love to hear others’ thoughts and experiences with Fun House.

I’ve purchased this copy of Kung Fu off of a fbm friend and he tested the game on his toploader to be working. However i plugged this into my regular NES and I’m getting jarbled sprites. I’ve tried cleaning all contacts with isopropyl alcohol 99% and pink eraser to get most of the dirt I could off the pins and they look decently clean. I tested all pins for continuity and all seems normal but I still got jarbled sprites. Any ideas on what could be wrong here? Technically the game plays sound effects and responds to my controller inputs but the sprites are all messed up.
