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

7 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.

Collection Whatโ€™s your favorite/most hated game in the TMNT Cowabunga Collection?

16 Upvotes

My personal favorite is The Manhattan Project, mostly due to having the original NES cartridge. Never was able to beat it without cheat codes, though. ๐Ÿ˜“

Most hated would be Fall of the Foot Clan. Itโ€™s like a half-cocked fan game. At least they actually put in effort for Back From The Sewers.

(Guilty pleasure is the original NES game. I actually made it to Stage 5 back in the dayโ€ฆ)

Game Completed! I finally beat The Empire Strikes Back on original hardware

56 Upvotes

First off: This game is not good. It's stiff, poorly designed, and its difficulty is through the roof. It also has really grating sound design, which is puzzling since it also has moments of amazing sound with digitized voices from the movie.

I had the game growing up and it might as well been impossible to beat. Even through adulthood, any attempt at it ended in complete frustration. It's the kind of game where you need to learn all kinds of little obtuse workarounds to advance through, and there are a LOT of them. Get stuck on a new problem area that drains out your continues? Tough, better hope you figure it out on your next slog of playthrough. Want to beat this boss? Find the one spot where it can't reach you, and just fire your pea shooter of a blaster at it until your thumb falls off. There's little skill here other than sheer memorization and choreographing of every move through the game, and knowing how and where to nerf your way though. Slip up once and it can lead to an insta-death. I ended up having to study longplays for the second half of the game to get through it, which kind of felt like cheating, but I would have NEVER beat this otherwise. I have no idea how any child could ever beat this, or honestly any adult without similar help. There's a reason that most longplays on youtube use a turbo controller for it (which I didn't use, for the record).

Also, I actually love the first Star Wars game for the NES, which I mastered many years ago. That game is also hard, but in a way that feels like it rewards skill, not memorization, and its side scrolling mechanics are way ahead of Empire. The games have similarities, but they also have some pretty core differences that always puzzled me. Like you could tell a different team handled Empire. That's for another post another time though.

Anyway, this was one of my main NES 'Mount Everests' and I'm thrilled to finally check it off. There's only a few more hard games from my childhood that I still need to beat now. I'll end with some positive notes: It has pretty good graphics and some fun cutscenes. Some of the digital voices sound like they're from the 16-bit era. It also introduced some neat side-scrolling vehicle levels that Star Wars didn't have. I suppose I also begrudgingly developed some kind of backwards fondness for it now that I mastered it, like one tends to do when they finally beat a hard game. It's a shame that a Return of the Jedi game was never made for the NES. It's one of my biggest video game "what-ifs".

Does anyone else have any experiences with this game that they'd like to share?

Discussion Need help finding two specific games

9 Upvotes

EDIT: Case solved. The games are Adventure Island and Circus Charlie.

Years ago, when I was around maybe 7, I remember playing a few games on nes at my grandparents' house. First was Mario, but the other two are less know, so I've never encountered their names on the internet. Thus, I don't really remember them enough to find by googling (tried). I want to find them and see what they actually look like beyond my memories.

First was a tropical themed platformer with pastel colors. I remember yellow (beach), blue (first level had a light blue color, but also water), green, and pink being more prevelant than others. The protaganist is a boy with brownish hair.

Second had levels, but wasn't a platformer like the other two (tho it did make you control a character?). Circus theme. Blue, red and maybe purple were the main colours. What you had to do (I think) was to pass challenges akin to circus tricks like going on a rope on a mono bycicle.

I barely remember them. These are the only details that I clearly remember. Any help would be appreciated

When I was a kid I remember being trashed by the AI with this game.
Couldn't score a goal and the AI always scored.

Then when I went back to play as an adult I discovered the gimmick of scoring against the AI in just two play troughs, just shoot in the centre of the goal and you score every time.

I found out as well the short guys (mid speed mid strength) where op against any opponent. (As a kid I thought mix and match were the way to go.

Collection I just got a copy of Montezuma's Revenge for the NES

110 Upvotes

I know I'm a little late in getting this game but in all fairness, I just found out that this game exists a few weeks ago. I liked the story behind the creation of the NES port of the original Atari computer game and it look interesting to me, also I really like to add physical copys of games to my collection. I tried it out and it gives me a Load Runner vibe, which makes sense because that is also an early computer game port. The color palette and sprites used in the game definitely give an Atari2600 vibe and I'm down for, I saw online during my research for this game that one of the criticisms was the graphics but I disagree, I think if this game was ported to the Famicom in 1984 it most likely would have looked similar to this anyways. I'm looking forward to playing more of this game and trying to beat it. One of the odd things is (that doesn't have anything to do with the game itself) that I was having trouble dumping the ROM with my sanni OSCR, so I tried my INL Retro but also had no luck with that. I had the same issue with my Limited Run Games release of Gimmick too, if anyone knows why please let me know because I spent about a hour and a half fiddling with it and nothing seemed work. One last note that I would like to add is that I really do dig the colored cartridges that a lot of new NES games are coming in, this orange cartridge adds a bit of variety to my collections color along with several of my other newer released games.

Game Completed! California Raisins - Completed: The QWOP of NES titles

Post image
102 Upvotes

Let's be clear: this game is hands down awful.

But after doing a bunch of reading, I came to find that the ROM file floating around is essentially a demo/prototype of the last version the developers had approved before Capcom cancelled it.

Unfortunately the game just doesn't work very well. It's largely based on climbing vertical objects (like vines or pipes) only a good chunk of the mechanics around that very critical component don't work. It's often impossible to land what should be trivial jumps or to jump off of a climbed object. Most of the enemies are overly simple, but then others are basically just impossible to avoid. It's very imbalanced.

Ignoring the whole California Raisins branding thing, the unfortunate part is that I think it could have been an okay game. You can see how the levels could have been reasonably fun. The mazes aren't terrible. You can play in a very non-linear fashion. There's a good bit of real estate to explore. There are a variety of pickups. Things like that are all wins.

But since they didn't finish it...

Who knows how it could have turned out in the end, but the version you can play probably wouldn't be especially interesting to most people. Still, you CAN play through the entire game if you're curious about it. So it's not a total loss.
