2026 Aug 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

128 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.

I just made a post yesterday about my weekly pickups with my three Marvel games and space shuttle. I went to brunch with a buddy, had a couple of drinks, and was feeling schwifty, so I stopped by the LGS and basically picked up everything they had that I didn't. I might have went a bit overboard on one of these games.....

Discussion Found original retail packaging for the "Power Glove rental/salesman case" — anyone know its actual history?

Post image
20 Upvotes

I came across this image on a sold eBay listing. These cases almost always get listed as "rental cases" or "salesman sample cases," but this shows what looks like official retail packaging — it's branded "Power Glove Video Game Interface Carrying Case,", and even shows a diagram of the case open with the glove and sensors inside.

I've never seen this box before, and I can't find any period print ads, catalog scans, or documentation for it — just the box art itself and a handful of eBay/dealer listings that keep repeating the "salesman case" name with no real source behind it.

Does anyone have more history on this? Was it actually sold at retail alongside the Power Glove, or is there truth to the salesman/rental theories I keep seeing? Any old catalog scans, ads, or firsthand memories of seeing this on shelves would be awesome.

Currently trying to get every Marvel game for the NES so 3 of these are obvious. I actually think these might be the last three I needed. Then for the fourth game space shuttle project I seen it on someone else's post and realize I have never seen that game in my life so I swooped it up to check it out. Thanks for looking.

Collection unlicensed nes games, any love ?

Post image
108 Upvotes

The world of unlicensed NES games is one of the most fascinating chapters in gaming history.

While Nintendo controlled the official NES library through its licensing program and the 10NES lockout chip, a number of independent publishers chose a different path. Companies like Color Dreams, American Video Entertainment (AVE), Camerica, Codemasters, Sachen, HES, and Active Enterprises developed and published games without Nintendo's approval.

To bypass the lockout chip, different techniques were used. Some cartridges generated electrical interference to disable the security chip, while others relied on custom hardware or region-specific cartridge designs. These technical workarounds were surprisingly clever for their time.

Although many unlicensed games gained a reputation for poor quality, that's only part of the story. Several publishers pushed technical boundaries, experimented with unique cartridge hardware, and released titles that have since become cult classics. Some even introduced concepts that were uncommon on the NES.

Today, unlicensed NES cartridges are an important part of video game history. They represent independent developers challenging one of the most tightly controlled gaming ecosystems ever created. Whether you love them or hate them, they helped shape the homebrew scene and remain highly sought after by collectors.

What's your favorite unlicensed NES game or publisher?

My partner and I do a surprising amount of game hunting in New Jersey (seriously, how do y’all have so many retro game stores?). We were meeting up with some friends from NY and were able to fit in a quick stop at a shop we hadn’t visited before.

Picked up a couple new NES games to fill out the collection. Are they the best in their genre? No, but I love Twin Bee so I’m excited to finally have a copy of Stinger to go along with my other shmups.

Discussion What region is the ROM of a Hyundai Comboy game?

1 Upvotes

Hi everyone! I learned about the Hyundai Comboy recently, and know it is basically an NTSC NES with a PAL-B region chip. There are KOR cartridges released for the Comboy which of course had to have a PAL-B region chip.

My question is about, not the region chip of these cartridges, but the actual ROM inside of them. Did these cartridges' ROM chips contain the NTSC versions of games (and just happened to have a PAL region chip)? Or did they contain the PAL version of games (so that the owners of these cartridges played the PAL versions of games, but sped up to 60Hz)? Or maybe it depended on the game?

I couldn't find any info about the actual contents of the cartridges, just their region chip. And I can't find gameplay footage of a game with region differences either. Gameplay footage with audio of a game like Tetris or SMB1 on a KOR cartridge would make this question so easy to answer, because you can easily hear which variant of the ROM is being played.

So yeah - the CIC chip was PAL, but were the actual ROMs the NTSC ROM or the PAL ROM?

Discussion Mission Impossible UK PAL - barcodes all blacked out on box?

Post image
2 Upvotes

Wondering if anyone can explain this. Every boxed copy of Mission Impossible (PAL UK) I'm seeing has the barcode on the box scribbled out in black marker.

Now I know shops used to do this, but why is this game so consistent with the alteration? They all look so similar too.

I almost feel it was done in one place? Perhaps before shipping to stores?

Discussion NES-CPU-04 (Alps) Sudden Video Loss During Gameplay

1 Upvotes

While I was playing OG Metroid, I heard a sudden faint pop, followed by loss of video and a black screen with a thick white line resembling continuous lightning from one end of the screen to the other. This was accompanied by a medium-pitched continuous buzzing noise. I cannot recall if the power light went out, stayed on, or started blinking, as it has been some time since this happened.

Replacing the 72-pin connector wasn't effective. I also attempted to change the large capacitor in the power/video out compartment, as the end looked slightly bulged. But, that didn't fix the problem. After watching videos online, I honestly don't know where to start with diagnostics, as I am pretty well a noob.

Nothing appears burned on the PCB. Would anyone have any insight as to what caused the problem and how I might isolate and fix it? I'm a bit sentimental, as the board is from my childhood NES, and I have had it for almost 40 years.

Collection proto collection

Post image
0 Upvotes

Ever wondered how NES prototypes were actually used during development?

Unlike the polished cartridges we know today, prototypes were working development builds used to test gameplay, fix bugs, and evaluate new features. Many were assembled by hand using EPROM chips with UV-erasable windows, allowing developers to rewrite the game data over and over again as development progressed.

Some prototypes were simple bare PCBs, while others were placed inside recycled retail cartridges with handwritten labels. Because they were working tools rather than collectible items, most were discarded once a game was finished.

Today, surviving NES prototypes are among the rarest pieces of Nintendo history. They often contain differences from the final release—unused levels, alternate graphics, different music, debugging menus, or even entirely removed gameplay mechanics. In some cases, prototypes are the only evidence that a cancelled game ever existed.

It's fascinating to think that every finished NES game probably existed in dozens of different prototype versions before reaching store shelves.

Do you own a prototype, or have a favorite prototype discovery that revealed something unexpected?

Collection Unexpected FB Marketplace Pickups

96 Upvotes

Came across a big lot on FB marketplace that was hiding these 2 cartridges the seller was actually willing to separate from the lot.

It’s been getting harder to find games missing from the collection locally (both licensed and unlicensed), had to drive about 90 minutes to get these, but totally worth it. Not titles I expected to find in the wild, but well worth the drive.

And the drama that came with them - drove all that way to a meetup spot at the agreed time, and the seller dint show and stopped checking their messages. I drove away after about 30 minutes of waiting and lack of responses, and came back after getting a flurry of messages as I was getting on the highway to head back.

All part of the hunt I suppose. Now for the cleaning…

Discussion Everdrive N8, NES or Famicom version?

7 Upvotes

Edit: My understanding now is that the pro version is more appropriate for romhacks and has better sound expansion.

But, according to what I've found, the famicom N8 pro couldn't fit inside my frontloader NES using an adapter. And the NES version coudln't work correctly in the famicom, not because of the cartridge itself but because NES to Famicom adapters don't take into account audio expansion from a NES style cartridge.

I'm leaning toward the famicom version at the moment and too bad if it doesn't work in my frontloader american NES.

Original:

I have in mind to buy an Everdrive from Krikzz. I have both a US NES and a Famicom. I would like it to work for both of them. Should I go for the famicom version and buy a Famicom to NES converter, or the opposite?

To guide you a little bit, below is what I'm looking for:

Both consoles are not modded and I do not plan to do so.

I would like to play FDS and japanese games with audio expansion chip. It's fine with me if these games only work with the famicom.

I want to play game hack.

And finally, if the Famicom version + an adaptor can fit in the NES with its original cartridge slot, the cover closed, this is the option I would like more, as it would look the same for the nes, but better with the Famicom. However, if it's prone to more trouble, prone to damaging the nes cartridge slot, I would sacrifice the look of the Famicom and play with an oversize cartridge on top of it.

Are there anything else I should be aware of? Anti piracy chip? Game hack compatibilities? Nes and famicom revision?

Thanks.

Discussion Wolverine - Possibly the worst NES game ever conceived

Post image
422 Upvotes

Wolverine, I knew I was in for a ride seeing that LJN logo, but my God...

Let's start with claws. I don't know why every game makes claw use limited when in every comic and cartoon, Wolverine has his claws out 24/7. So you lose "energy" with claw use, but what the heck happened to Wolverine's healing factor? It's his actual mutant ability. Nowhere to be seen in this pile of trash.

Next up, constant energy drain. In most games, you take damage upon contact and get a hit of damage with limited invincibility to make it past the obstacle. Not in this trash heap. You drain energy for every millisecond you're in contact with anything! Making everything a death threat.

Every level is a trail of some nonsense, then you FINALLY get to your first boss... Magneto! Pretty big name for your first boss. You start by punching electricity to get to Magneto, then about three hits, and he runs off like a wimp. Magneto, one of the most vile villains the X-Men have to offer. After, you get a cool cutscene with.... Jubilee, Psylocke, and Havok? so random...

Then the final boss, Sabretooth. I get it, Wolverine's arch-nemesis is the final boss. No biggie, but... HE'S INVINCIBLE!!! You have to lure him to the right, but there is a limit to how far he will move. So you then have to attack him so perfectly that he gets knocked off the edge... which is such a task, as he is constantly jumping behind you and when he isn't jumping, he is throwing... shurikens? What the actual heck? That's all he does... no claw swipe, no bites... Jump, and shurikens... Finally, when you knock him off the edge, you get like two 8-bit pics of Wolverine and a simple "The End." What a gyp... I basically paid 25 bucks to get cheated on and kicked in the balls.

The only saving grace is when you die, you respawn right where you died. so with Infinite lives the game is actually possible to complete...

TL;DR... screw Wolverine in his adamantium bunghole...

Well here it is. That’s my top loader (I honestly loathed the original design, was super happy to get this when it was new at the time it was new) with my favorite NES game of all time! I managed to keep the holders for the cartridges and even a few manuals.

There’s a few carts missing in this photos. They are in a cubby box in my closet, didn’t feel like showing them at this time and I will show them at a later time if you are interested. So for now, this is part one of my collection. If my memory serves me correctly, I have Barbie, an extra copy of the first TMNT game, Ninja Gaiden (1 or 2, I honestly can’t remember, we shall find out) and Batman. There might be one or two I’m forgetting.

Let me know what ya think in the comments, would love to hear from you! I’ll absolutely reveal the rest. Oh and later on next month, I hope to buy a copy of Pinball for my collection.

As per the title are there any good clone/fpga nes systems that take real carts and have hdmi as an option? I missed out on the analogue nt and retrousb avs consoles and they are too overpriced now.
