Why Your Retro Console Won’t Read Games: Dirty Pins, Bad Lasers, Scratched Discs, and Common Fixes

Summary

Few retro gaming problems are more frustrating than putting in a game, powering on the console, and getting nothing.

Maybe your NES blinks. Maybe your SNES shows a black screen. Maybe your Nintendo 64 acts like no cartridge is inserted. Maybe your PlayStation 2 spins and stops. Maybe your GameCube says the disc could not be read. Maybe your Wii refuses a game it played perfectly years ago. Maybe your Xbox 360 gives you the dreaded “Open Tray” behaviour.

The good news is that a console not reading games does not always mean the console is dead. Sometimes the problem is simple: dirty cartridge contacts, oxidation, a scratched disc, fingerprints, a weak connection, a bad cable, a dead save battery creating confusion, or even a wrong-region game.

The bad news is that sometimes the problem is deeper: worn cartridge slots, bent pins, failing disc lasers, bad capacitors, damaged disc drives, counterfeit cartridges, disc rot, or hardware failure.

This guide breaks down why retro consoles stop reading games, what you can safely check at home, what you should avoid doing, and when it is time to stop poking at it before you make things worse.

Power Up Gaming tests used games and consoles before sale, checks authenticity, professionally refinishes many CD/DVD-format games, keeps strict standards for Blu-ray format games, replaces batteries in battery-backed cartridge games before they hit the sales floor, and carries practical replacement cables and power supplies when available. If you are not sure whether the problem is the game, the console, the cable, the power supply, or the disc, we can help you narrow it down.

First Question: Is It the Game or the Console?

Before you clean anything, open anything, or start threatening your console with a screwdriver, start with the most basic question:

Is the problem the game, or is the problem the console?

Test this in the simplest way possible.

If one game will not work, try another game that you know works.

If multiple games fail, the console may be the issue.

If only one cartridge or disc fails, the game may be the issue.

If the console reads some games but not others, you may be dealing with:

• Dirty cartridge contacts

• Scratched discs

• Weak laser

• Region lock issue

• Specific format issue

• Bad cartridge board

• Bad disc manufacturing

• Early signs of hardware failure

For disc-based consoles, PlayStation and Xbox both recommend trying more than one disc as part of troubleshooting because it helps separate a bad disc from a console or drive issue. Sony’s PS4 disc troubleshooting recommends cleaning the disc with a soft cloth and trying another game, Blu-ray disc, or DVD, while Xbox support similarly recommends checking the disc for damage and trying troubleshooting steps before assuming the console is dead. (PlayStation)

Do not skip this step.

A lot of people assume the console is broken when the game is the problem.

A lot of other people assume the game is bad when the console is the real gremlin.

Cartridge Games vs Disc Games

Retro consoles usually fail to read games in two very different ways.

Cartridge systems have contact problems.

Disc systems have optical drive problems.

That is oversimplified, but it is a good starting point.

Cartridge-Based Systems

These include systems like:

• NES

• SNES

• Nintendo 64

• Game Boy

• Game Boy Color

• Game Boy Advance

• Sega Genesis

• Sega Master System

• Sega Game Gear

• Atari 2600

• TurboGrafx-16

• Neo Geo

• Many other older systems

Cartridge problems usually involve:

• Dirty contacts

• Oxidation

• Bent cartridge slot pins

• Worn connector

• Loose cartridge fit

• Damaged PCB

• Broken solder joints

• Counterfeit cartridge issues

• Dead save battery, depending on symptom

• Wrong-region game

• Console pin connector failure

Disc-Based Systems

These include systems like:

• PlayStation 1

• PlayStation 2

• PlayStation 3

• PlayStation 4

• PlayStation 5

• Sega CD

• Sega Saturn

• Dreamcast

• GameCube

• Wii

• Wii U

• Original Xbox

• Xbox 360

• Xbox One

• Xbox Series X

Disc problems usually involve:

• Scratched discs

• Dirty discs

• Cracked discs

• Disc rot

• Label-side damage

• Dirty laser lens

• Weak laser

• Misaligned laser

• Failing spindle motor

• Failing drive belt

• Worn drive mechanism

• Bad optical drive board

• Incorrect disc format

• Wrong region

• System software issue on newer consoles

The first step is knowing which world you are in.

Dirty pins and bad lasers are different monsters.

Why Cartridge Games Stop Reading

Cartridge games rely on physical metal contacts.

When you insert a cartridge into a console, the metal contacts on the game need to connect properly with the pins inside the console. If that connection is dirty, oxidized, loose, bent, or damaged, the console may not read the game correctly.

Symptoms can include:

• Black screen

• Blinking power light

• Glitched graphics

• Frozen logo

• Game starts then crashes

• Random resets

• Audio glitches

• Save data not loading

• Game only works if inserted a certain way

• Game works after multiple tries

• Game works in one console but not another

The cartridge itself might be fine. The console might be fine. The issue might just be a poor connection.

Unfortunately, that poor connection can be incredibly annoying.

Dirty Cartridge Contacts

Dirty cartridge contacts are one of the most common reasons old games do not boot.

Over time, contacts can collect:

• Dust

• Dirt

• Skin oil

• Smoke residue

• Oxidation

• Corrosion

• Old cleaning residue

• Debris from the console slot

• Moisture damage

• Grime from decades of storage

Even if the cartridge looks clean on the outside, the contacts can still be dirty.

A cartridge stored loose in a basement, garage, bin, or box for 25 years has had plenty of time to become a tiny archaeological site.

How to Safely Clean Cartridge Contacts

For most cartridge games, a careful contact cleaning can help.

A common safe method is:

1. Turn the console off.

2. Remove the cartridge.

3. Use high-percentage isopropyl alcohol on a cotton swab.

4. Gently clean the cartridge contacts.

5. Use a dry swab to remove leftover moisture.

6. Let the cartridge dry fully.

7. Try the game again.

Use only a small amount of alcohol. Do not soak the cartridge. Do not pour liquid into the cartridge. Do not use harsh cleaners. Do not use water.

If the contacts are very dirty, you may need several passes.

The swab may come away black or grey. That is normal. That is the grime giving up its villain arc.

Do Not Blow Into Cartridges

We all did it.

We all felt like it worked.

We all have childhood memories of blasting into an NES cartridge like we were trying to revive a fainting raccoon.

But blowing into cartridges is not a good repair method.

The reason it sometimes seemed to work is often because removing and reinserting the cartridge improved the connection. Your breath was not the magic. The reseating was. iFixit’s 2024 explainer on the old cartridge-blowing myth describes the effect as largely confirmation bias and notes that the issue was usually the connection between the cartridge and console, not something fixed by breath. (ifixit.com)

Blowing into cartridges can introduce moisture, which can make corrosion worse over time.

So yes, it was nostalgic.

No, it was not wise.

Retro gaming is full of rituals. This one can retire.

Dirty Console Cartridge Slots

Sometimes the cartridge is clean, but the console slot is dirty.

This is especially common with:

• NES

• SNES

• Nintendo 64

• Genesis

• Game Boy systems

• Atari systems

• Consoles stored open or uncovered

• Consoles from smoky or dusty homes

Cleaning a console slot is trickier than cleaning a cartridge.

You can sometimes use a proper cartridge slot cleaning tool, cleaning card, or carefully cleaned sacrificial cartridge, but you need to be careful. You do not want to bend pins, leave fibres inside the connector, or flood the slot with liquid.

If the console slot is very dirty or corroded, it may need professional cleaning or repair.

Bent Pins and Worn Cartridge Connectors

If cleaning does not help, the connector itself may be worn or damaged.

Common symptoms of worn or bent pins include:

• Games only work if inserted at an angle

• Games only work when pushed down or pulled forward

• Frequent black screens

• Games work after many attempts

• Different cartridges behave inconsistently

• Console is picky about some games

• Visible bent pins inside the slot

The NES front loader is famous for connector issues because of its loading mechanism. The cartridge is inserted and pushed down, which adds extra mechanical wear over time.

Sometimes the connector can be cleaned or adjusted. Sometimes it needs replacement.

Do not jam objects into the slot trying to bend pins back unless you know what you are doing.

That path leads to sadness and tiny metal regret.

Oxidation and Corrosion

Oxidation is common on old cartridge contacts. Light oxidation can sometimes be cleaned. Heavy corrosion is more serious.

Watch for:

• Green corrosion

• White crust

• Rust-coloured staining

• Pitting on contacts

• Battery leakage

• Moisture damage

• Sticky residue

• Discoloured board traces

Corrosion can damage the cartridge PCB and may not be fully repairable if traces or chips are affected.

If a cartridge has obvious corrosion, it should be inspected carefully before use. You do not want to transfer corrosion or debris into a clean console slot.

Fake or Reproduction Cartridges Can Cause Read Problems

If a cartridge is fake, reproduction, or poorly made, read problems may not be dirt-related at all.

Fake cartridges can have:

• Cheap boards

• Poor soldering

• Low-quality flash memory

• Incorrect voltage handling

• Bad save chips

• Bad shell fit

• Poor contact alignment

• Inconsistent booting

• Save failure

• Compatibility problems

Some fake games work in one console and not another. Some boot but crash. Some save for a while, then fail. Some have weird glitches. Some are just built badly.

Power Up Gaming has never knowingly or willingly sold a fake game. We are careful with authenticity checks and keep fake games in-store as reference tools for staff education.

If your cartridge looks suspicious and also does not boot reliably, authenticity should be part of the diagnosis.

Dead Save Batteries Usually Do Not Stop the Game From Booting

A dead save battery usually causes save problems, not boot problems.

If a battery-backed game starts normally but will not save, that is probably a battery issue.

If a game will not boot at all, the battery is usually not the first suspect.

That said, some cartridges with battery leakage or bad battery repair attempts can have board damage that affects more than saving.

At Power Up Gaming, battery-backed games have their batteries replaced before they go onto the sales floor. That gives customers years of save functionality without relying on original decades-old batteries.

For customer-owned games, we replace batteries in Nintendo and Sega Genesis games, but existing saves cannot be guaranteed during replacement.

Wrong-Region Cartridge Games

Sometimes a game does not read because it is not meant for your console region.

For Canadian buyers, this often means confusion between:

• NTSC-U/C

• Japanese NTSC-J

• PAL

• European versions

• Region-modified consoles

• Physical cartridge shape differences

• Lockout chips

• Console region locks

Some systems are region-free. Some are not. Some games physically fit but will not boot properly. Some require adapters or modifications.

If you bought a game online and it will not boot, check the region before assuming the cartridge is broken.

The game might be fine.

It just might not be from your neighbourhood.

Why Disc Games Stop Reading

Disc-based consoles are a different problem.

Instead of metal cartridge contacts, disc systems rely on an optical drive. The console uses a laser to read data from the disc. If the disc is scratched, dirty, cracked, warped, or rotting, the laser may struggle. If the laser is dirty, weak, misaligned, or failing, the console may struggle even with good discs.

Symptoms can include:

• “Disc could not be read”

• “Please insert a disc”

• Console spins then stops

• Clicking noises

• Grinding noises

• Long loading times

• Game freezes during loading

• Cutscenes stutter

• Music skips

• Game crashes at the same point

• Console reads CDs but not DVDs

• Console reads DVDs but not games

• Console reads some formats but not others

• Console only reads discs after warming up

• Console reads one game but not another

Disc read issues can be caused by the disc, the console, or both.

Start With the Disc

Before blaming the console, inspect the disc.

Look for:

• Fingerprints

• Smudges

• Deep scratches

• Circular scratches

• Cracks near the centre ring

• Disc rot

• Pinholes

• Label-side damage

• Warping

• Cloudiness

• Peeling

• Heavy resurfacing marks

Sony recommends cleaning discs with a soft, clean cloth when troubleshooting PS4 disc reading problems, and Xbox support warns not to use solvents when cleaning discs. (PlayStation)

A clean disc should be tested again after cleaning.

A dirty disc is not always a dead disc.

Sometimes it is just gross.

How to Clean a Game Disc Safely

Use a soft microfiber cloth.

Wipe gently from the centre of the disc outward toward the edge.

Do not wipe in circles.

Do not use:

• Harsh solvents

• Window cleaner

• Paper towels

• Abrasive cloths

• Toothpaste

• Magic erasers

• Household cleaners

• Random “life hack” mixtures

The internet is full of disc-cleaning advice that sounds like it was written by someone who hates discs.

Be gentle.

Scratched Discs

Scratches affect different disc formats differently.

Older CD and DVD-based games can sometimes be professionally refinished if the damage is on the readable surface and not too deep.

This can apply to games for systems like:

• PlayStation 1

• PlayStation 2

• Original Xbox

• Xbox 360

• GameCube

• Wii

• Sega CD

• Sega Saturn

• Dreamcast

Power Up Gaming uses professional disc refinishing equipment for CD/DVD-format games and has very high condition standards.

But refinishing is not magic.

It cannot fix:

• Disc rot

• Cracks

• Pinholes through the data layer

• Severe label-side damage

• Warped discs

• Deep gouges through critical layers

• Missing data

• Blu-ray format discs we do not refinish

Blu-ray Format Discs Are Different

Blu-ray format games need stricter standards.

This includes:

• PlayStation 3

• PlayStation 4

• PlayStation 5

• Xbox One

• Xbox Series X

• Wii U

At Power Up Gaming, Blu-ray format games need to be spotless when we sell them. We do not treat marks on Blu-ray format games like casual wear.

Why? Blu-ray discs are built differently from older CD and DVD formats. They have a hard coating, but the data layer is closer to the surface. Damage can be more concerning, and resurfacing Blu-ray discs is not handled the same way as older formats.

If your PS4, PS5, Xbox One, Xbox Series X, PS3, or Wii U disc has marks, that can absolutely matter.

Disc Rot and Label-Side Damage

Some disc problems cannot be cleaned or resurfaced.

Disc rot can appear as:

• Bronze discolouration

• Pinholes

• Cloudy patches

• Data layer breakdown

• Light passing through damaged areas

• Flaking or peeling

• Read errors that get worse over time

Label-side damage can also be serious, especially on CDs where the data layer can be closer to the label side.

If the data layer is physically damaged, a resurfacer will not bring it back.

That is not a scratch problem.

That is a “the information is gone” problem.

Dirty Laser Lens

If multiple clean discs fail, the console’s laser lens may be dirty.

Dust, smoke residue, and debris can affect the laser’s ability to read discs.

This can happen with:

• PS1

• PS2

• GameCube

• Wii

• Dreamcast

• Saturn

• Original Xbox

• Xbox 360

• PS3

• Other disc systems

A dirty lens can sometimes be cleaned, but you need to be careful. Some systems are easier to access than others. Some require disassembly. Some are not beginner-friendly.

Do not scrub the lens. Do not use too much liquid. Do not press hard. The lens assembly is delicate.

If you are not comfortable opening the system, stop.

There is no shame in not turning your console into a table full of screws and regret.

Weak or Failing Lasers

Lasers wear out.

A weak laser may show symptoms like:

• Reads some discs but not others

• Reads CDs but not DVDs

• Reads DVDs but not dual-layer discs

• Reads games only when the console is cold

• Reads games only after several attempts

• Freezes during loading

• Makes repeated seeking noises

• Takes longer than normal to load

• Fails at the same point in a game

The PS2 is especially known for laser and disc-read issues across different models. Xbox 360 drives can also develop read problems over time. GameCube and Wii lasers can weaken. Dreamcast GD-ROM drives can wear. Original Xbox drives can be picky depending on drive model.

Laser adjustment is sometimes discussed online, but it is not a casual fix. Adjusting potentiometers without understanding what you are doing can shorten laser life or make things worse.

Sometimes a laser needs cleaning.

Sometimes it needs replacement.

Sometimes the drive has deeper issues.

Failing Disc Drive Mechanics

Not every disc problem is the laser.

The console also has mechanical parts.

Problems can include:

• Worn drive belt

• Bad spindle motor

• Bad tray motor

• Weak eject mechanism

• Dirty rails

• Stuck tray

• Misaligned lid switch

• Broken gear

• Faulty disc clamp

• Bad drive board

• Damaged ribbon cable

Symptoms can include:

• Tray will not open

• Tray opens then closes

• Disc does not spin

• Disc spins unevenly

• Clicking or grinding

• Console does not detect the lid is closed

• Disc slips

• Drive makes noise but does not read

If you hear grinding, repeated clicking, or the disc is not spinning properly, stop forcing it.

A console that cannot read discs is annoying.

A console that scratches discs while failing is worse.

Console-Specific Read Problems

NES Won’t Read Games

Common causes:

• Dirty cartridge contacts

• Dirty 72-pin connector

• Worn or bent connector

• Lockout chip issues

• Bad cartridge

For handhelds, power issues can look like read issues. If the system is underpowered, it may behave unpredictably.

Sega Genesis Won’t Read Games

Common causes:

• Dirty cartridge contacts

• Dirty console slot

• Wrong power supply

• Dirty power switch

• Region mismatch

• Oxidation

• Bad cartridge board

• Worn connector

Safe things to try:

• Clean cartridge contacts

PlayStation 1 Won’t Read Discs

Common causes:

• Scratched disc

• Dirty lens

• Weak laser

• Worn spindle

• Bad lid switch

• Console age

• Disc format issue

Safe things to try:

• Clean the disc

• Try another disc

• Try an audio CD

• Check if the disc spins

• Try a blue-bottom CD-based PS2 game if you have one

• Try a silver DVD-based PS2 game

• Try a PS1 game

• Try a DVD movie

• Check if the issue is format-specific

The PS2 can be picky because it reads multiple disc types. If it reads some formats but not others, that gives you a clue.

GameCube Won’t Read Discs

Common causes:

• Scratched mini disc

• Dirty lens

• Weak laser

• Failing spindle motor

• Lid switch issue

• Disc damage

• Region mismatch

Safe things to try:

• Clean the disc carefully

• Try another GameCube game

• Listen for spinning

• Check if the lid switch is engaging

• Do not force the mini disc

GameCube discs are small and collectible. Do not experiment aggressively with them.

Wii Won’t Read Discs

Common causes:

• Dirty disc

• Scratched disc

• Dirty lens

• Weak laser

• Dual-layer disc issues

• Drive mechanism failure

• Wrong disc orientation

• Region mismatch

Nintendo’s Wii disc-read troubleshooting recommends ejecting the disc, powering the system off, making sure the Wii is placed correctly, waiting, powering it back on, and verifying the disc is inserted correctly. (Nintendo Support)

Safe things to try:

• Clean the disc

• Try another Wii game

• Try a GameCube game if the Wii model supports it

• Check disc orientation

• Power cycle the console

• Avoid forcing discs into a slot-loading drive

Some Wii models can read GameCube discs, and some cannot. Check the model.

Dreamcast Won’t Read Discs

Common causes:

• Scratched GD-ROM

• Dirty lens

• Weak laser

• Try a DVD movie

• Check if the tray opens and closes properly

• Restart the console

• Avoid forcing the tray

Xbox support recommends checking discs for damage and not using solvents on discs during troubleshooting. (Xbox Support)

If multiple known-good discs fail, the drive may need repair or replacement.

PlayStation 3, PS4, PS5, Xbox One, and Xbox Series X Won’t Read Discs

These systems are newer than classic retro, but they are now part of the used-game conversation.

Common causes:

• Dirty disc

• Damaged Blu-ray disc

• Wrong disc orientation

• Dirty drive

• Failing optical drive

• Software issue

• Database or system issue

• Unsupported disc type

• Physical drive damage

Sony’s PS5 disc troubleshooting includes checking disc orientation, especially when the console is vertical, and PS4 troubleshooting recommends cleaning the disc and trying another disc type. (PlayStation)

Safe things to try:

• Clean the disc

• Check disc orientation

• Try another game

• Restart the console

• Check for updates

• Follow official safe mode troubleshooting if appropriate

• Do not insert damaged discs

For Blu-ray format games, Power Up Gaming’s standard is simple: clean, spotless discs only.

Bad Power Supplies Can Cause Weird Read Problems

Sometimes a console seems like it will not read games, but the real issue is power.

A weak, incorrect, or failing power supply can cause:

• Random resets

• Black screens

• Disc drive not spinning properly

• Cartridge games not booting consistently

• Video cutting out

• Audio problems

• Console freezing

• Controller issues

• Intermittent behaviour

This is especially important with retro consoles because many use specific power supplies.

Do not assume a power supply is safe just because it fits.

Wrong voltage, wrong polarity, wrong amperage, or AC/DC mismatch can damage hardware.

Power Up Gaming carries replacement power supplies when available and can help identify the correct cable or adapter for many systems.

Bad AV Cables Can Look Like Read Problems

Sometimes the game is working, but you cannot see it.

A bad AV cable, wrong input, loose connector, or modern TV compatibility issue can make a working console look dead.

Before assuming the console is not reading games, check:

• TV input

• AV cable

• HDMI adapter

• Power supply

• Display compatibility

• 4:3 or input settings

• Whether the console has sound but no picture

• Whether the console works on another TV

This is especially common with older systems connected to modern TVs using adapters.

A console can be reading the game just fine while your TV is sitting there like, “Absolutely not.”

Region Locking Can Look Like a Broken Game

Wrong-region games can fail to boot or display incorrectly.

Examples:

• PAL game on North American console

• Japanese cartridge on North American console

• Region-locked disc

• Import game needing a modded console

• DLC/account region mismatch on newer systems

If a game you bought online does not work, check the region before assuming the disc or cartridge is bad.

Power Up Gaming’s region locking guide is a good companion to this topic because Canadian gamers often run into PAL, NTSC-J, and NTSC-U/C confusion.

When DIY Cleaning Is Okay

DIY cleaning can be okay when:

• You are cleaning cartridge contacts gently

• You are cleaning disc smudges with microfiber

• You are checking cables and inputs

• You are reseating an N64 Jumper Pak or Expansion Pak

• You are using proper tools

• You are not forcing anything

• You know when to stop

Good beginner steps:

• Clean the cartridge contacts

• Clean the disc

• Try another game

• Try another cable

• Try another power supply only if correct

• Try another TV input

• Check region

• Check required accessories

If the fix is simple, great.

If it is not simple, do not escalate into chaos.

When to Stop

Stop if:

• You hear grinding

• The disc is being scratched

• The power supply smells hot

• You see smoke

• The console sparks

• You see corrosion

• You see liquid damage

• The cartridge slot pins are bent

• The disc drive will not release the disc

• A screw strips

• You are forcing plastic

• You are guessing with power supplies

• You are about to adjust a laser without knowing how

• You are watching a tutorial and thinking, “This seems terrifying”

That feeling is wisdom.

Listen to it.

What Power Up Gaming Does to Reduce These Problems

Power Up Gaming deals with these problems every day.

That is why our used inventory standards matter.

When we sell used games and consoles, we are not just throwing mystery items online and hoping for the best.

Power Up Gaming:

• Tests used consoles before sale

• Tests used games before sale

• Checks cartridge authenticity

• Has never knowingly or willingly sold a fake game

• Keeps fake games in-store for comparison and staff education

• Replaces batteries in battery-backed cartridge games before they go on the sales floor

• Professionally refinishes many CD/DVD-format game discs

• Maintains strict condition standards for Blu-ray format games

• Matches consoles with correct cables and power supplies when available

• Offers warranty support on used products

• Helps customers troubleshoot when something is not working

For online inventory, Power Up Gaming uses stock photos because our inventory is massive and also lives on the retail floor, but we are happy to provide real photos, verify contents, check condition, and answer questions by request.

That combination of testing, inspection, service, and accountability is the difference between a real store and a private “worked last time” listing.

Quick Troubleshooting Checklist

Before assuming the console is dead, check:

• Does the console power on?

• Does it show video?

• Does it have sound?

• Are you on the correct TV input?

• Are you using the correct power supply?

• Are you using the correct AV cable?

• Does another game work?

• Does the problem game work in another console?

• Are cartridge contacts clean?

• Is the cartridge authentic?

• Is the game the correct region?

• Is the disc scratched or dirty?

• Does the console read other discs?

• Does the disc drive spin?

• Does the drive make grinding noises?

• Are required accessories installed?

• Is there corrosion, smoke smell, or water damage?

If you can answer those questions, you are already ahead of most “it does not work” listings online.

Final Thoughts

A retro console that will not read games is not always dead.

Sometimes the fix is as simple as cleaning dirty cartridge contacts, trying another cable, checking the power supply, or cleaning a smudged disc. Sometimes the problem is a scratched disc that can be professionally refinished. Sometimes the issue is a wrong-region game, fake cartridge, missing N64 Jumper Pak, or a TV input problem.

Other times, the console needs real repair. Lasers get weak. Disc drives fail. Cartridge slots wear out. Pins bend. Boards corrode. Old electronics age.

The trick is knowing when to troubleshoot and when to stop.

Power Up Gaming can help customers avoid a lot of these headaches by selling tested used games and consoles, checking authenticity, replacing cartridge batteries before sale, refinishing discs where appropriate, and helping match the right cables and power supplies.

Because retro gaming should feel nostalgic.

Not like you are negotiating with a haunted toaster.

FAQ

Why won’t my retro console read games?

The most common reasons are dirty cartridge contacts, dirty console slots, scratched discs, dirty laser lenses, weak lasers, bad power supplies, wrong-region games, or failing hardware.

Why does my cartridge game show a black screen?

A black screen often means the console is not making a clean connection with the cartridge. Dirty contacts, oxidation, a dirty cartridge slot, bent pins, or a bad cartridge board can all cause this.

Should I blow into my cartridges?

No. Blowing into cartridges can introduce moisture and does not properly clean the contacts. The reason it seemed to work was often because removing and reinserting the cartridge improved the connection. (ifixit.com)

How should I clean cartridge contacts?

Use high-percentage isopropyl alcohol and a cotton swab. Clean gently, use only a small amount of liquid, and let the cartridge dry fully before testing.

Why does my NES blink?
