Retro gaming is a passion for many, but as the years go by, game cartridges, discs, and consoles start to show signs of wear and tear. Dust, corrosion, failing components, and cracked plastic can turn a once-functional system into a useless relic. The good news is that many common retro gaming issues can be fixed with simple repairs.
This guide will cover step-by-step methods to clean, repair, and restore game cartridges, discs, and consoles, bringing them back to life and ensuring they last for years to come. Whether you’re dealing with a non-working NES cartridge, a yellowed SNES console, or a disc that won’t load, here’s everything you need to know to restore your retro gaming collection.
Essential Tools and Materials for Repairing Retro Games and Consoles
Before starting any repair, it’s important to have the right tools. Here are some essentials for fixing and maintaining your retro collection:
Security Screwdrivers – Many consoles and cartridges use proprietary screws. A 3.8mm bit is needed for NES, SNES, and Genesis cartridges, while a 4.5mm bit is used for consoles.
Isopropyl Alcohol (90% or Higher) – Used for cleaning contacts on cartridges and removing dirt buildup inside consoles.
Cotton Swabs and Soft Brushes – Helps in gently cleaning cartridge pins and circuit boards.
Magic Eraser and Plastic Polish – Useful for removing dirt, scuffs, and scratches from plastic surfaces.
Silica Gel Packets – Helps prevent moisture damage when storing games and consoles.
Multimeter – Used for testing voltage and diagnosing electrical problems in consoles.
Replacement Batteries (CR2032 or CR1616) – Needed for games that use internal save batteries (e.g., Pokémon on Game Boy).
How to Clean and Repair Retro Game Cartridges
Cartridge-based games, like those for NES, SNES, Sega Genesis, and Game Boy, are built to last, but over time, dust, oxidation, and corrosion on the contacts can cause them to stop working.
Step 1: Cleaning the Cartridge Contacts
1️⃣ Open the cartridge – If a game isn’t working, the first step is to open it using a 3.8mm security bit screwdriver.
2️⃣ Inspect the contacts – Look for dirt, oxidation, or corrosion on the gold pins.
3️⃣ Clean with isopropyl alcohol – Use a cotton swab dipped in 90%+ isopropyl alcohol to scrub the contacts.
4️⃣ Use a Magic Eraser or fiberglass pen for stubborn grime – If alcohol alone doesn’t work, a light rub with a Magic Eraser or a fiberglass pen can remove oxidation.
5️⃣ Reassemble and test – Put the cartridge back together and test it in your console.
⚠️ What to Avoid: Never use water or household cleaners on cartridge pins, as they can leave residues that interfere with the connection.
Step 2: Replacing a Dead Save Battery
Many older cartridge-based games, especially Game Boy, SNES, and Sega Genesis RPGs, use internal batteries to save progress. If your game no longer saves, the battery is likely dead.
1️⃣ Open the cartridge – Use a security bit screwdriver to remove the screws.
2️⃣ Locate the battery – It will be a small coin-cell battery (usually CR2032 or CR1616) held in place by metal tabs.
3️⃣ Desolder or tape a new battery in place – The best method is to desolder the old battery and solder a new one, but electrical tape can work in a pinch.
4️⃣ Reassemble and test the save function.
⚠️ What to Avoid: Avoid touching the circuit board with bare fingers, as oils can cause corrosion over time.
How to Repair Scratched Game Discs (PlayStation, Dreamcast, GameCube, Xbox, etc.)
Unlike cartridges, discs are more fragile and can stop working due to scratches, smudges, or disc rot.
Step 1: Cleaning the Disc
1️⃣ Use a microfiber cloth – Always clean in a straight line from the center outward, never in circles.
2️⃣ Apply isopropyl alcohol or a lens-cleaning solution – This removes fingerprints and smudges.
3️⃣ Use a soft-bristle toothbrush for dirt in the edges – Be gentle to avoid scratching.
Step 2: Fixing Scratched Discs
For light scratches, use toothpaste or plastic polish:
1️⃣ Apply a small amount of toothpaste (non-gel) or plastic polish to the disc.
2️⃣ Rub in straight lines with a microfiber cloth.
3️⃣ Wipe clean and test in your console.
For deep scratches, a professional resurfacing machine (such as those found in game stores) may be required.
⚠️ What to Avoid: Never use sandpaper, metal polish, or rough cloths, as they can destroy the disc’s reflective layer.
How to Fix Common Console Issues
Over time, retro consoles develop issues like power failures, graphical glitches, and controller problems. Here’s how to fix some of the most common problems.
Step 1: Fixing a Console That Won’t Power On
1️⃣ Check the power adapter – Use a multimeter to test if the adapter is supplying the correct voltage.
2️⃣ Inspect the power port – Dust and debris can prevent a proper connection.
3️⃣ Open the console and check for blown capacitors – Swollen or leaking capacitors need to be replaced.
Step 2: Fixing a Console That Displays a Distorted Image
1️⃣ Check video cables – Replace old RF cables with composite or RGB cables for better quality.
2️⃣ Clean the cartridge slot (for cartridge-based systems) – A dirty slot can cause glitched graphics.
3️⃣ Reseat or replace the graphics chip (for older disc-based systems) – If a PlayStation or Dreamcast has graphical glitches, overheating or chip damage may be the cause.
Step 3: Cleaning and Whitening Yellowed Consoles
Many SNES, Game Boy, and other older consoles turn yellow due to plastic oxidation. This can be reversed with retrobrighting, a process that restores the original color.
1️⃣ Disassemble the console – Remove all electronic components.
2️⃣ Apply hydrogen peroxide cream (40 volume developer) – Coat the yellowed plastic with hydrogen peroxide and place it in a plastic wrap.
3️⃣ Expose to UV light (or sunlight) for 6-12 hours – Check periodically to ensure it’s not over-brightened.
4️⃣ Rinse and reassemble.
⚠️ What to Avoid: Avoid strong bleach, as it can damage the plastic permanently.
