A shelf full of cartridges and discs can feel permanent. It is not. Save batteries run flat, optical drives wear out, plastic becomes brittle and online services disappear. The good news is that most collections can be kept playable for decades with stable storage, careful handling and a simple testing routine.
This is a practical preservation checklist for people who still want to play their games, not just display them. It covers cartridges, optical discs, saves, consoles and the records that give a collection its history.
Why personal collections matter
The Video Game History Foundation’s 2023 availability study found that only 13% of the classic games in its US sample were still in release. That does not mean the other games have physically vanished, but it shows how heavily access depends on ageing copies, hardware, private collections and specialist archives.
A physical game is also more than its program data. The cartridge shell, disc artwork, manual, map, registration card, price sticker and even a handwritten save note can document how games were sold and played. Preservation therefore means looking after both the playable object and its context.
What actually fails?
Cartridges
Mask ROM chips can remain readable for a very long time, but cartridge contacts become dirty or oxidised, solder joints crack and traces corrode after moisture or battery leakage. Games with battery-backed saves may lose progress when the cell is exhausted. The game itself can still work even when its saves no longer persist.
Optical discs
Scratches, cracks around the centre hub, contamination and deterioration of the reflective or bonding layers can make a disc unreadable. “Disc rot” is often used as a catch-all term, but not every read error is chemical deterioration. A failing laser, misaligned drive or damaged surface can produce similar symptoms.
Magnetic media
Floppy disks and tapes are vulnerable to mould, damaged jackets, magnetic loss and failing drives. Do not repeatedly force questionable media through an unserviced mechanism: a dirty or damaged drive can harm a disk that was previously recoverable.
Consoles and accessories
Capacitors age, belts stretch, lubricants dry, lasers weaken and power supplies drift out of specification. Controller cables split and conductive pads wear. The most carefully stored game is not playable if the only compatible hardware fails.
Digital dependencies
Some physical releases depend on a downloaded patch, installation data, an account or an online entitlement check. A disc or cartridge in the box does not always contain a complete, permanently playable version. Record what each game needs while the service and documentation are still available.
The collector’s preservation checklist
1. Make an inventory before you clean anything
Record the title, platform, region, edition, serial or product code, condition and included items. Photograph the front, back, spine, labels and any existing damage. For valuable pieces, record when and where they were acquired.
This protects provenance and makes gradual deterioration easier to spot. It also helps with insurance and avoids buying duplicate copies. Retromart’s guide to condition labels and new-unsealed stock explains why completeness and sealing are not the same thing.
2. Choose stable storage
- Keep games indoors in a dry, clean room with a reasonably stable temperature.
- Avoid lofts, garages, sheds, radiators, direct sunlight and exterior walls prone to condensation.
- Store boxed games upright and supported rather than crushed under a tall stack.
- Keep discs in correctly sized cases with an intact centre hub.
- Use inert, archival-quality sleeves for loose paperwork and avoid PVC sleeves that can become sticky.
- Leave air around consoles and never store them while damp.
Stability matters more than chasing one perfect number. Repeated swings between hot, cold, damp and dry place stress on paper, adhesives, plastics and metal.
3. Handle games by their strongest surfaces
Hold discs by the outer edge and centre hole. Avoid touching the readable surface. Hold cartridges by the shell rather than the label or contacts. Clean hands are usually safer than gloves for ordinary handling because they provide better grip.
Do not test a cracked disc at high speed. A fracture around the centre can spread inside a drive.
4. Clean conservatively
Start with the least aggressive method. Remove loose dust with a clean air blower or soft brush. Wipe a disc with a clean microfibre cloth in straight lines from the centre towards the edge, not in circles. If further cleaning is needed, use a method appropriate to that exact material.
For cartridge contacts, a small amount of high-purity isopropyl alcohol on a lint-free swab is commonly used, followed by complete drying. Do not soak the board, sand plated contacts or reach for metal polish as a first step. Abrasives can remove the protective surface and create a temporary improvement followed by faster corrosion.
Avoid household window cleaner, scented wipes, furniture polish and adhesive removers unless a conservator has confirmed they are safe for the material. Labels and printed disc surfaces are particularly easy to damage.
5. Plan for save batteries
If a game uses a battery-backed save, note whether it still holds data after the console has been off. Back up important saves before replacing anything. Battery type and polarity vary, and some cartridges use tabs or holders rather than a loose cell.
A professional replacement is sensible for valuable cartridges or anyone without suitable soldering experience. Ask the technician to inspect the board for leakage and corrosion while it is open. A battery holder can make future maintenance easier, but it is a modification and may not suit a highly original collector’s piece.
6. Preserve your saves separately
Memories are often harder to replace than the game. Where supported, copy saves from memory cards or cartridges using reputable hardware and keep more than one backup. Use clear filenames containing the game, region, date and source device.
Test that a copied save can be read before treating it as a backup. Keep one copy away from the console and another on separate storage. Cloud sync can be useful, but it should not be the only copy.
7. Create lawful preservation copies where appropriate
Specialist hardware and compatible optical drives can sometimes create a digital image of media you own. This can help confirm readability and reduce handling of a rare original. Laws and platform terms differ by country, so check the rules that apply to you. Owning a cartridge or disc does not automatically make downloading somebody else’s copy lawful.
Document the original hardware, software version and checksums used. A folder full of unexplained files is much less useful to a future owner or researcher than a verified, well-described backup.
8. Exercise and test the collection
Once or twice a year, sample each storage area rather than trying to play every game. Check for damp smells, mould, corrosion, pest activity, warped cases and leaking batteries. Test valuable or unusual media on known-good hardware.
When a game fails, test methodically:
- Inspect and clean the media safely.
- Try another known-good game in the same console.
- Try the game on another compatible, known-good system if available.
- Record the symptoms before arranging repair.
This distinguishes a media problem from a failing console or power supply.
9. Maintain the hardware that reads the games
Store consoles without batteries in their controllers or accessories. Inspect power supplies and cables for cracks, heat damage and corrosion. Do not rely on an unknown replacement adaptor simply because the plug fits: voltage, polarity, current capacity and regulation all matter.
Optical drives should not be “adjusted” blindly to compensate for read errors. Turning a laser potentiometer without proper diagnosis can shorten component life and mask a mechanical or capacitor fault. Use a repairer who can test the drive and power rails rather than only increasing laser power.
10. Preserve patches and instructions
For games that need updates, downloadable content or online activation, keep a note of the final installed version and which features work offline. Retain official manuals, patch notes and setup instructions where licensing permits. If a console provides a supported system-transfer or backup function, learn how it works before the service is closed.
Do not assume an online store will remain available forever just because it works today.
11. Keep provenance with the object
A receipt, letter, tournament note or developer signature may be historically important. Store provenance separately in an archival sleeve and include a digital copy in the inventory. Never “improve” a rare item by removing stickers or writing until you understand whether they form part of its story.
12. Insure and plan for the next owner
Collections often grow beyond the limit of ordinary home insurance. Check the policy, photograph high-value items and keep purchase evidence. Make sure a trusted person knows where the inventory is stored and what should happen to the collection if you can no longer manage it.
Things that do more harm than good
- Storing games in a hot loft or damp garage to keep shelves tidy.
- Using an eraser, sandpaper or metal polish aggressively on cartridge contacts.
- Running a cracked disc “one last time”.
- Spraying cleaner directly onto labels, screens or circuit boards.
- Replacing components in a rare item without photographing the original condition.
- Throwing away original parts after a reversible repair.
- Trusting one hard drive, one memory card or one cloud account with every backup.
A simple annual routine
| Task | Frequency |
|---|---|
| Check room temperature, damp and sunlight exposure | Whenever seasons change |
| Inspect shelves, cases and batteries for damage | Every 6 to 12 months |
| Test a sample of cartridges, discs and drives | Annually |
| Verify save and media backups | Annually and after every important change |
| Update photographs and valuations | After significant purchases or repairs |
The Retromart verdict
You do not need a museum laboratory to preserve a working collection. Keep it clean, dry, stable, documented and tested. Back up irreplaceable saves, maintain the hardware and intervene only when there is a clear reason. The biggest improvements usually come from boring habits performed consistently.
Most importantly, keep playing the games. Careful use reveals problems early and preserves the knowledge of how the hardware, controllers and software actually work together.
