How to Store Second Hand Japanese Retro Games — Cartridges, Discs and Boxes
Retro Japanese games are three fragile materials in one package: plastic and metal in the cartridge, paper in the manual and spine card, and often a battery that has been quietly running since the 1990s. Each needs different care.
Care by material
| Part | Main risk | What to do |
|---|---|---|
| Cartridge shell & label | UV fading, label lift, sticker residue | Store out of light; never apply price stickers or tape to the label |
| Edge connector | Oxidation causing boot failures | Clean with 99% isopropyl alcohol on a swab; dry fully before use |
| Save battery | Dies after roughly 20–30 years; can leak | Expect a replacement on battery-save titles; store cool and check for leakage |
| Discs | Scratches, disc rot in humid heat | Upright in the case, stable temperature, low humidity |
| Box, manual, spine card | Yellowing, curling, mould | Dry, dark, flat; a desiccant in the storage box |
| Console plastics | UV yellowing of light-coloured shells | Keep out of direct sun — this is why so many surviving units are yellowed |
A storage routine that works
-
Unpack cold parcels slowly
Let a shipment from Japan reach room temperature sealed, so condensation forms outside the box. -
Test before you shelve
Clean the contacts, confirm it boots and confirm whether saves persist overnight. -
Shelve upright, in a dry interior room
Boxes upright, discs upright, nothing stacked bare. -
Add a desiccant to closed boxes
Especially for paper items and anything with a battery. -
Check batteries every few years
Replacement is routine maintenance; leakage is what ruins a board.
- Blowing into a cartridge — moisture accelerates contact corrosion.
- Water, glass cleaner or abrasives on labels or plastics.
- Long-term storage in a loft, garage or against an exterior wall.
- Leaving a suspect battery inside a rare cartridge indefinitely.

Storing Japanese retro games — FAQ
Do Japanese cartridges still work after 30 years?
Usually yes — mask ROM is durable. What fails first is the save battery in cartridges with battery-backed saves, and oxidised edge connectors. Both are ordinary maintenance items, not a sign of a bad cartridge.
How do I clean cartridge contacts?
Isopropyl alcohol (99%) on a cotton swab, on the metal contacts only, then let it dry fully before inserting. Never use water, and never touch labels or plastic with solvent.
What about discs and manuals?
Store discs upright in their cases, never stacked bare. Japanese manuals and spine cards are thin paper and are the first thing to yellow or curl — keep them dry, flat and out of light.
Do you sell storage cases or protectors for boxed games?
No. If you want a specific Japanese-market protector or case, send a free Sourcing Request and we will look for it in Japan.
