Buying Japanese Retro Games — A Practical Guide
Six things worth checking before you buy any original Japanese game — cartridge, disc, or floppy. Plain answers from someone who handles these copies every day.
Six things to check
Most problems with used retro games fall into the same handful of categories — no matter the platform. Work through these six points and the common pitfalls are covered.
-
Choose a seller who tests it before shipping
A copy that has actually been powered on and checked is a known quantity. An untested one is a gamble you only settle after it arrives.
Look for a seller who states what was tested — not just "working," but whether the game loaded, whether saves held, and whether the copy was cleaned. A serious seller can answer those questions directly.
-
Confirm it works with your console
Japan's retro games were made for Japanese hardware. Region connectors, voltage, and lockout chips differ from North American and European machines.
Cartridges: check the pin count matches (Famicom = 60-pin, NES = 72-pin; they will not fit without an adapter). Discs: PlayStation, Saturn, and Dreamcast are region-locked. Game Boy and Game Boy Color are region-free — you can play Japanese carts on any system.
-
If the game saves your progress, check the battery
Cartridge-based saves run off a small coin-cell battery. Most are now 30+ years old — a dead one wipes your progress without warning.
Ask whether the save function was confirmed working. Disc-based games (PlayStation, Saturn, Dreamcast, GameCube) save to an external memory card instead — no battery to worry about.
-
Check the physical condition of the media
Dirty contacts are the most common cause of startup trouble in cartridges. On discs, deep scratches cause read errors and freezes.
Cartridges: look for a seller who cleaned the contacts before shipping. Discs: ask for a photo of the underside — light surface marks are fine; deep radial scratches are not. Famicom Disk System: the magnetic disk itself can wear, and the plastic shell can crack.
-
Verify it is genuine, not a reproduction
Sought-after titles — especially rare Famicom, Super Famicom, and PC Engine games — are targets for reproduction boards with replacement labels.
Ask for a photo of the circuit board. Authentic boards have factory markings and the publisher's name etched on the PCB. Favour a shop holding a Japanese second-hand dealer licence (古物商) — their stock is legally traceable, which is your simplest guard against fakes.
-
Read the seller's record and return policy
A 100% positive record across thousands of sales tells you that packing, communication, and problem-solving all work for everyone. A return policy protects you if something is off.
Confirm a clear return window exists before you buy.
Notes by media type
The six universal checks apply everywhere. These additions are specific to the format.
Cartridge-based games
Cartridges are robust — but contacts corrode, and batteries fade. The two things most worth confirming before you buy.
- Famicom 60-pin connector. Battery saves common. Clean contacts before use.
- Super Famicom 46-pin connector; SNES games do not fit without an adapter. Battery saves in most RPGs and strategy titles.
- Game Boy Region-free — plays on any Game Boy system worldwide. Battery saves on longer titles.
- Game Boy Color Region-free. GBC games are backwards compatible with original Game Boy.
- Nintendo 64 N64 is region-locked. Japanese N64 cartridges will not fit a North American console without a physical adapter.
- Mega Drive Region-locked by lockout chip. Japanese Mega Drive carts need a Japanese console or a region converter.
- PC Engine HuCards are region-free; PC Engine CD-ROM² discs require the correct system. Confirm which format the title uses.
Disc-based games
No battery to worry about — saves go to an external memory card. The main concern is disc surface condition and region lock.
- PlayStation Region-locked. No battery in discs — saves go to a separate memory card.
- Sega Saturn Region-locked. Requires 4MB RAM cart for some titles (e.g. Dungeons & Dragons Collection, X-Men vs. Street Fighter).
- Dreamcast Region-locked. GD-ROM format; standard CD drives cannot read them.
- GameCube Region-locked. Uses mini-discs — store upright or in a case, not flat in a pile.
Magnetic disk
- Famicom Disk System Magnetic floppy disk — fragile shell, wear-prone media. The drive belt on the console side fails commonly; an unreliable read is usually the console, not the disk.
