JDM retro game finder
Type a game you want. Get its Japanese title, the cartridge code to hunt for on the shelf, and links to buy it.
Point at the JAN barcode on the back of a disc case — PS1–PS3, PSP, Saturn, Dreamcast, DS. The store's own price sticker won't work; use the printed one. Bare cartridges have no barcode — type the product code in the search box instead.
