Before you buy

What to look for

• Loose cartridge: a lower-cost way to collect; ask for clear front, back, and connector photos, plus a working/test or return policy.
• Complete in box: verify box, manual, and inserts are actually included and match the game’s version and region; check condition in separate photos.
• Sealed: request clear photos of all sides and the wrap. Shrink wrap by itself is not proof of a factory seal.
• Authenticity clues: compare label color and print, spelling, the stamped two-digit label code, Nintendo / “Made in Japan” back markings, and the correct 3.8 mm Game Boy screw. These are clues, not proof; an opened-cart board should be compared with a known-good copy of the same game and region.

Visual signs are not definitive authentication. Ask for specific photos and compare against trusted references; for uncertain or high-value carts, consider an in-person board inspection.
