Spotting repro carts

Reproduction cartridges are everywhere, and the good ones fool people at genuine-cart prices. Five checks catch most of them.

1. The label

Originals were offset-printed: crisp text, correct colours, and on many platforms a subtle texture or gloss that repros miss. Fakes are usually inkjet or laser prints — look for pixelated edges on small text, oversaturated colour, glossy sticker stock, and labels that sit slightly wrong in the cart's recess. Compare against photos of a known-genuine copy; label variations are documented for most valuable titles.

2. The shell and screws

Nintendo shells use security screws and precise plastic with era-correct mould marks; many repros use Phillips screws, shinier or lighter plastic, or shells with no embossed logos. A "Nintendo" shell with a game that never shipped in that shell style is a giveaway.

3. The board

The definitive check. Open the cart (collectors do; sellers who refuse board photos are telling you something). Original boards carry the platform-holder's silkscreen (e.g. Nintendo part numbers), date codes, and mask-ROM chips. Repros show generic green PCBs, flash chips with modern date codes, glob-top blobs, or hand-soldered EPROMs. One board photo settles it.

4. Weight and connector

Repros often weigh noticeably less. The edge connector on originals shows even, factory gold plating; repros can have thin, coppery or freshly-shiny contacts.

5. The price and the seller

A $600 game listed at $80 "no box, works great" from a seller with 12 feedback is not your lucky day. Check the seller's history for multiples of the same rare title — repro mills list the same grail again and again. Established sellers, real photos of the actual item, and board shots on request are the baseline for any expensive cart.

Repros aren't evil — mislabelled ones are

An honest repro (sold as a repro, at repro money) is a fine way to play an unaffordable game. The problem is repros sold as genuine. When in doubt on anything valuable: board photo, or walk away.
