How to Spot a Fake Retro Game Cartridge (Reproduction Guide)

Reproduction cartridges ("repros") are copies made to look like the real thing. Some are sold honestly as repros. Plenty are not. The more a game is worth, the more fakes there are, and the popular role-playing games and handheld titles get hit the hardest.

No single check proves a cart is real. Fakes get better every year. But stack these checks together and most fakes fall apart fast.

1. Start with the deal itself

If the price is far under what the game actually sells for, slow down. Same if one seller has five copies of a rare game, all in perfect shape. Real collections are messy. Fakes are usually brand new and identical.

2. Look hard at the label

Compare it side by side with photos of a known authentic copy. Repro labels often give themselves away with blurry or pixelated print, colors that are too bright or too washed out, the wrong finish (glossy where the original is matte), a label that sits crooked or is the wrong size, or edges that are already peeling on a game that looks new otherwise.

3. Check the shell and the screw

The plastic on a fake is often a shade off in color, feels lighter or rougher, or has seams that don't line up.

Most original Nintendo cartridges were closed with a special security screw, and the exact type depends on the system. A plain Phillips screw is a warning sign. It is not proof on its own, because owners sometimes replace screws, but it means you should look inside.

4. Look at the board inside

This is the strongest check. With the right screwdriver bit, open the cart and look at the circuit board. Authentic boards are marked with the manufacturer's name, a part number, and chips with printed labels.

Common repro tells: chips with no markings, a blob of black epoxy where a labeled chip should be, a board that looks too clean and cheap, or a board that doesn't match photos of a known authentic board for that exact game. Board designs vary by game and by print run, so always compare against the same title.

5. Test the save

Fakes often save badly, lose their save, or can't save at all. Play long enough to save, power off, and load it back up.

One thing that is not a red flag: on some older genuine games, a message that the internal battery has run dry. Batteries in old carts die with age. A dead battery can be replaced. It actually points toward an old, original cart.

6. When in doubt, ask

Send us clear photos of the front, the back, and the board if you can open it. We'll tell you what we see, straight. Every game we sell is tested, photographed for real, and if anything is a reproduction, we say so on the listing.
