Game Boy Advance games have been counterfeited for a long time, and I run into fakes regularly. Customers have told me they bought the game years ago in China, but I've also had people swear they bought it brand new from Walmart or GameStop. That tells you how deep this goes. Most major retailers simply don't have the means to spot these before they hit the shelf, which means fakes have been in the market for years.
Quick Authentication Checklist
- Tip 1: Look for imprinted numbers on the front label.
- Tip 2: Look at the Nintendo Seal of Quality. Real cartridges have a clear, sharp seal.
- Tip 3: Open the cartridge and check the game board for the right parts and markings.
- Tip 4: Check the font and markings on the cartridge board for anything that looks off.
- Tip 5: Examine the cartridge shell for the manufacturer’s molding stamps.
- Tip 6: Know the right shell colors for each game and watch for any that look odd.

Step 1: Label Inspection
- Real cartridges have imprinted numbers “stamped into” the front label, generally two characters like 11, 03, or 0B. Fakes usually don’t have these numbers, or they appear very faint or missing entirely.
- A real cartridge has a clear Nintendo Seal, easy-to-see imprinted numbers, and a crisp, sharp font on the label. If the font appears blurry, uneven, or inconsistent with known authentic labels, it’s likely a fake.

Step 2: Cartridge Board Inspection
- Checking the cartridge’s internal circuit board and chips is a reliable way to see if a GBA game is real.
- Look for a chip labeled “MX” on the circuit board. Authentic cartridges have this chip, and counterfeiters often miss it. Many fakes use different chips or do not have the MX marking at all.
- Compare the design and size of the “Nintendo” font printed on the circuit board to a real one.

2A. The 'Battery' Test
- A real Pokémon Emerald board has an internal battery. Many fakes have a black circular blob of epoxy instead, which is a clear sign the game is not real.
- You need a Y-shaped screwdriver to open GBA games for inspection.
- This works great for Pokémon Emerald, Sapphire & Ruby versions as they all should have a CR1616-sized battery.
- Pokémon Leaf-Green and Fire-Red versions do not have a battery, so you can skip this step.
Step 3: Analyzing the Cartridge Shell
- Check if the cartridge shell is the right color. Real Pokémon Emerald shells are light green. If the color looks different, it might be a fake.
- Real cartridges have “Nintendo” stamped on the back shell. Make sure to check the spelling on both the back and front.
- Many fakes have spelling mistakes, which is a clear sign the cartridge is not genuine.
3A. Look At the Back Shell for Impressions
- Genuine Nintendo shells have two square mold impressions inside the back shell. Fakes usually do not have these.
- Look inside the shell for these molding stamps or markings to confirm it is real.

3B. Look At the Front Cartridge Shell
- Real GBA shells have an imprinted rectangle right behind the label area.
- Fake cartridges often use shells where you can see the label through the plastic.

Step 4: Check the Cartridge Color
Which Color Should Your Cartridge Be?

NTSC Pokémon cartridges have specific shell colors that help you tell if they’re real:
- Pokémon Leaf Green and Pokémon Emerald: green shell
- Pokémon Sapphire: blue shell
- Pokémon Ruby and Pokémon Fire Red: red-toned shells
- Pokémon Mystery Dungeon and Pokémon Pinball: gray shells

Just like with every other counterfeit article I've written, the easiest way to verify a game is to open it. A photo of the board tells you more than anything on the outside ever will.
