How to Identify Real vs. Fake Japanese Game Cartridges

Why Fake Cartridges Are a Problem

The popularity of retro games has unfortunately led to a wave of fake or reproduction cartridges, especially for Japanese titles. These fakes are often sold online without disclosure, putting collectors and gamers at risk of wasting money on worthless copies.

How to Identify a Real Japanese Cartridge

Here are some of the most reliable signs to spot authentic cartridges:

 
• Label printing: Originals have sharp, vibrant prints. Fakes may appear washed out or pixelated.
 
• Screw type: Real cartridges use proprietary security screws. Fakes often use Phillips screws or glue.
 
• Weight and feel: Original cartridges have consistent plastic molds. Fakes may feel too light or too rough.
 
• PCB inspection: If possible, open the cartridge. Authentic games use Nintendo or Sega-marked boards.
