Note: Game Boy Advance games were discontinued in 2010 and are now retro collectibles. No live store inventory exists, so use these Trinidad channels:
| Real Cartridge | Fake Cartridge |
|---|---|
| Nintendo logo on PCB | No logo / "GAME" / Chinese text |
| Battery (CR1616) for save data | No battery / soldered blob |
| Label: glossy, embossed numbers | Matte, blurry, misaligned |
| Screw: Tri-wing (official) or Phillips | Often Phillips only |
| Save works reliably | Corrupts, "Save error" often |
