Where to Find Game ID on a Nintendo DS Game Cartridge, Box & Manual

The Game ID (or Game Code) is an 8–10 character alphanumeric string identifying the specific release.

Locations

1. Cartridge label (front): Bottom or side; format: NTR-XXXX-USA or TWL-XXXX-USA
   • NTR = DS original; TWL = DSi-enhanced.
   • XXXX = 4-char game code (e.g., AMSE = Mario Kart DS).
   • USA/EUR/JPN = region.
2. Cartridge back (PCB): Small sticker near contacts; same code.
3. Box spine/side: Same code; often with ESRB/PEGI rating.
4. Manual (last page): Sometimes printed with copyright info.

Examples

• Mario Kart DS: NTR-AMSE-USA
• Pokémon Diamond: NTR-ADAP-USA
• New Super Mario Bros.: NTR-ANMP-USA
• Zelda: Phantom Hourglass: NTR-AZLP-USA
