Let’s get this out of the way first:
| Problem | Likely Solution | | :--- | :--- | | "My DS camera won’t scan the QR code" | That’s correct. The DS camera cannot read modern QR codes. You must use the method. | | "The ghost data crashes my game" | You used a QR code for a different region (e.g., European save on a US ROM). Ensure the Game ID matches: AMCE (US), AMCP (EU), AMCJ (JP). | | "The QR code is just a jumbled mess" | You tried to scan a visual barcode from 2005. Those are obsolete. Look for black-and-white square QR codes generated by modern tools. | | "MelonDS doesn't have a QR scanner" | Correct. MelonDS does not have a built-in camera feature. You must manually copy the hex from an external scanner. | mario kart ds qr code
