Entering Codes on Nintendo DSi: Warning Against Unauthorized Tools – Only Specific Contexts

DSi Has No General "Code Input" Menu

The DSi only accepts codes in specific contexts:

• Nintendo Points / eShop Codes: Shop → Add Points → Enter 16-digit code.
• Game-Specific Cheats: Some titles (e.g., Pokémon Mystery Gift) have in-game “Receive Gift” → “Via Code.”
• Action Replay / Flashcart Menus: Homebrew only – not official.

Risks of Unauthorized Code Tools

• System instability / brick.
• Nintendo Network ban (DSi Shop closed 2017, but 3DS NNID linked).
• Save corruption.

Safe Alternatives

• Official game guides for legitimate unlockables.
• Homebrew (TWiLight Menu++, hiyaCFW) for cheat databases (.cht) – at own risk, offline only.

Play fair; the DSi library is best enjoyed as designed.
