The game's developers did not include any built-in cheat functionality. This means there is no way to access hidden menus or codes to unlock characters, items, or other gameplay features.
However, there are a couple of things to consider:
* Game Genie/Action Replay: Some third-party devices, like Game Genie or Action Replay, might have codes that can be used to unlock cheats in certain games. However, finding reliable codes for Lego Batman DS can be difficult and may not work as intended.
* Modding: There might be community-made mods or hacks available for the game. However, these are generally not officially supported and can potentially damage your game cartridge or console.
Remember, using unofficial methods to access cheats can be risky and may void your game's warranty.
Instead of searching for cheats, you can focus on enjoying the game's regular gameplay and achieving unlockables through natural progression. The game offers plenty of challenges and rewards that can be enjoyed without the need for cheat codes.
