If you're looking to modify the game or unlock content, you'd need to use external tools like:
* Action Replay or similar cheat devices: These can be used to modify game data, but they often require some technical knowledge.
* ROM hacking: This involves modifying the game's code directly, which is a more advanced technique and can potentially damage your game file.
It's important to note that:
* Using cheat devices or ROM hacking may void your game's warranty and potentially cause damage to your game save file.
* Most cheat devices and ROM hacking techniques are not officially supported by the game developers.
If you're looking for a way to experience the game differently, it's best to stick to the intended gameplay mechanics and explore the game's many challenges and secrets.
