Here's why you might be getting a "bad egg" in Diamond after using a "win all contest" code:
* Code Incompatibility: The code you found might be designed for a different version of the game, or even a different game entirely. Game versions and even different consoles (like the original DS and the DSi) can have different internal code structures.
* Game Glitches: Action replay codes can interfere with the game's internal logic, leading to unintended results like glitches. Sometimes, the "bad egg" might be a side effect of forcing the game to always win contests.
* Corrupted Save Data: If the code messes with the game's save files, it might corrupt your data, resulting in unexpected outcomes like bad eggs.
Here's what you can try:
1. Double-check the Code: Make sure you've entered the code correctly. Check the source of the code to ensure it's accurate and intended for your specific game version.
2. Try a Different Code: There might be other "win all contest" codes available online. Look for ones specifically for your game version and console.
3. Start a New Game: If you suspect your save data is corrupted, starting a new game might be the best option.
4. Back up Your Save Data: Before using any action replay codes, it's always a good idea to back up your save data. This way, if something goes wrong, you can always restore your game.
Important: Use action replay codes at your own risk. Always backup your save data and proceed with caution.
