1. Check Code Validity and Compatibility:
* Ensure the code is correct and specifically designed for Pokemon FireRed. There are separate codes for different games.
* Verify the code's purpose. Some codes might be for specific encounter locations (like a trainer battle) rather than choosing a starter.
* Look for updated codes. Older codes might not function correctly with newer firmware or patched games.
2. Use Alternative Codes:
* Find codes specifically designed for shiny starters. There might be codes that directly manipulate the shiny flag for the starter Pokemon.
* Consider using a code that gives you a specific shiny Pokemon. You can find codes that directly give you a specific Pokemon in its shiny form, bypassing the starter selection process altogether.
3. Try Code Variation:
* Experiment with slightly different versions of the same code. Some codes have variations that might work better with your specific game setup.
* Try removing specific parts of the code. If a particular portion seems to be causing the problem, try removing it and see if that resolves the issue.
4. Consider Other Methods:
* Use a Shiny Pokemon Finder tool. Some programs allow you to search for shiny Pokemon by manipulating the game's save file.
* Manually breed for a Shiny. While time-consuming, breeding Pokemon for a Shiny is a legitimate way to obtain them.
Important Notes:
* Using Action Replay codes can potentially affect your save file and lead to game instability. Make sure to back up your save file before using any codes.
* Some codes might be considered cheating. It's important to use them responsibly and ethically.
If you're still struggling after trying these solutions, it's likely the Action Replay code itself is faulty. You'll need to search for a new code or a different method to obtain a shiny starter.
