1. Delete your Save Data:
* This is the most drastic option and will completely erase your progress.
* To do this, go to the "System Settings" menu on your Nintendo DS.
* Select "Data Management" and then "Nintendo DS Data."
* Find the "Pokemon Conquest" save data and delete it.
2. Start a New Campaign:
* While you can't delete individual save files, you can choose to start a new campaign.
* This will allow you to play the game from the beginning, but will not erase your progress on any other campaign you have already started.
3. Use the "New Game+" Option:
* Once you have completed the main story, you unlock the "New Game+" option. This allows you to start a new game with all your existing Pokémon and items, but with some adjustments to the game's difficulty.
Important Note: There is no "restart" option within the game itself. You will need to use one of the methods above to effectively reset your progress.
It's always a good idea to back up your save data before making any major changes to your progress. You can do this by transferring your save data to a SD card or using a backup utility.
