Pokémon Conquest is a beloved Nintendo DS crossover that combines the classic world of Pokémon with the strategic mechanics of Nobunaga’s Ambition. While it garnered praise for its engaging gameplay and unique concept, some users have run into a frustrating problem: not being able to delete their save data. Whether you’re trying to start fresh or fix a corrupted file, not having control over your game data can be incredibly annoying. If you’re facing the issue of the “delete save not working” in Pokémon Conquest, this comprehensive guide will help you understand the common causes and walk you through effective fixes.
Understanding the Save System in Pokémon Conquest
Before diving into fixes, it helps to understand how Pokémon Conquest handles saved data. This game, like many others on the Nintendo DS platform, stores its game data directly on the cartridge. This means that the save file is tied to the physical game card, and deleting or resetting it requires that you use specific button combinations or access hidden settings within the game menu.
The game only allows a single save slot, unlike mainline Pokémon games that often offer more flexibility in data management. Because of this limitation, and potential quirks with older hardware, deleting the save file isn’t always as simple as it should be.

Common Symptoms When Deleting Save Doesn’t Work
Gamers trying to delete their save in Pokémon Conquest often report some of the following issues:
- Save data persists even after attempting to reset through standard button combinations.
- The game automatically loads into the existing save without presenting deletion options.
- Button presses to delete data don’t register or don’t function as expected.
- The game crashes after attempting to delete the save file.
If you’re experiencing any of these symptoms, rest assured that you’re not alone—and there are steps you can take to address the issue.
How to Properly Delete Save Data in Pokémon Conquest
First, let’s make sure that you’re using the correct method to attempt a save file deletion. Unlike simpler menus found in newer games, Pokémon Conquest requires that players hold a specific button combination on the title screen to delete save data.
Step-by-Step Method
- Insert your Pokémon Conquest cartridge into your DS or 3DS console.
- Boot up the game and wait until the title screen appears. Important: This must be the screen that displays the game’s logo and copyright text.
- At the title screen, press and hold the following buttons simultaneously: Up + Select + B.
- A prompt should appear asking if you want to delete your save file. Confirm the deletion if you want to proceed.
This is the only in-game method available to delete saved data. If this doesn’t work, proceed with the troubleshooting steps below.
Fixes When the Save Delete Command Doesn’t Work
If you’ve followed the instructions but the deletion still fails, the problem might be deeper than just a missed button combo. Here’s what you can do:
1. Ensure Button Inputs are Registered
Older DS and 3DS units often experience wear-and-tear that affects button responsiveness. If one or more buttons in the required combination (Up, Select, B) aren’t registering properly, the game will not acknowledge the command.
- Test button functionality in other games or system menus.
- Try using a different DS/3DS console if available.
2. Perform a Full System Restart
Restart your system and try the reset sequence again. Sometimes, loading the game after a fresh reboot can resolve temporary memory or input issues.
3. Clean the Cartridge
Dirty or corroded cartridge contacts can interfere with game performance. To clean your cartridge:
- Use a microfiber cloth or cotton swab with a small amount of isopropyl alcohol.
- Gently clean the gold contacts on the bottom of the cartridge.
- Allow the contacts to dry fully before reinserting into your DS/3DS.
4. Update or Reset DS/3DS Firmware
While less common, occasionally a glitch at the firmware level can interfere with games loading or responding properly. Ensure your DS/3DS is running the latest firmware. You can also try restoring factory settings—but back up any data first, as this wipes the system.
5. Save File Corruption
If the save file is corrupted, the game may resist both loading and deletion.
- Try booting into the game multiple times; sometimes the save can be recovered temporarily.
- If you get into the game, try creating a new save over the existing one (if allowed).
- If corruption persists, deletion using the physical button method may eventually succeed after several attempts.

Alternatives When All Else Fails
If you’ve exhausted all in-console methods and the save file still won’t delete, there are a few alternative approaches—though they come with risks.
1. Use a Save Data Editor or Third-Party Tool
There are several tools for managing DS save data, such as:
- Action Replay DS
- R4 Flashcarts with save conversion features
- PC-based save managers like DeSmuME
⚠️ Important Note: These solutions should be used responsibly. Altering game data can render your cartridge unusable if you make a mistake. Only attempt this if you’re comfortable with technical tools and fully understand the processes involved.
2. Replace the Cartridge (Last Resort)
If your save file is corrupted beyond repair and no method works, it could indicate hardware failure with the cartridge itself. In that case, replacing the cartridge with a new or refurbished one may be your only option.
Preventing Future Issues
To avoid a repeat of save-related frustrations in the future, consider the following best practices:
- Save regularly: While this won’t prevent deletion errors, it keeps data updated in case of unexpected shutdowns.
- Avoid rapid powering on/off: Let the game save and shut down naturally to prevent file corruption.
- Store cartridges properly: Keep your game free from dust and moisture, which can affect long-term performance.
- Use emulators with care: While not officially endorsed, emulating Pokémon Conquest allows the use of multiple save states—making file corruption far less damaging.
Conclusion
Encountering issues with deleting your save in Pokémon Conquest can be extremely frustrating, but most cases are solvable through the correct reset command and attention to your hardware condition. Whether it’s unresponsive buttons or a corrupted save file, there’s almost always a workaround. For players who are truly stuck, alternative hardware or even emulation might become necessary avenues.
The good news is that this unique Nintendo DS title remains a fan-favorite, and once you’re able to reset your game and start fresh, you can rediscover its deep strategy and unique gameplay unburdened by past save files.
If you’ve tried all steps above and deletion still doesn’t work, you may want to consult technician services or consider archiving your gameplay digitally to preserve personal progress in a more flexible format.
