Emulating the Nintendo DS experience on today’s powerful computers can be a nostalgic and enjoyable endeavor. Desmume, a popular DS emulator, offers a plethora of features to enhance your gaming experience. However, occasionally you may encounter issues reading save files from your original DS cartridges or other sources. Fortunately, with a few simple steps, you can resolve this problem and continue your adventures in the world of DS emulation.
Desmume’s save file compatibility is generally excellent, supporting various formats created by different DS games. However, some issues may arise due to factors such as the game version, save file corruption, or emulator settings. To troubleshoot these issues, it is advisable to ensure that you have the latest version of Desmume installed. Additionally, verifying the integrity of your save file by loading it into your original DS console can help identify potential corruption problems.
In most cases, Desmume should automatically detect and read your save files when you load a DS game ROM. If this does not occur, you can manually specify the location of your save file by going to File > Load State in the emulator menu. Navigate to the folder where your save file is stored and select it. Desmume will then load the saved game data, allowing you to resume your progress. With these simple steps, you can ensure that Desmume seamlessly reads your save files, providing an uninterrupted and immersive DS gaming experience.
Locating Your Save File
Finding your save file can be a tricky process, but it’s essential for loading your progress in Desmume. Here’s a detailed guide on how to locate your save file:
Step 1: Determine Your Operating System
The location of your save file depends on your operating system. Here are the general paths for different OS:
| Operating System | Save File Location |
|---|---|
| Windows | %APPDATA%\DeSmuME\Battery Saves |
| macOS | ~/Library/Application Support/DeSmuME/Battery Saves |
| Linux | ~/.local/share/desmume/Battery Saves |
Step 2: Find the Specific Save File
Within the Battery Saves folder, you’ll find individual save files for each game you’ve played in Desmume. The save files are typically named after the game’s title and have a .dsv extension.
Step 3: Identify the Correct File
If you have multiple save files for the same game, you can identify the correct one by checking its file size. The file with the largest size usually represents your most recent save progress.

Choosing “Load State”
The “Load State” option in Desmume allows you to load a previously saved game state. This is useful if you want to resume playing a game from where you left off or if you want to load a cheat state.
To load a state, follow these steps:
1. Click on the “File” menu and select “Load State”.
2. In the file browser that appears, select the state file that you want to load and click “Open”.
3. The state file will be loaded and the game will resume from the point where it was saved.
Desmume supports both savestates and in-game saves. Savestates are created by the emulator itself and can be loaded at any time. In-game saves are created by the game itself and can only be loaded within that game.
The following table summarizes the differences between savestates and in-game saves:
| Feature | Savestate | In-game save |
|---|---|---|
| Created by | Emulator | Game |
| Can be loaded | At any time | Only within the game |
| Advantages | Quick and easy to use, can be used to create multiple saves | More stable, can be used to transfer saves between devices |
| Disadvantages | Can be corrupted if the emulator crashes, can’t be used to transfer saves between devices | Slower to use, can only be used to create one save per game |
Which type of save you use is a matter of personal preference. Savestates are more convenient and versatile, but in-game saves are more stable and reliable.
Selecting your Save File
When it comes to choosing a save file, there are two main options: sav and state. Sav files are created automatically by the game and contain all of the game’s data, including your progress, inventory, and settings. State files, on the other hand, are created manually by the player and contain only a snapshot of the game’s state at a specific point in time. They are often used to save a specific moment in the game or to create multiple save points.
To select a save file, simply click on the “File” menu and then select “Open.” A dialog box will appear that allows you to browse your computer for the save file. Once you have selected a file, click on the “Open” button and Desmume will load the game.
Here are some additional tips for selecting a save file:
Use Sav files for long-term storage.
Sav files contain all of the game’s data, so they are the best option for long-term storage. If you are planning on taking a break from the game or if you want to make sure that your progress is safe, you should save your game using a sav file.
Use State files for quick saves.
State files are much smaller than sav files, so they are faster to load and save. They are also a good option for creating multiple save points. If you want to save your game at a specific point in time, you can create a state file.
Keep your save files organized.
If you are using multiple save files, it is important to keep them organized. You can create folders for different games or for different save points. This will make it easier to find the save file that you are looking for.
Resuming your Game
1. Launch DeSmuMe and click on the “File” menu.
2. Select “Open ROM” and navigate to the location of your game ROM file.
3. Once the ROM file is loaded, click on the “File” menu again and select “Load State”.
4. Select the state file that you want to load.
5. Your game will now resume from the point where it was saved.
6. Troubleshooting
If you are having trouble loading a save state, here are a few things to check:
| Issue | Solution |
|---|---|
| The save state file is not compatible with your ROM file. | Make sure that you are using the correct save state file for the ROM file that you are trying to load. |
| The save state file is corrupt. | Try loading a different save state file. |
| DeSmuMe is not configured correctly. | Check the DeSmuMe settings to make sure that they are correct. |
Loading a Save File in Desmume
To load a save file in Desmume, follow these steps:
- Launch Desmume and open the ROM you want to play.
- Click on the “File” menu and select “Load State.”
- Navigate to the location of the save file and select it.
- Click on “Open” to load the save file.
Troubleshooting Save File Compatibility Issues
Corrupted Save Files
If the save file is corrupted, it may not load properly or may cause the game to crash. Some signs of a corrupted save file include unusual characters or symbols in the save data, the save file being significantly larger than expected, or the save file not being recognized by Desmume.
Incompatible Game Versions
If you are using a save file from a different version of the game, it may not be compatible with your current version. Desmume supports multiple versions of some games, but not all. To check if your save file is compatible, refer to the Desmume website or documentation.
Save File Format
Desmume uses its own save file format, which is different from the save file formats used by other emulators or the Nintendo DS itself. If you are trying to load a save file from another emulator or from the original DS, you will need to convert it to Desmume’s format using a third-party tool.
Region Differences
Some Nintendo DS games have different versions for different regions (e.g., Japan, USA, Europe). If you are using a save file from a different region, it may not be compatible with your version of the game.
Encryption
Some Nintendo DS games use encryption to protect their save files. If you are trying to load a save file from an encrypted game without the appropriate decryption key, it will not be readable.
Anti-Piracy Measures
Some commercial Nintendo DS games have anti-piracy measures that may prevent them from loading save files from pirated copies of the game. If you are unable to load a save file for a commercial game, it is possible that the anti-piracy measures are preventing it.
Using Third-Party Tools to Convert Save Files
There are several third-party tools available that can convert save files from one format to another. These tools can be found online for free or for purchase. Some of the most popular third-party save file converters include:
| Tool | Features |
|---|---|
| 3DSaveTool | Converts save files between 3DS, NDS, and GBA formats |
| nds2sav | Converts save files between NDS and GBA formats |
| sav2nds | Converts save files between GBA and NDS formats |
To use one of these tools, simply download and install it on your computer. Then, open the tool and select the source and destination file formats. Finally, click the “Convert” button to convert the save file.
It is important to note that some third-party save file converters may not be compatible with all save file formats. Therefore, it is important to research the tool you are using to ensure that it supports the formats you need to convert.
Once you have successfully converted the save file, you can load it into Desmume using the “File” -> “Open” menu. Desmume will automatically detect the file format and load the save file into the emulator.
