Update Games On CFW Switch: A Comprehensive Guide
Keeping your games up-to-date on a CFW (Custom Firmware) Nintendo Switch is crucial for accessing new content, bug fixes, and improved performance. However, the process can be a bit tricky compared to a stock Switch due to the modifications made to the system. This guide provides a comprehensive, user-friendly walkthrough on how to update your games on a CFW Switch, ensuring you can enjoy the latest features without bricking your console.
Understanding the Basics
Before we dive into the how-to, it's essential to understand some key concepts. When you're running CFW, you're essentially bypassing the official Nintendo update channels. This means you can't just go to the eShop and download updates like you normally would. Instead, you'll need to use alternative methods, which often involve downloading update files from other sources and installing them manually. This might sound daunting, but don't worry, we'll break it down into manageable steps. Remember, safety first! Always download your update files from trusted sources to avoid malware or corrupted data that could harm your Switch. Also, make sure your CFW is up-to-date to maintain compatibility with the latest games and updates. Keeping your CFW current ensures a smooth and stable gaming experience. This involves not only the CFW itself, but also the associated payloads and homebrew applications. It's a good practice to check for updates to your CFW regularly and follow the instructions provided by the CFW developers to update it correctly. Finally, backing up your system before making any changes is always a good idea. This way, if something goes wrong, you can restore your Switch to its previous state and avoid any permanent damage. Creating a NAND backup can be a lifesaver, so make sure you have a reliable method for doing so.
Prerequisites
Before we get started, there are a few things you'll need to have in place:
- A CFW Switch: Obviously, this guide is for those who already have a Nintendo Switch with Custom Firmware installed.
 - An SD Card: Make sure you have enough free space on your SD card to accommodate the game updates. A larger SD card is generally recommended for CFW users.
 - A Method for Transferring Files: You'll need a way to transfer files to your Switch's SD card. This could be through an SD card reader connected to your computer or via FTP (File Transfer Protocol) if your CFW supports it.
 - Game Update Files: You'll need to obtain the update files for the games you want to update. These files usually come in the form of 
.nspor.xcifiles. Be very careful where you download these files from, as downloading from untrusted sources can pose a security risk. Always verify the integrity of the files you download by checking their checksums. - A Homebrew App for Installing Updates: We recommend using Tinfoil or Awoo Installer. These are popular homebrew applications that make installing game updates much easier.
 
Step-by-Step Guide to Updating Games
Now, let's get to the actual process of updating your games. We'll be using Tinfoil as an example, but the steps should be similar for other installers.
Step 1: Download the Game Update Files
The first step is to find and download the update files for the games you want to update. As mentioned earlier, be extremely cautious about where you download these files from. Stick to trusted sources and always verify the integrity of the files. Once you've downloaded the files, make sure they are in .nsp or .xci format. These files contain the updated content for your games and are essential for the update process. Remember to organize your downloaded files in a way that makes them easy to find and manage on your SD card. Creating separate folders for different games or update types can help you keep things organized and prevent confusion later on.
Step 2: Transfer the Update Files to Your SD Card
Next, you'll need to transfer the update files to your Switch's SD card. You can do this by connecting your SD card to your computer using an SD card reader or by using FTP if your CFW supports it. Create a folder on your SD card specifically for game updates to keep things organized. Once you've transferred the files, double-check to make sure they are in the correct location and that the transfer was successful. A corrupted or incomplete file can cause problems during the installation process, so it's always best to be thorough. If you're using FTP, make sure your Switch and computer are on the same network and that you have the correct FTP settings configured. This will ensure a smooth and reliable file transfer.
Step 3: Launch Tinfoil (or Your Preferred Installer)
Now, power on your Switch and launch Tinfoil (or your preferred installer) from the Homebrew Menu. If you don't have Tinfoil installed, you'll need to download it and place it in the switch folder on your SD card. Once Tinfoil is launched, it will scan your SD card for installable files. This process may take a few minutes, depending on the size of your SD card and the number of files you have on it. Make sure your Switch is connected to the internet if you plan to use Tinfoil's online features, such as downloading games or updates directly. However, for the purpose of this guide, we'll focus on installing updates from files on your SD card. If you encounter any errors during the launch of Tinfoil, make sure your CFW is up-to-date and that you have the latest version of Tinfoil installed. Outdated software can often cause compatibility issues and prevent applications from running correctly.
Step 4: Navigate to the Location of Your Update Files
Using Tinfoil's file browser, navigate to the folder where you placed the update files on your SD card. Tinfoil should recognize the .nsp or .xci files as installable updates. Take your time to browse through the file system and locate the correct folder. If you have a lot of files on your SD card, you can use Tinfoil's search function to quickly find the update files. Once you've found the files, make sure they are the correct updates for the games you want to update. Installing the wrong update can cause compatibility issues or even corrupt your game data, so it's important to be careful. If you're unsure about which update file to install, you can check the file name or consult a trusted online source to verify its authenticity and compatibility.
Step 5: Install the Update Files
Select the update file you want to install and press the install button. Tinfoil will begin the installation process, which may take a few minutes depending on the size of the update. During the installation, Tinfoil will display a progress bar indicating the status of the installation. It's important to be patient and not interrupt the installation process, as this can cause errors or even brick your console. Once the installation is complete, Tinfoil will display a confirmation message. You can then repeat this process for any other games you want to update. If you encounter any errors during the installation, check the error message for clues about what went wrong. Common causes of errors include corrupted files, insufficient storage space, or compatibility issues. If you're unable to resolve the error yourself, you can consult online forums or communities for assistance.
Step 6: Verify the Update
After the installation is complete, it's a good idea to verify that the update was installed correctly. Launch the game you just updated and check the version number or look for any new features or content that were included in the update. This will confirm that the update was successfully installed and that your game is now running the latest version. If you encounter any problems or issues after installing the update, such as crashes or glitches, you can try reinstalling the update or consulting online forums for assistance. In some cases, it may be necessary to revert to a previous version of the game if the update is causing too many problems. However, this should be a last resort, as it may prevent you from accessing certain features or content.
Troubleshooting Common Issues
Even with careful preparation, you might run into some issues during the update process. Here are a few common problems and their solutions:
- Installation Errors: If you encounter an error during installation, make sure the update file isn't corrupted and that you have enough free space on your SD card. Also, ensure that your CFW is compatible with the update.
 - Game Not Launching: If the game fails to launch after the update, try reinstalling the update or checking if there are any compatibility issues with your CFW.
 - Crashing: If the game crashes after the update, it could be due to a bug in the update itself. Check online forums to see if other users are experiencing the same issue and if there are any known fixes.
 - Slow Download Speeds: If you're downloading updates directly through Tinfoil, slow download speeds can be frustrating. Try switching to a different source or using a download manager to improve speeds.
 
Staying Safe
Updating games on a CFW Switch requires a degree of caution. Here are some tips to stay safe:
- Only Download from Trusted Sources: Always download update files from reputable sources to avoid malware or corrupted files.
 - Verify File Integrity: Check the checksum of the downloaded files to ensure they haven't been tampered with.
 - Keep Your CFW Updated: Regularly update your CFW to maintain compatibility with the latest games and updates.
 - Backup Your System: Before making any changes, create a NAND backup of your Switch. This will allow you to restore your system if something goes wrong.
 
Conclusion
Updating games on a CFW Switch might seem complicated at first, but with the right tools and knowledge, it's a manageable process. By following this guide, you can keep your games up-to-date and enjoy all the latest features without compromising the stability of your CFW. Remember to always prioritize safety and download files from trusted sources. Happy gaming, guys!
