Citra Texture Dumping and Custom Textures Guide 2026

Want to enhance your gaming experience on Citra? With Citra’s texture dumping and custom texture features, you can extract in-game textures and apply high-quality custom texture packs for a more personalized and visually stunning experience. This guide will walk you through everything you need to know, from dumping textures to applying custom packs.

How to Extract Textures in Citra

Extracting textures in Citra is straightforward and allows you to save in-game textures as .png files for editing or modding.

Steps to Dump Textures:

1. Access the Settings: Open Emulation > Configure… in the Citra menu. Navigate to Graphics > Enhancements and enable Dump Textures. Click OK to save changes.
2. Start Playing: Launch your game and play as usual. Citra will automatically save the textures used during gameplay as .png files.
3. Locate Dumped Textures: Right-click your game in the library and select Open Texture Dump Location. This will open the folder where the textures are saved.
4. Template File: Inside the dump folder, you’ll find a pack.json template file. Copy this file to the load folder for proper configuration when creating custom texture packs.

How to Apply Custom Textures in Citra

Custom textures can significantly enhance the visual quality of your games. Here’s how to apply them:

Steps to Use Custom Textures:

1. Open the Custom Texture Folder: Right-click your game in the library and select Open Custom Texture Location. This is where you’ll place your custom textures.
2. Add Custom Textures: Place your custom .png, .dds, or .ktx files in the folder. Ensure the filenames match the dumped texture filenames for proper loading.
3. Enable Custom Textures: Go to Emulation > Configure… > Graphics > Enhancements and enable Use Custom Textures. Click OK to save changes.
4. Optional: Preload Textures: For better performance, enable Preload Custom Textures. This loads textures into RAM, reducing stuttering but increasing memory usage.

Understanding Texture Dumping Details

How Textures Are Dumped:

• Textures are saved when accessed from the game’s VRAM and uploaded to host memory.
• Only textures with power-of-two dimensions are dumped, excluding host framebuffers.

Filename Details:

Dumped texture filenames include important information:

• Dimensions: Texture size (e.g., 256x256).
• Hash: Unique identifier for the texture.
• Pixel Format: Format of the texture data.
• Mipmap Level: Indicates the texture’s mipmap level (e.g., mip0).

Example:
tex1_256x256_543624189C94B105_12_mip0.png

Pack Configuration with JSON Files

Citra uses a pack.json file for custom texture metadata. This file includes:

• Pack Name and Author: Identifies the texture pack.
• Hash Format: Specifies the hashing method for texture filenames.
• Options: Includes settings for mipmap generation and texture flipping (unsupported for compressed formats).

Custom Filenames:

You can map arbitrary filenames to textures using hash mappings in the pack.json file. Example:

"textures": {
  "114BFC385ED72F15": "logo.png",
  "22B8C43233F640AE": "sky.png"
}

Adding Custom Normal Maps

Normal maps add depth and detail to textures, enhancing the visual quality of objects.

How to Add Normal Maps:

1. Filename Structure: Use the same base filename as the diffuse texture, with .norm added before the extension.
   • Example:
     • Diffuse Map: texture.png
     • Normal Map: texture.norm.png
2. Limitations: Normal maps only work when fragment lighting is enabled in the scene. If lighting is absent, they won’t display, and an error will appear in the log.

Pro Tips for Texture Dumping and Customization

• Use Preload for Performance: Preloading custom textures into RAM can improve performance, especially for large texture packs.
• Organize Your Files: Keep your custom textures and pack.json file well-organized to avoid loading issues.
• Experiment with Normal Maps: Adding normal maps can make your games look more dynamic and detailed.
• Check Compatibility: Ensure your custom textures match the dumped filenames and dimensions for seamless integration.
