Help:Dumping games

In order to get a copy of the content files and executable, you will need to dump Breath of the Wild from a console. This article provides instructions for Wii U and Switch users.

Wii U

The easiest method for dumping BOTW in a manner compatible with tools like Cemu and BCML is to use Dumpling.

Prerequisites

  • BOTW 1.5.0 on your Wii U
  • Any Wii U (Method 1)
  • Modded Wii U with Homebrew Launcher (Method 2)

Dumping your game files

Method 1 (Any Wii U) - Website

  1. Insert an SD card into your Wii U.
  2. Insert any USB devices or game discs you’d like to use in the dump process.
  3. Launch the Internet Browser app.
  4. Go to https://dumplingapp.com/
  5. Select "Dump digital games" or "Dump a game disc" as appropriate.
  6. Select BOTW using the (A) button and then press (START) (selection N/A if using a disc). Make sure to check the boxes for base game, update, and (if applicable) DLC.
  7. Set the dump destination.
  8. Select (START) to begin dumping (which can take a very long time).
  9. Once finished, you can put the SD card into your PC and copy the files onto your hard drive.

Method 2 (Modded Wii U only) - Homebrew App

  1. Download the latest release of Dumpling from here.
  2. Extract the ZIP to the root of your SD card.
  3. Before running Dumpling, disable auto power off and standby on your Wii U.
  4. Insert any USB devices or game discs you’d like to use in the dump process.
  5. Open Dumpling from the Homebrew Launcher.
  6. Select "Dump digital games" or "Dump a game disc" as appropriate.
  7. Select BOTW using the (A) button and then press (START) (selection N/A if using a disc). Make sure to check the boxes for base game, update, and (if applicable) DLC.
  8. Set the dump destination.
  9. Select (START) to begin dumping (which can take a very long time).
  10. Once finished, you can put the SD card into your PC and copy the files onto your hard drive.

Switch

Dump the game files directly to your SD card using nxdumptool. Update data can only be processed if the base game is available, because they share the same filesystem. DLCs don't, so they have to be dumped separately.

Warning: If you misbehave (piracy, online cheating or anything equally stupid), you might get banned from Nintendo online services. If you do not want to leave any traces, turn on airplane mode, back up your eMMC before running any homebrew and do not ever go online before you have restored the backup.

Prerequisites

  • nxdumptool.
  • Keys file generated using Lockpick_RCM, located at sdmc:/switch/prod.keys. Run the payload on your console through RCM in order to dump the keys needed by nxdumptool to decrypt contents.

Dumping game files

  • On your Switch, open nxdumptool. Afterwards:
    1. If you have the gamecard: Select Dump gamecard content.
    2. If you have the eShop version: Select Dump SD card / eMMC content, then select BotW.
  • Select RomFS options.
  • Highlight the Use update/DLC option and use the left/right buttons to cycle through the available updates/DLCs for the game.
    1. If you have no available updates/DLCs, this option won't appear. You'll only be able to dump the files from the non-updated base game (which is the same to just leaving this option set to No).
    2. Updates are tagged as (UPD), and they use 01007EF00011E800 as their ID. v786432 (0.0.12.0) corresponds to BotW v1.6.0 update.
    3. DLCs are tagged as (DLC). 01007EF00011F001 and 01007EF00011F002 are the known IDs for the existent BotW DLCs.
  • Select RomFS section data dump and wait for the process to finish. This will dump the internal filesystem from the selected update/DLC to the inserted SD card.

Just like it was previously mentioned, updates share their filesystem data with the base game, so dumping the RomFS from an update is equivalent to dumping the whole filesystem from the updated game data. In other words, it isn't necessary to dump the base game filesystem separately if you choose an update.

DLCs, on the other hand, must be dumped separately.

When you're done, you'll be able to find the output dumps in sdmc:/switch/nxdumptool/RomFS.

It is recommended to copy these dumps to your PC, for use with modding tools and to free up space on your SD card.

Dumping binaries (executable files)

Executables in Switch titles are stored in a different section known as the ExeFS, which is only available in base games and updates. Unlike RomFS data, ExeFS data isn't shared between the update and its base game.

These files can also be dumped using nxdumptool.

  • On your Switch, open nxdumptool. Afterwards:
    1. If you have the gamecard: Select Dump gamecard content.
    2. If you have the eShop version: Select Dump SD card / eMMC content, then select BotW.
  • Select ExeFS options.
  • Highlight the Use update option and use the left/right buttons to cycle through the available updates for the game.
    1. If you have no available updates, this option won't appear. You'll only be able to dump the binaries from the non-updated base game (which is the same to just leaving this option set to No).
    2. Updates use 01007EF00011E800 as their ID. v786432 corresponds to BotW v1.6.0 update.
  • Select ExeFS section data dump and wait for the process to finish. This will dump the binaries from the selected update to the inserted SD card.

When you're done, you'll be able to find the output dump in sdmc:/switch/nxdumptool/ExeFS.
