Dumping your Discs allows you to install a copy of your game to the system NAND/an USB device so you can play it without needing the disc.
?> Dumping and installing games requires a working Homebrew setup, so make sure to finish the main guide on installing CFW first before following this.
?> Installing a game to the system memory (NAND) is not recommended as it's limited to either 8 or 32GB depending on your model, making you run out of space pretty quickly if you want to install multiple games.
?> When installing a game to an USB device, we recommend that you use an HDD and not a flash drive, as those are not optimized for constant reading and writing, therefore making them fail quickly. If your HDD is not externally powered, you will need an Y-cable to connect it to two USB slots on the Wii U.
!> In order to install to an USB device, it has to be formatted by the Wii U. Doing this will erase all contents of it, and prevent it from being used on another system unless you re-format it.
?> If your disc game had DLC or updates installed, you will need to transfer the files over to your USB device. You can do this using the Wii U's data management.
?> If you do not have enough space on your SD Card, you can use an advanced technique to install dumps from an USB device. This is not the easiest thing to do, and has the disadvantage of only being able to install the game onto your system memory (NAND).
- An USB storage device (+a Y-cable if needed) with enough space to fit the game you want to dump.
- The [disc2app](http://www.wiiubru.com/appstore/zips/disc2app.zip) Homebrew app.
- The [MochaFAT32](https://www.wiiubru.com/appstore/zips/mocha_fat32.zip) Homebrew app.
- The 1.4 release of [The Homebrew Launcher](https://github.com/dimok789/homebrew_launcher/releases/tag/1.4)
- You will need to download the v1.4 `homebrew_launcher.v.1.4.zip` release.
### Instructions
?> **Notice**
Your USB device will need to be formatted as FAT32. If your USB is not formatted to FAT32, use [GUIFormat](http://www.ridgecrop.demon.co.uk/index.htm?guiformat.htm) with 32k (32768) Allocation unit size to format it.
?> If you don't want to keep the game installed on NAND, you can use the Wii U's data management to move the game to an USB device.
