#### **STEP 1 – Prepping the Dumper**

On your computer, [download the latest firmware package of the gateway launcher from their website](http://www.gateway-3ds.com/downloads). Within one of the folders (ex: /GATEWAY ULTRA 3.2.1 PUBLIC BETA/ for version 3.2.1) will be a Launcher.dat file. Place the Launcher.dat file on the root of the SD Card and place it into your 3DS. Then, in the 3DS browser, navigate to http://dukesrg.no-ip.org/3ds/go on the 3DS Browser. From here, your 3DS may display some weird colors or even say that it cannot load the page, but the Gateway loader should boot up regardless.

You can now copy this to your computer to clear space; this ROM file will **never** need to be on your SD card again. On a smaller SD card, you'll need that space for a later step anyway!

**NOTE:** If a game is greater than 4GiB, it will be split into multiple files when it dumps. Using generic names, it would be Game.3D0, Game.3D1 etc. On Windows 7, we can fix this easily by putting both files into the same folder, opening up command prompt and navigating to that folder. We'll use bravely default as the example here.

This will give you a single combined file that is your entire ROM dump. If you're certain you've done this correctly, you can delete the input files and just keep the .3DS produced.

The first thing you’ll need to do is download or compile a program called [Decrypt9](https://github.com/archshift/Decrypt9). Either method works.

Assuming Python is installed correctly, open up command prompt and navigate to this folder. A shortcut for this is to hold shift and right click on the background of the explorer window and then click "Open Command Window Here" in the options. It can be helpful when typing out long paths is annoying! Either way, just make it so that you can run the python file from the command prompt with the ROM following. For the ROM file, if you don't want to type out a big long path, you can just drag the ROM onto the command prompt and it will automatically fill everything out. Your command should look something like this.

So, now the beginning of the command is correct. Next we have to feed it all the xorpads. Add a space after the ROM dump and type "-e" and another space. Now find to the xorpad that has exheader in its name. You can either type out its name (if it's in the directory alongside the xorer program) or you can drag it into the command window (regardless of wherever it is at.)
