> If you do not have the Xbox 360 Hard Drive Transfer Cable, please ensure that you purchase the correct revision of it for your console.
>
> The latest revision works with both original Xbox 360 and Xbox 360 S|E hard drives, but the first revision only works with original Xbox 360 hard drives.
>
> To know which is which, the first revision cable is gray, whereas the latest revision (which supports any Xbox 360 hard drive) is black.
> If you're using an unofficial SATA to USB adapter, you may need to remove the hard drive from its enclosure in order to connect it.
>
> For original Xbox 360 hard drives, this process is as simple as [removing some screws and cracking open the enclosure](https://www.ifixit.com/Guide/Xbox+360+HDD+Replacement/3430).
>
> For Xbox 360 S|E hard drives, this enclosure is glued shut and removing the hard drive may be an irreversible process!
6. Download [the latest release of Velocity](https://github.com/Gualdimar/Velocity/releases/download/xex%2Biso-branch/Velocity-XEXISO.rar) and open the `*.rar` file using [7-Zip](https://7-zip.org/download.html), then extract its contents anywhere that's convenient to you.
7. Create a new folder anywhere that's convenient to you for storing the game files.
> [!NOTE]
> If you're using Linux, skip to step 9.
8. Right-click `Velocity.exe` and click **Properties**, then under the **Compatibility** tab, tick **Run this program as an administrator** and click **OK**. This is required in order for the program to recognize the hard drive. You can now launch `Velocity.exe`.
9. You should see a **Device Detected** message appear on launch asking if you would like to open the **Device Content Viewer**. Click **Yes**.
10. You should now see a tree view of your hard drive's contents. Expand the tree nodes for `/Shared Items/Games/` (and optionally `/Shared Items/DLC/`, if you have the DLC installed).
11. Hold the CTRL key and click on **SONIC UNLEASHED** under the `Games` node, as well as the **Adventure Pack(s)** under the `DLC` node, if you have the DLC installed. Ensure all are selected before the next step.
12. Right-click any of the selected items and click **Copy Selected to Local Disk**, then navigate to the folder you created in step 7 and select it. Velocity will now begin copying the game files to your PC.
13. Once the transfer is complete, close the **Device Content Viewer** window and navigate to **Tools > Device Tools > Raw Device Viewer**.
14. Navigate to `/Content/Cache/` and click the **Name** column to sort by name. Look for a file that begins with `TU_19KA20I`, this is the title update which is required for installation.
> [!TIP]
> If you wish to verify that the contents of this file are correct, you may double-click on it to open it in **Package Viewer** and confirm that `default.xexp` exists inside, along with a folder called `work`.
>
> Once you've verified it, close the **Package Viewer** window and proceed to the next step.
15. Right-click on the file that begins with `TU_19KA20I` and click **Copy Selected to Local Disk**, then navigate to the folder you created in step 7 and select it. Velocity will now begin copying the title update to your PC.
16. Once the transfer is complete, you should now have all of the necessary files for installation. [Return to the readme and proceed to the next step](/README.md#how-to-install).
