Xbox 360:Manually Installing Title Updates
Xbox 360 games often had title updates (patches) pushed after the game release. If you have a custom dashboard such as Aurora you can install title updates via the Unity Marketplace by selecting the desired game you wish to update and press Y (Details) and scroll down to the Title Updates section. There will be listed available title updates for the game. Note that you only need to install the latest.
Some games like Skyrim Legendary Edition will not work if the latest title update isn't installed. Note that not all games will have title updates available via the convenient Aurora Unity Marketplace menu. A good example would be Skyrim Legendary Edition. Fortunately, you can visit the Unity website and manually download the desired title update. To do so, search for you game and click on Updates. You will then be presented with a list for all versions of the game. The easiest way to know which version you need is to launch the game on your Xbox 360 and press the HOME button, on the black bar on bottom right of your screen you should see the Title ID, Media ID and Title Update Version. Note your Media ID and back on the Unity website select the appropriate title update for your corresponding Media ID. To install it, you will need a properly formatted USB media (key, ext. drive). The easiest way is to format it using your Xbox 360.
Once the title update is on your USB media, transfer it to you Xbox 360. Rule of thumb, title updates that are in lowercase (for exemple tu00000002_00000000) goes inside the Hdd1/Content/0000000000000000/TITLE_ID/000B0000 folder where TITLE_ID is you game's corresponding title ID. On the contrary, if the title update is in uppercase (for exemple TU_16L61V6_0000008000000.00000000000O2) it would go inside Hdd1/Cache folder.
Back in Aurora's title updates menu for your game, select the title update you just installed and activate it by pressing A (Enable). You can now launch the game and confirm that the title update is properly installed and activated by pressing the HOME button and on the bottom right of your screen you should see the title update number.
