Sonic Unleashed Install Screen

The Install Screen is a cut feature from Sonic Unleashed that would've been used to install the game's contents to a PS3's hard-drive. It is fully functional in the PS3 version of the game, but it is inaccessible without modifying the game's executable; some of the files used for this installation process are present in the Xbox 360 version of the game and in the PC version of Sonic Generations, although in that game the install screen doesn't work anymore.

The leftover contents are in these locations on the PS3 version of Sonic Unleashed:

In-game

A person by the name of "Gael" was able to trigger the Install screen on the PS3 version of the game, this is how the install screen would look like in-game.

Install Folder

These 8 images are present in a folder named Install, and whenever the installation reached a certain milestone, they would get switched randomly alongside a new text message. These are also present in Sonic Generations inside bb2.cpk.

Text

The game displays the 8 images from before alongside some text, seemingly whenever a specified percentage of the installation process was reached, this text is present in Languages/English/Install/Install_list.fco:

Welcome to the world of
