Pixar Demos - widberg/fmtk GitHub Wiki

The Cars and Ratatouille demos from the WALL-E game disc can be launched using FUEL's GameSetup.exe with minor changes. If the necessary conditions are met then a button labeled "HELIPORT" will appear in the GameSetup.exe window. Upon clicking the button a smaller window will pop up with the title "Please wait while the shaders are being processed." and two buttons in it titled "Cars Demo" and "Ratatouille Demo". These buttons will be greyed out if the corresponding demo is not installed, otherwise, they are clickable and will launch the respective demo.

The first condition for the "HELIPORT" button to appear is the game_name field in setup.cfg must be L"Demo". This requirement can be patched out with the following x32dbg patch file, which nops out the check.

>gamesetup.exe
0000A77E:74->90
0000A77F:17->90

The other condition is that the nCmdShow argument of ShowWindow must be patched from its hard-coded value of SW_HIDE to SW_SHOWNORMAL so the button actually shows up. This requirement can be patched with the following x32dbg patch file.

>gamesetup.exe
0000A781:00->01

Alternatively, if the game_name is not L"Demo" then the game will check if you have either of the two demos installed and call EnableWindow on the button if you do; however, the button is never shown. This is a holdover from WALL-E where the button would always be shown but would be grayed out if neither of the demos were installed.

Since GameSetup.exe loads text strings from trtext and this feature was not intended to be accessed normally, the names of the button and window use unrelated translation strings, sharing the same id as the strings in WALL-E, that do not make sense in this context. As we can see in the screenshot from WALL-E below, the button is intended to be called "Bonuses" and the title of the pop-up window should be "Launch demo".
