It can be found in the install directory of the game in the subfolder "bonus content".
For the Steam version of the game the standard install path is the following under Windows: C:\Program Files (x86)\Steam\steamapps\common\Deponia Doomsday
To navigate to the install directory under every OS, simply rightclick on the game in your Steam library, choose 'Properties' and in the following popup select the tab 'Local Files' and click on 'Browse local files'.
Please note: The bonus material is not included in the Computer Bild Spiele version of the game.
There are two possibilities to do so.
1. This can be changed directly in the game by first navigating to the settings menu and then choose the tab for screen settings. The game will change the setting accordingly in realtime, no restart is required.
2. This setting can also be found in the Visionaire configuration tool. If you uncheck the fullscreen option, you can determine the window size through the panel above the checkbox. Save and exit the tool afterward.
This problem exists due to a drivers conflict caused by outdated drivers. In most cases, updating Realtek sound board drivers.
Special case, ATI Radeon X1950 / X1950 Pro / X1950 Crossfire Edition: This commonly used graphic board is, despite the manufacturer stating otherwise, not completely OpenGL 2.0 compatible. With Catalyst 7.8 or higher, this graphic board will not support OpenGL properly.
You can find the config.ini in the game folder of your local files:
Windows: C:\Users\*username*\AppData\Local\Daedalic Entertainment GmbH\Deponia 4\
Mac: /Users/*user*/Library/Containers/de.daedalic.deponia4.mac/Data/Library/Application Support/Daedalic Entertainment GmbH/
Linux: /home/*user*/.local/share/Daedalic Entertainment GmbH/Deponia 4
First of all, save your game while you are experiencing graphical problems. Close the game and please make sure that the Texture Compression of the game is turned off. You can check this in Steam by right-clicking on the game in your library, then select the Visionaire Configuration Tool. In there, you can disable the Texture Compression. After this, you should be able to play the game properly and load the savefile without having to deal with any graphic glitches.
If the issue isn't solved by turning Texture Compression off, please check whether you are using the latest graphic card driver. Very often outdated drivers are the source of a variety of problems in our games. The best way to update your driver is looking directly at the manufacturer's page of your graphics card. Since automatic Windows updates do not always find the latest drivers, we recommend looking for them manually.
This issue is caused by incompatible savegames and can be easily fixed by downloading the "savegame31" from this site. Please check your version before downloading a savegame. You can find the version number in the bottom left corner of your Deponia main menu.

After that, you are able to load the savegame in your in-game Deponia Save/Load menu.
This is a known issue which we're working on at the moment. You can continue the game properly by downloading the "savegame61" from our savegame database on this site.
