Topic: Portable Widelands?

The Windows installer installs all files needed to play the game in the specified installation directory (IIRC the default is C:\Program Files (x86)\Widelands\). The homedir is the folder, where your personal data like settings, savegames, replays and maps are saved, which is C:\Users\<Username>.widelands\ (on Windows 7) by default but can be changed by starting widelands with widelands.exe --homedir=path/to/other/directory. You should copy your current homedir to you USB device and add a proper shortcut or batchfile to start widelands with the correct homedir settings.

The installer also creates some registry entries to link .wmf (Widelands Map File) and .wgf (Widelands Game File) with Widelands, so you can start them with a double click (and maybe some for the uninstaller). However this is just for convenience and not necessary to play Widelands.

Correct, Widelands does not touch the registry. That's why Shevonar wrote, that those registry entries are not needed.

The registry entries are installed by the Installer and removed by the Uninstaller. They start Widelands with some parameters to have a "double click to open a map in the Editor" feature.

Hi Community,

anything new on this topic? Tried --homedir and --datadir … both are not working and the game didn't start at all

Nach dem Studium von https://www.widelands.org/forum/topic/4513/

funktioniert folgendes:

--homedir=A:\Spiele\Games\DATA\Widelands
--homedir=A:/Spiele/Games/DATA/Widelands
