This project wouldn't be possible without the support from:

• Ethan Lee: Thank you for creating FNA!
• Artus Elias Meyer-Toms, Renaud Bedard and Ryan Kistner: I wouldn't be able to get my hands on the game without your support!

Usage instructions:

Preparations:

• Get yourself a fresh copy of Duck Game, f.e. via Steam... through Wine... or from a friend with Windows.
• Install mono-complete and libcurl3:i386 and ffmpeg (or matching) via your package manager.
  • ffmpeg, not "libav" / avconv.

Installing / updating:

• Download the latest released DuckGame-Linux-Complete.zip
• Extract the .zip into the Duck Game directory. Overwrite the original files when extracting. XnaToFna.exe, and DuckGame.exe should be next to each other; The old Steam.dll should be replaced by the one in the .zip.
• Open terminal in Duck Game directory, run chmod a+x ./mod.sh; ./mod.sh
  • mod.sh creates a backup of important files in an orig subdirectory, which XnaToFna needs. It also gives all files in the directory read-write permissions for all users, otherwise both XnaToFna and MonoMod will fail.
• Run mono DuckGame.exe OR Launch the game via Steam (add DuckGame.sh to your library as "non-Steam game").
• Be a duck with a gun!

The game stores its save data in ~/DuckGame, which is technically the same as on Windows.

Current collection of patches:

• XnaToFna gets the game running using FNA instead of XNA. Thanks to flibitijibibo for FNA. Without him this wouldn't be possible!
• Non-mixed-mode Steam.dll "proxy" to Steamworks.NET - this allows you to use Steam functionality natively... although it still contains a few holes. Working on it!
• More verbose fatal error logging that help you when patching the game.
• Create missing directories automatically. Does Windows just implicitly create the directories?!
• Automatically pass -nothreading because it's faster.
• Automatically pass -nomods because the mods would need to be relinked to FNA. This doesn't happen automagically yet.
• Fix ModLoader.modHash == null, not "nomods" when -nomods is passed. This also affects vanilla Duck Game and can kill Steam.

If for whatever reason something doesn't work, please create an issue on GitHub. I want this to work for everyone!
