Why do it this way?

I don't like having to launch a GUI launcher (Steam) in order to launch another GUI launcher (GRYPHLINK?) in order to launch a game. Wine and Proton are both open source projects, so we can use them outside of Steam.

Despite its name, umu-launcher can be called from the CLI, which means we can use a single shell script to launch the game. This shell script can then be tied to a .desktop file, making for a seamless experience.

Setup

Install umu-launcher

Gentoo

Install eselect-repository if you haven't already, it allows you to manage overlays.

eselect repository enable guru
emaint sync -r guru
emerge -a games-util/umu-launcher

Arch

pacman -S umu-launcher

Ubuntu / Debian

Go here, download the .deb file that corresponds to your distribution and install it.

sudo apt install ./umu-launcher_*_amd64.deb

Unzip the official launcher

NOTE: Modify the folder locations to whatever you have on your PC

1. Download it from the official website.
2. Extract the archive using p7zip
   • 7z x /home/bronze/Downloads/GRYPHLINK_*_endfield.exe -o/mnt/games/games/endfield_extracted/
   • Every distro should have this package.
3. Rename the $0 folder to launcher, you can probably delete the other $ folder.
4. Copy the launcher exe up a folder.
   • For some reason it doesnt like being in the launcher folder.
   • cp -v /mnt/games/endfield_extracted/launcher/1.2.2/Launcher.exe /mnt/games/endfield_extracted/launcher/Launcher.exe
   • The version numbers change every release, so 1.2.2 above may be something else.
5. Edit launcher-endfield.sh to point to /mnt/games/endfield_extracted/launcher/Launcher.exe (the launcher you just copied)
   • Also edit the location of the prefix to wherever you want it to be.
6. Run launcher-endfield.sh, install the game and enjoy!
