On native Linux Steam, EA App self-installs via EAappInstaller.exe on first SWBF2 launch. Link2EA.exe appears in the Wine prefix without any MSI extraction. Script now checks for Link2EA.exe first and skips steps 2-3 (MSI locate + extract) if EA Desktop is already installed, proceeding directly to writing registry fix files and the launch wrapper.

# setup-swbf2-linux.sh — Fix Star Wars Battlefront II (2017, AppID 1237950)
|
|
# for native Linux Steam with GE-Proton (no Wolf / no Docker).
|
|
#
|
|
# What this does:
|
|
# 1. Extracts EA Desktop from the bundled ea_app.msi using msiextract —
|
|
# bypasses JunoConfigureRegistry, a .NET custom action Wine cannot run,
|
|
# which causes the full MSI installer to roll back.
|
|
# 2. Copies EA Desktop files (Link2EA.exe, EALocalHostSvc.exe, etc.) into the
|
|
# game's Wine prefix.
|
|
# 3. Writes link2ea_fix.reg and ea_services.reg into drive_c so they survive
|
|
# Wine prefix operations.
|
|
# 4. Installs a launch wrapper that imports the .reg files via Proton's own
|
|
# wine binary on every launch — required because direct edits to system.reg
|
|
# are overwritten when wineserver flushes to disk on shutdown.
|
|
# 5. Sets Steam launch options for SWBF2.
|
|
#
|
|
# Prerequisites — do these BEFORE running this script:
|
|
# a. GE-Proton10-34 (or later) installed via ProtonUp-Qt or manually.
|
|
# In Steam: SWBF2 → Properties → Compatibility → Force GE-Proton.
|
|
# b. msitools installed:
|
|
# sudo apt-get install -y msitools # Debian/Ubuntu
|
|
# sudo dnf install -y msitools # Fedora
|
|
# c. Launch SWBF2 once — wait ~10 seconds for the "Origin is not installed"
|
|
# error, then close it. This creates the Wine prefix and drops ea_app.msi.
|
|
# d. Your EA account is linked to your Steam account at ea.com (one-time;
|
|
# persists on EA's servers across reinstalls).
|
|
#
|
|
# After this script completes:
|
|
# Launch SWBF2. Let Vulkan shaders compile on first run (several minutes,
|
|
# only once). EA App authenticates via your linked Steam/EA account.
|
|
#
|
|
# Usage:
|
|
# chmod +x setup-swbf2-linux.sh
|
|
# ./setup-swbf2-linux.sh
|
