+# 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
