After extensive testing, Wine/Proton loads cmd.exe exclusively from Proton's own installation (files/lib/wine/x86_64-windows/cmd.exe). Replacing the prefix system32 copy, IFEO registry keys, WINEDLLOVERRIDES, and Wine DllOverrides registry entries all have no effect — Proton's copy always takes precedence. The working fix: compile a tiny shim (GetCommandLineA scan for http URLs, write to C:\kyber_oauth_url.txt, ExitProcess(0)) and replace Proton's cmd.exe directly, backing up the original as cmd.exe.bak. The script detects size (shim ~9KB vs real cmd.exe ~1.2MB) to avoid double-replacing. Note for users: re-run setup-kyber-linux.sh after any Proton Experimental update since Steam restores the original cmd.exe on update.

# setup-kyber-linux.sh — Install the Kyber Launcher for SWBF2 (2017) on a
|
|
# native Linux Steam machine (headless or desktop) with Proton Experimental.
|
|
#
|
|
# Kyber is a community multiplayer client for Star Wars Battlefront II (2017)
|
|
# after EA shut down the official servers. It is a Windows app (Flutter/Rust).
|
|
#
|
|
# ── How Kyber's EA login actually works ────────────────────────────────────
|
|
#
|
|
# Kyber uses the "Maxima" OAuth PKCE flow:
|
|
# 1. Kyber starts a temporary HTTP server on 127.0.0.1 (dynamic port ~41413+)
|
|
# 2. It calls cmd /c start "" "<EA auth URL>" to open a browser
|
|
# 3. You log in on the EA page; EA redirects to 127.0.0.1:PORT/?code=...
|
|
# 4. Kyber's HTTP server catches the code and exchanges it for tokens
|
|
#
|
|
# Problem: Wine's cmd.exe crashes with STATUS_ACCESS_VIOLATION (0xC0000005)
|
|
# when called with a long EA auth URL. This blocks login entirely.
|
|
#
|
|
# Fix: Replace Proton's own cmd.exe (files/lib/wine/x86_64-windows/cmd.exe)
|
|
# with a tiny shim that captures any http URL from its command line, writes
|
|
# it to C:\kyber_oauth_url.txt, and exits 0. A Linux-side watcher calls
|
|
# xdg-open on that file to open the browser. Wine loads cmd.exe from Proton's
|
|
# installation, not the prefix — prefix replacements, IFEO, and
|
|
# WINEDLLOVERRIDES all have no effect, so Proton's copy must be replaced.
|
|
#
|
|
# After a Proton Experimental update, cmd.exe is restored; re-run this script.
|
|
#
|
|
# ── Why NOT to run Kyber inside Wolf / Games-on-Whales ─────────────────────
|
|
#
|
|
# Wolf runs Docker + Proton's bwrap nested. The double-sandbox blocks
|
|
# CLONE_NEWUSER which breaks WebView2, AND the inner bwrap prevents
|
|
# xdg-open from reaching the host display. Kyber's loopback redirect to
|
|
# 127.0.0.1:PORT also fails inside the container network stack. Use native
|
|
# Linux Steam instead — it's the supported path.
|
|
#
|
|
# ── WebView2 ───────────────────────────────────────────────────────────────
|
|
#
|
|
# WebView2 is NOT required for the login flow (Maxima handles that). This
|
|
# script still installs the WebView2 Evergreen runtime because Kyber may use
|
|
# it for in-app content rendering. Installing it causes no harm and prevents
|
|
# any fallback-related error dialogs inside Kyber.
|
|
#
|
|
# ── Headless note ──────────────────────────────────────────────────────────
|
|
#
|
|
# On a headless GPU box use Steam Remote Play: install Steam, configure a
|
|
# virtual/dummy display so Steam has something to render to, add Kyber +
|
|
# SWBF2, then connect with the Steam Link app from any device.
|
|
# This script warns if no display is detected at setup time.
|
|
#
|
|
# ── Prerequisites ──────────────────────────────────────────────────────────
|
|
# a. Steam installed and launched at least once (native, not Flatpak ideally
|
|
# — Flatpak works but paths differ; this script handles both).
|
|
# b. SWBF2 (AppID 1237950) installed and working with Proton Experimental
|
|
# (run setup-swbf2-linux.sh first).
|
|
# c. KyberLauncher.exe downloaded from https://kyber.gg saved to
|
|
# ~/Downloads/KyberLauncher.exe (or pass the path as $1).
|
|
#
|
|
# ── Usage ──────────────────────────────────────────────────────────────────
|
|
# chmod +x setup-kyber-linux.sh
