From 4d08990642abb43d5c98e9e0ff53e1ebc1b98003 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Wed, 18 Feb 2026 23:00:11 +0000 Subject: [PATCH 01/15] Implement Ghost Steam (Windows Runtime) architecture - Added `use_steam_runtime` toggle to `UserAppConfig` and Properties UI. - Implemented `ensure_steam_installer` to manage global installer cache. - Implemented `install_ghost_steam` with prefix sanitization and Proton execution. - Updated launch logic to support running official Steam client in background for DRM games. - Added path normalization and comprehensive logging for debugging.

This commit restarts the Ghost Steam implementation from scratch as requested: 1. Phase 1: Added `use_steam_runtime` toggle to `UserAppConfig` and the UI Properties modal with tooltip. 2. Phase 2: Implemented global `SteamSetup.exe` installer management in `src/utils.rs`. 3. Phase 3: Implemented `install_ghost_steam` in `src/launch.rs` with prefix sanitization and silent installation. 4. Phase 4: Integrated Ghost Steam into `spawn_game_process` with background launch and 5s wait time. Technical improvements added: - Switched to `tokio::process::Command` for non-blocking process management. - Added `-tcp`, `-cef-disable-gpu-compositing`, and SSL certificate environment variables for stable Steam connectivity under Wine. - Forced native DLL overrides (`steam.exe=n;lsteamclient=n;...`) to prevent Proton stubs from interfering. - Cleaned up legacy Master Prefix and AppID 0 logic to ensure a clean architecture.
