Bionic Steam skips the Windows Steam client's first-run InstallScript processing, so EA titles never install the EA App. Parse installScript.vdf, honor each process's HasRunStringKey in the prefix registry for idempotency, and apply the script's registry strings and file copies. Limited to games that ship the EA installer bundle.

Detect EA App games by the installer bundle in the game dir - no per-game registration. The gamefix self-provisions the headless installer (cmd generated in code, the 245MB MSI copied from a sibling EA install; sc create pre-registration stops wine msi rolling back the install on fresh prefixes), repairs the EA registry that EA's own self-heal fails to fix under wine (broken SDK paths crash Link2EA in rpcrt4), keeps EA's Qt hosts on builtin WineD3D with the CEF subprocess on software rendering, and writes a launch script that starts EABackgroundService and polls it to RUNNING before invoking Link2EA.exe directly - Link2EA races a cold service and EA rewrites its protocol registry keys on every service start, so neither the wait nor the handler can live in the registry. The gamefix is re-applied right before the game session for EA titles only: installer sessions overwrite its registry work on their wineserver flush, and on a cold install the EA binaries only exist afterwards. EA's DirtySDK cannot resolve hostnames through bionic's resolver, so a prebuilt LD_PRELOAD shim (source: gamenative-dns-shim repo) routes res_query/getaddrinfo through Android's resolver for any EA App container. Accounts linked to Steam sign in silently via the Link2EA exchange token. Requires Proton 11.

…n-in Source the 245MB install MSI from the game's own EAappInstaller.exe when no copy exists: scan the WiX Burn bundle for the payload CAB, carve it, and pull the MSI out with imagefs cabextract. The install cmd now narrates each phase instead of sitting on a blank prompt, and opens the EA Desktop UI after a successful install so the user can sign in before the launch chain continues. The link2ea gate script is straight-line now: wine cmd nondeterministically deadlocks spawning children inside for-loops, and sc start already blocks until the service is up.
EA Desktop's UI issues the legacy XInput ListInputDevices request; replying BadImplementation is a fatal X error that kills the client before its window exists. Return a valid empty device list.

Adds EA App support for Steam titles that ship the EA installer bundle, so games like The Sims 4 now install and launch through EA Desktop instead of failing silently. Requires Proton 11.
