Gundam Breaker 4 UltraWide Fix v1.0.0

32:9 / 21:9 ultrawide support for Gundam Breaker 4 (UE4.27) via SUWSF +
Ultimate ASI Loader. Forces Hor+ FOV (AspectRatioAxisConstraint=MaintainYFOV)
and disables pillarboxing, patched in decrypted memory at runtime so it holds
through missions (the exe is SteamStub-encrypted; a static patch is impossible).

Confirmed working in gameplay at 5120x1440 (Samsung Odyssey G93SC) on Proton.
Requires WINEDLLOVERRIDES="dsound=n,b" on Proton so the loader injects.

Includes: patch/SUWSF.ini, Proton installer with clean uninstall, release-zip
builder, and runtime dump/verify tooling. Third-party bundles under MIT (see
THIRD_PARTY.md).

+;  Gundam Breaker 4 - UltraWide Fix (SUWSF patch)
+;  Target display: Samsung 49" Odyssey G93SC  (5120x1440, 32:9)
+;  Engine: Unreal Engine 4.27  |  Exe is SteamStub-encrypted -> runtime patch
+; ==========================================================================
+; Your screen resolution used in patch calculations. "auto" reads primary
+; display; set explicitly if auto misreads under Proton/DPI scaling.

+; --------------------------------------------------------------------------
+;  WARNING: PATCHES BELOW. These are CANDIDATE UE4 patterns adapted from
+;  known-good UE4 fixes (Trepang2 / Lies of P). Because GB4's .text is
+;  SteamStub-encrypted on disk we cannot verify the exact bytes statically;
+;  SUWSF scans the DECRYPTED image in memory at runtime, so if GB4's UE4.27
+;  codegen matches these generic patterns they apply directly.
+;
+;  If a patch reports 0 matches (see SUWSF log / no visual change), run
+;  tools/dump_decrypted.sh while the game is running and send me the dump so
+;  I can derive GB4's exact pattern. Each patch is independent - a miss on one
+;  does not stop the others.

+
+; [1] HOR+ FOV  -- the primary fix.
+; Forces ULocalPlayer AspectRatioAxisConstraint to 0 (AspectRatio_MaintainYFOV).
+; This makes the camera keep VERTICAL FOV constant and expand horizontally
+; (Hor+), removing the zoomed-in feel at 32:9. Do NOT use at 16:9 or narrower.
+; Value BA 00 00 00 00 = "mov edx, 0" ; 90 90 90 = pad nops.

+; it can double-apply with patch [1]. Enable ONLY if [1] misses and you still
