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).

|
|
; 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.
