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 v1.0.0
|
||
|
||
Native-feeling **32:9 / 21:9 ultrawide** support for **Gundam Breaker 4** (PC). Forces **Hor+ FOV** (you see *more*, the camera doesn't zoom in) and disables pillarboxing. Confirmed working in gameplay at **5120×1440** on Linux/Proton (Samsung 49" Odyssey G93SC).
|
||
|
||
## Install (Linux / Proton)
|
||
1. Extract `GB4_UltraWide_Fix.zip` into `…/GB4/Binaries/Win64/` (next to `GB4-Win64-Shipping.exe`), or run `./install.sh` from the repo.
|
||
2. **Required:** add to GB4's **Steam → Properties → Launch Options**:
|
||
```
|
||
WINEDLLOVERRIDES="dsound=n,b" %command%
|
||
```
|
||
Without this, Proton ignores the loader and the fix only works in the lobby.
|
||
3. Set the in-game resolution to your display's native ultrawide res, fullscreen.
|
||
|
||
## Install (Windows)
|
||
Extract `GB4_UltraWide_Fix.zip` into `…\GB4\Binaries\Win64\`. No launch option needed.
|
||
|
||
## How it works
|
||
GB4 is Unreal Engine 4.27 and its shipping exe is SteamStub-encrypted, so a static exe patch isn't possible. This uses [SUWSF](https://github.com/PhantomGamers/SUWSF) + [Ultimate ASI Loader](https://github.com/ThirteenAG/Ultimate-ASI-Loader) to patch the decrypted UE4 `AspectRatioAxisConstraint` in memory at runtime — which is why it holds through missions (the `Engine.ini` trick alone reverts in-mission).
|
||
|
||
## Notes
|
||
- Do not use the HOR+ patch at 16:9 or narrower.
|
||
- You must own the game. This does not modify or circumvent any game copy protection.
|
||
- Uninstall: delete `SUWSF.asi`, `SUWSF.ini`, `dsound.dll` from `Binaries/Win64` (or `./install.sh uninstall`).
