For the PC port of Samurai Warriors 2 , achieving a modern widescreen resolution requires third-party tools, as the base game only natively supports 4:3 resolutions (up to 1280x960). Top Resolution & Widescreen Solutions
Because there are no official patches for widescreen support, the community relies on the following methods:
SUWSF (Simple Universal Widescreen Fixler): This is the most frequently recommended tool for the PC version. It allows you to force resolutions like 1920x1080 or 2560x1440.
Emulation via PCSX2: Many players prefer running the PS2 version of Samurai Warriors 2 or Samurai Warriors 2: Xtreme Legends through the PCSX2 emulator. This method natively supports widescreen patches and allows for upscaling to 4K with superior graphical results compared to the dated PC port.
Compatibility Settings: If the game refuses to launch at higher resolutions, right-click the SW2.exe, go to Properties > Compatibility, and check Disable fullscreen optimizations. Essential Performance Fixes
Frame Rate Limit: High refresh rates (above 60Hz) can cause the game speed to double or behave erratically. It is recommended to cap your monitor or the game to 60 FPS for stability.
Official Patch 1.1: Ensure you have the official 1.1 patch installed, which improves the frame-skipping feature and general graphical performance.
Controller Issues: To fix common controller bugs, use tools like XInput Plus to enable DirectInput output, which allows the game to recognize modern controllers properly.

Title: Samurai Warriors 2 PC Resolution Fix (Full HD / 1080p / Widescreen)
Body:
If you’ve tried to run the original Samurai Warriors 2 PC port on a modern monitor, you’ve probably noticed the problem: the game only offers low, 4:3 resolutions (like 640x480, 800x600, or 1024x768). This guide will force the game to run at 1080p, 1440p, or any custom widescreen resolution.
Important: This fix works for the original CD/DVD/ISO version of Samurai Warriors 2 (not the Xtreme Legends expansion, which has slightly different memory addresses). It also applies to the version sold on old digital stores (like the now-defunct Games for Windows LIVE version).
If you don't want wrappers, you can directly patch the SW2.exe file. Warning: Back up your .exe first.
Step 1: Open the Executable
SW2.exe in HxD.Step 2: Find the Resolution Values
20 03 00 00 58 02 00 00
20 03 = 800 (width in little-endian)58 02 = 600 (height)Step 3: Replace with Your Resolution Let’s say you want 1920x1080:
78 07 (little-endian: 07 78)38 04 (little-endian: 04 38)Replace 20 03 with 07 78 and 58 02 with 04 38. So the new string becomes: 07 78 00 00 04 38 00 00
Step 4: Fix the Aspect Ratio (16:9)
Search for the aspect ratio constant. Look for 55 55 55 3F (which represents a 4:3 floating-point ratio of 1.3333). Replace with AB AA AA 3F (this is a close approximation of 16:9, 1.7777).
Result: The game’s internal logic now thinks it’s supposed to output 1920x1080. This method is clean but less compatible across different PC versions (e.g., the Xtreme Legends standalone vs. the bundle).
SW2.exe (or SW2PC.exe).Every PC gamer should start here. Even if you want widescreen, this unlocks higher 4:3 resolutions.
The game's bloom and AA break with custom resolutions:
Even with the perfect fix, you may encounter issues. Here’s the fix list:
| Problem | Solution |
| :--- | :--- |
| Game crashes on launch after hex edit | You corrupted the executable. Restore your backup and redo the hex edit. Ensure you only change the specific 4 bytes. |
| Black screen but audio plays | Your resolution is too high for the game's buffer. Lower to 1920x1080 in registry, apply DgVoodoo2. |
| Textures are corrupted / rainbow colors | Old shader issue. Force the game to run in Windows 7 Compatibility Mode (right-click SW2.exe > Properties > Compatibility). |
| Mouse cursor stays on screen | Download "Cursor Lock" or use Borderless Gaming to force fullscreen window mode. |
| Widescreen works, but HUD is off-screen | This is a known bug. Use SW2Fix to manually offset the HUD margin in the .ini config file. | For the PC port of Samurai Warriors 2
If the game fails to launch or crashes upon resolution change, the Steam launch options can force specific parameters.
-fullscreen -w 1920 -h 1080This is the gold standard. Samurai Warriors 2 uses DirectX 8. Modern graphics cards don't love DX8. We will translate DX8 commands to DX9, then force a custom resolution.
Step 1: Download the Tools
Step 2: Installation
C:\Program Files (x86)\Koei\Samurai Warriors 2).d3d8to9.dll and place it in the same folder as SW2.exe.MS folder and copy D3D8.dll into your game folder (overwrite if asked).Step 3: Configuration
dgVoodooCpl.exe (the control panel) from the dgVoodoo 2 folder.Step 4: The .ini Tweak Even with the wrapper, the game’s config file needs a nudge.
My Documents\Koei\Samurai Warriors 2\.inputmap.dat with Notepad? No—better yet, open SW2Config.exe (the launcher) once, then close it. This creates the correct config file.config.ini or open SW2Config.ini (depending on your version). Add these lines:[SCREEN]
width=1920
height=1080
fullscreen=1
Save the file as Read-Only (right-click > Properties > Read-Only) to prevent the game from overwriting it.
Result: The game now runs at 1080p. However, note that UI elements (health bars, map) may be stretched, but the 3D battlefield will look sharp. Title: Samurai Warriors 2 PC Resolution Fix (Full
