Chaos Legion is a third-person fantasy hack and slash game developed and published by Capcom and ported by MiCROViSiON. It is loosely based on the light novel series of the same name by Tow Ubukata.

The game was originally released in Japan on March 6, 2003 for the PlayStation 2. The PC version is based on the later international versions, which features various difficulty and gameplay changes compared to the original Japanese release. The port was heavily criticized for the poorly implemented Disc check DRM used in earlier releases that rendered the game unplayable after installation, which prompted Capcom to recall copies of the game and re-release with the DRM issues addressed.[1][2] Other issues with the PC port of the game also includes texture corruption issues on modern video cards and frequent crashes during loading screens on Windows 7 or later.

A patch was released for the game, however, the other issues with the game requires third-party fixes to be addressed.

Field of view (FOV)
Borderless fullscreen windowed
Although Borderless Gaming works with the game, but it will stretch the image.[3] Mouse cursor also functions oddly in menus and stays on screen during gameplay.
Anisotropic filtering (AF)
Can be forced from GPU's control panel or through dgVoodoo 2.[3]
Anti-aliasing (AA)
Forced traditional anti-aliasing methods such as MSAA can cause some visual glitches with shadows.[4]
High-fidelity upscaling
See the glossary page for potential workarounds.

Increase rendering resolution

The low resolution depth of field (Focus Blur) effects can be worked around by running the game in a lower resolution from the in-game options while forcing a higher internal resolution with dgVoodoo 2.
Use dgVoodoo 2[3]
  1. Download the latest stable release of dgVoodoo 2, then extract the contents of dgVoodoo2_*.zip to its own folder in a convenient location on the computer (e.g. Documents).
  2. Run the dgVoodooCpl.exe, then configure the following settings from the General tab:
    • Adapter(s) to use/enable: <your video card>
    • Scaling mode: Stretched, 4:3 Aspect Ratio
    • Miscellaneous: Check Keep window aspect ratio and Capture mouse
  3. Now go to the DirectX tab and configure the following settings:
    • Videocard: dgVoodoo 3D Accelerated Card
    • Filtering: App driven or Force anisotropic (2x-16x)
    • Resolution: Unforced (uses the game's default resolution options) or Max (use the system's highest native resolution)
    • Behavior: Check Disable Alt+ Enter to toggle screen state (does nothing for the game regardless)
    • Antialiasing (MSAA): Off (forcing traditional anti-aliasing methods causes glitches with shadows)
    • Miscellaneous: Uncheck dgVoodoo Watermark and Force vSync (the game already uses Vsync by default)
  4. Click Apply and dgVoodoo 2 should save the configuration file to where you have it installed by default, then copy the dgVoodoo.conf to <path-to-game>. Alternatively, click the Add button and point the program to where you have the game installed to save it there.
  5. Go into the MS/x86 folder from your dgVoodoo 2 installation folder, then copy the D3D8.dll, D3DImm.dll, and DDraw.dll files into <path-to-game>.
  6. Launch the game. It should now render in a higher resolution.

Controller support

Right stick camera controls are incorrectly mapped to the analog triggers, which cannot be re-configured in-game without a workaround.
Use XInput Plus[3]
  1. Download and run XInput Plus.
  2. Set Target Program to ChaosLegion.exe.
  3. Go to the Key Assign tab and assign the following:
    • Left Stick: Check Mutliple Key, then assign it to Left Stick and DPAD.
    • DPAD: Assign it to None to unbind the camera controls set by game and avoid conflicts.
    • A Button: X. This is to allow the A button to skip cutscenes instead of X.
    • X Button: A.
  4. Go to the DirectInput tab, then check Enable DirectInput Output, then assign the following controls under the Key Assign section in the Basic sub-tab:
    • Right Stick: Z Axis/Z Rot
    • LT/RT: Button 11/12
    • Guide: Button 13
  5. Go to the Setting tab and go to its Dll Files sub-tab, and check XInput1_1.dll and XInput1_3.dll files. Then go to the Others sub-tab and uncheck Enable Init Beep to disable XInput Plus' confirmation beep sound.
  6. Click Apply to save settings and install the *.dll files into the game's installation folder. You should be able to control the camera with the right stick and use analog triggers.

Issues fixed

Texture Corruption

The game displays texture corruption on modern systems, causing textures to appear warped, shifted and completely out of place (e.g. trees being plastered with a window or wall texture). It has something to do with the game improper manipulation of non-power of 2 textures as explained in this thread.
Use dege's modified executable[3]


The PC version of Chaos Legion does not support hyperthreading and is prone to frequent crashes during loading screens.[6]
Force single core affinity[7]

Patching the game's executable with ImageCFG to run on CPU 1 is recommended as a permanent solution.

    "In porting the game to the PC, the addition of copy protection caused a major problem: While many games require a disc in the drive to load or run, Chaos Legion repeatedly asked for a disc no matter which of its two discs we used, and simply wouldn't run. Sadly, a Capcom spokesperson indicated that this problem didn't just affect a handful of people — "it resulted in 100% defective goods.""

    Experienced frequent crashes with the game on Windows 10 Home 64-bit in between loading screens prior to forcing single core affinity. After patching Dege's texture corruption fix executable with ImageCFG to force the game to use CPU 1 instead of using all available CPU cores on current setup, I was able to play the game for extended periods without it crashing.
