OnimushaEnhanced settings.
OnimushaEnhanced settings.
This project aims to fix most of the game's biggest issues like XInput controller support.
Applying OnimushaEnhanced[1]
  1. Download OnimushaEnhanced.
  2. Copy the contents to <path-to-game>\.
  3. Run the game from OnimushaEnhanced.exe and adjust the settings.


To run this fix directly from Steam, add "<path-to-game>\OnimushaEnhanced" %command% to the game's launch options.
It makes possible to render the game at high resolutions.
Widescreen image is still stretched. Use Onimusha 3 Widescreen Fix to fix.

Bad Audio Mixing fix

Due to a bug in the PC port, sound effects during the gameplay are about 10 dB quieter than they normally should be.
This mod alleviates this issue by manually reducing the volume of all music tracks to equalize the audio.
  1. Download the archive here.
  2. Extract the contents to <path-to-game> and overwrite files when prompted.

Widescreen resolution

Use ThirteenAG's Widescreen Patch[2]


Properly scales HUD, Menus and FMVs in 4:3 aspect ratio for any resolution.
Disables the in-game Effect option as it could not be scaled correctly.
Alternative Widescreen Fix
  • For 16:9 Widescreen (1920x1080 only), download the patched executable from here.
  • For 21:9 Ultra-Widescreen (2560x1080 and 3440x1440 only), download it from here.
  • To Install, copy the executable to the game directory and overwrite the file when prompted.


Keeps the visual effects of the in-game Effect option intact at the cost of stretched HUD/Menu and FMVs.
Only a limited number of resolutions are supported for now.
Made by WSGF user jackfuste.


Remapping screen can be accessed with F2 in-game.

Japanese Voices

Japanese audio files are present in the game files (at least in the EUR retail version).
For in-engine cutscenes[3]
  1. Go to <path-to-game>\CAPCOM\ONIMUSHA3 PC\Image\stream\.
  2. Rename the current BGM_JPN folder to BGM_ENG and the old BGM_ENG folder to BGM_JPN.


Cutscenes in French remain unchanged.
In-game dialogues are unchanged, such as the voice of Ako and more.
For pre-rendered cutscenes[4]
  1. Go to <path-to-game>\CAPCOM\ONIMUSHA3 PC\Image\movie\.
  2. Rename japanese movie files by adding the "_ENG" suffix, and remove it from english ones.

Example #1: Rename mov90Bba.mpg to mov90Bba_eng.mpg (Japanese).

Example #2: Rename mov90Bba_eng.mpg to mov90Bba.mpg (English).

Alternative method[5]
  1. Download Onimusha 3 undub PS2 Audio.
  2. Copy the contents to <path-to-game>\CAPCOM\ONIMUSHA3 PC\.
  3. For the retail version, use this FMV Pack.


Audio files ripped from the PS2 version, almost all dialogues and FMVs are undubbed with subtitles.
Some voices lines during gameplay, such as the ones used by bosses are still in English.

Issues unresolved

Jacques performs only enhanced attacks when grabbing an enemy

The DualShock 2 controller used in the PS2 version had pressure-sensitive buttons. Since PC controllers did not have such feature, pressure-sensitive actions cannot be performed.
For example, Jacques would simply grab an enemy by lightly pressing the button; while he would perform a stronger attack by forcefully pressing the button. Only the latter action can be performed in the PC version.

Issues fixed

Can't remap controls

Install Microsoft DirectInput Mapper[citation needed]
