Unofficial Shogun: Total War Collection Patch

An installer for Shogun: Total War Collection on GOG and Steam. It patches your existing game folder and lets you choose the fixes you want.

The installer looks for ShogunM.exe, makes a backup when it needs to change a file, and applies the selected options to your own install.

Included Fixes

Recommended:

• Terrain Movement Fix - installs dgVoodoo2 to fix click-to-move and drag-formation issues on modern Windows systems.
• Historical Campaigns Crash Fix - fixes crashes in certain historical campaign battles when timed reinforcements arrive.
• Voice Audio Fix - fixes voice clips cutting out across the game, including throne room dialogue, and other spoken lines.
• Limited Ammo Setting Fix - ensures the Limited Ammo setting works correctly in campaign and historical battles when disabled.
• Kawanakajima AI Behaviour Fix - fixes the Uesugi AI in the 4th Kawanakajima historical battle so its army no longer remains passive.
• Odawara Rout Pathing Fix - fixes routed Hojo units in the Odawara historical campaign battle so they retreat toward the nearest map edge instead of being sent into the wall and becoming stuck.

Optional:

• 120-Man Unit Balance Fix - rebalances 120-man unit sizes so recruitment cost, upkeep cost, and training time remain consistent with the 60-man unit size setting.
• Annual Harvest Report Audio Restoration - restores the original voice clips heard during the annual harvest report. Requires the voice audio fix.
• Throne Room Quote Randomiser - randomises throne room advisor quotes so each click can play any available line instead of following the same fixed sequence every campaign. Requires the voice audio fix.

Requirements

• Windows XP through Windows 11
• Shogun: Total War Collection from GOG or Steam
• A game folder containing ShogunM.exe

The Terrain Movement Fix is for modern Windows systems. Windows XP is not supported.

Usage

Download the latest installer from the Releases page.

Run:

Unofficial Shogun Total War Collection Patch.exe

The installer will try to find your Steam or GOG install automatically. If it picks the wrong folder, browse to the folder that contains ShogunM.exe.

Backups

When the installer changes a file, it creates a .unofficial-patch.bak backup beside that file. Existing backups are preserved.

To restore manually, close the game, delete or rename the patched file, then rename the matching .unofficial-patch.bak file back to its original filename.
