MultiCAD

MultiCAD is a universal graphics DLL replacement for Sudden Strike, Sudden Strike Forever, and related games. It supports any custom screen resolution from 640x480 up to 3440x1600 (note: higher resolutions may be a bit laggy) and includes various bug fixes across different game versions.

Supported Games

| Game | Status | Versions / Languages | Fixes | |--------------------------------|--------|---------------------------|-------------| | Sudden Strike | ✔ | 1.0: de, ru, 1.2: en | 2 bug fixes | | Sudden Strike HD v1.1 | ✔ | en, ru | 2 bug fixes | | Sudden Strike Forever | ✔ | en, de, fr, ru, ch | 7 bug fixes | | Sudden Strike Gold | ✔ | en, de, fr, ru | 7 bug fixes | | Sudden Strike Gold HD v1.2 | ✔ | en, de, fr, ru | 7 bug fixes | | APRM | ✔ | 3.0, 3.1, 4.0 | 7 bug fixes | | TWO | ✔ | en | 7 bug fixes |

💡 Note: Audio Mixer Zero-Volume Fix restores the game volume in the audio mixer to full if it was set to zero. Applies to all versions.

Installation

1. Download the latest precompiled cadMulti.dll file from the Releases page.
2. Place cadMulti.dll into the folder containing the original cad*.dll files (typically the game directory).
3. Open sudtest.ini and set at least one SSDraw entry to cadMulti.dll. Example:

[Game]
SSDraw1=cad640.dll
SSDraw2=cad1024.dll
SSDraw3=cadMulti.dll

4. Launch the game.

💡 Note: If the game fails to launch or closes immediately with no error, it usually means the required Microsoft Visual C++ runtime is missing. You have two options to fix this:

1. Install the Microsoft Visual C++ 2015-2022 Redistributable: vc_redist.x86.exe.
2. Alternatively, use cadMulti_mt.dll, which works without installing any additional runtime (slightly larger than cadMulti.dll)

Configuration

Resolution Setup

By default, the game will launch in 1920x1080. To use a custom resolution, add a Resolution line anywhere after the [Game] header in sudtest.ini:

[Game]
Resolution=1600x900
SSDraw1=cad640.dll
SSDraw2=cad1024.dll
SSDraw3=cadMulti.dll

Restart the game to apply the change.
