Deus Ex

What works

Game works very well overall, minus evident "user input" bug below.

What does not

A bug known as the "User input bug" is present which causes user input to suddenly stop functioning at random intervals during gameplay.

I have not been able to play for more than 1 hour at a time because of this.
This issue should be resolved for wine 1.0, as it is a serious barrier to gameplay.

Workarounds

What was not tested

Finishing the entire game.

Hardware tested

• GPU:
• Driver:

Additional Comments

User input bug kills gameplay, and a reboot is required following this error. This issue warrants a bronze rating, because it effectively makes the game unplayable.

Installation

1. Install Wine
2. Configure Wine
3. Setup your environment variables:
   export WINEARCH=win32
   export WINEPREFIX=" ... "
   (for a 32-bit Wineprefix - the WINEPREFIX folder should not be pre-created)
4. Check your CD-ROM drive is mapped using:
   winecfg
5. Launch the setup:
   wine "D:SETUP.EXE"
   (Replace D: with whatever drive letter you have your CD mapped to in winecfg)
   The default installation folder is C:DeusEx.
   This will install Deus Ex version 1.002f as it was initially released in 2000.
6. Download the final release (GOTY) version 1.112fm update.
7. Launch the patch:
   wine ~/Downloads/DeusExMPPatch1112fm.exe
   (for example when you save the patch to a "${HOME}/Downloads" folder)
8. Remove the CD check when launching the game:
   sed -i "/^CdPath=.*$/d" "${WINEPREFIX}/drive_c/DeusEx/System/DeusEx.ini"
   The above command replaces CdPath=D: with a blank line in the DeusEx.ini file.
9. Launch the game:
   export WINEPREFIX=" ... " && cd "${WINEPREFIX}/drive_c/DeusEx/System" && wine DeusEx.exe ; xgamma -gamma 1

Out-of-the box the stock OpenGL renderer will generate a segmentation fault:

This BASH script will fix the DeusEx.ini file settings to correct this. Note it is recommended to use the newer OpenGL renderer (which is significantly better)

1. Create this script (credit to Morgawr, his original script was used as a basis for this):
#!/bin/bash




#export WINEPREFIX="❚❚❚❚❚❚"


export DEUS_EX_PATH

# Read install path for Deus Ex, from the Wine Registry.
# Note: this requires a first run, when DeusEx is installed under Steam.

DEUS_EX_PATH="$(
     wine reg query 'HKEY_LOCAL_MACHINE\Software\Unreal Technology\Installed Apps\Deus Ex' /v Folder 2>/dev/null \
        | awk '{ if (sub("^[[:blank:]]*Folder[[:blank:]]*REG_SZ[[:blank:]]*","")) print $0 }' \
        | dos2unix
)"

# Fallback to 'C:\DeusEx'

DEUS_EX_PATH="${DEUS_EX_PATH:-C:\\DeusEx}"

printf "Using DeusEx (Windows) install path: '%s'\\n" "${DEUS_EX_PATH}"

# Convert path from Windows to Unix format

DEUS_EX_PATH="$(winepath -u "${DEUS_EX_PATH}" 2>/dev/null)"

if [[ ! -d "${DEUS_EX_PATH}" ]]; then
     printf "DeusEx install path: '%s' ; does not exist\\n" "${DEUS_EX_PATH}" >&2
     exit 1
fi

# Patch settings to make the game work properly on OpenGL devices
# Uses the default DeusEx install path (for the current WINEPREFIX)
if ! sed -i -e '/FrameRateLimit=60/d' \
              -e 's/^GameRenderDevice=.*$/GameRenderDevice=OpenGLDrv.OpenGLRenderDevice/g' \
              -e '/^GameRenderDevice=OpenGLDrv.OpenGLRenderDevice$/a\FrameRateLimit=60' \
              -e 's/FirstRun=.*$/FirstRun=1100/g' \
         "${DEUS_EX_PATH}/System/DeusEx.ini"
then
     printf "Unable to update DeusEx.ini file: '%s'\\n" "${DEUS_EX_PATH}/System/DeusEx.ini" >&2
exit 1
fi

printf "Successfully updated DeusEx.ini file: '%s'\\n" "${DEUS_EX_PATH}/System/DeusEx.ini"

2. Make the script executable & run it:
   chmod +x fix_deus_ex_opengl.sh
   ./fix_deus_ex_opengl.sh
   (ensure your WINEPREFIX env variable is set)
