A Deus Ex gameplay, challenge & general improvements mod.

GMDX attempts to refine and expand upon Deus Ex's gameplay, adding depth, ironing out flaws, rebalancing systems, and providing a steady challenge throughout the game. However, it's not just gameplay; expect modifications in the name of simulation, consistency, and visual/audio detail.
GMDX strives to expand upon Deus Ex's original design whilst remaining true to it.
Coming on two years now, development will not cease until the mod is impeccable. Please report feedback to assist in this goal, and if you would like to join the team and stretch the mod's grasp let me know, providing you are a suitable candidate.

Project Lead/Design by CyberP.
Programming by dasraiser.

v6 public beta released.

Battery Park Skybox

Feedback appreciated.
Includes a user-friendly installer courtesy of ggrotz which cuts the installation process in half. And of course v6 contains further new features and refinements such as redesigned recoil systems, further balancing of overall gameplay, further map improvements (primarily a focus on adding aesthetic detail this time around) and bug fixes.

Hold on, looking into it, stay tuned.

Question: did you choose to enable the music during installation?

Hmm OK.

Look in DeusEx\GMDX\Music and there should be the '2027_rooftop' music file. This is the one the game is looking for.
Now, when launching Deus Ex, Kenties launcher interface should pop up (if you installed it as part of New Vision as the guide advised), look in "data directories" and check the box for GMDX\Music.
If this doesn't work, copy the 2027 Rooftop file from DeusEx\GMDX\Music into DeusEx\Music,
Please let me know how it goes.

mmm ok. If I change the directory location:

deus ex+new vision: no problems

Deus ex+new vision+gmdx v6: I think that the problem with the shortcut get fixed but I still can't launch the game correctly:

the boxes of the mods starts unchecked(why?) and If I check any of them and press ok, the game ctd.

Are you running it via the shortcut or trying to double-click the EXE?

What is happening, exactly?

What I do:
1. Install deus ex goty(clean install, no files on program files, my documents, clean regedit and new directory location)
1.1. Launch the game, change res to 800x600, and color 32bits
1.2 Launch the game again, and change to color 32bits again(bug). Game works fine.
2. Install New vision+kentie launcher
2.1 Launch the game, the textures are installed and the game works fine. Also the launcher.
3. Install gmdx+music addon+fixes,etc
4. Run the game via the NEW desktop shortcut or via the gmdx start menu. Everthing except deusex.exe as the tutorial says.
