First off I would like to thank Dav for his hack. This works perfectly for me and i use vista 32. Now, when i first tried this, i didn't work. After reading the thread, i realized that some ppl need the d3dx9_24.dll . If your hack doesn't work, download the d3dx9_24.dll.
Step 1: Download obviously
Step 2: Unzip with winrar or other programs.
Step 3: Copy the raw file into local C drive>nexon folder>combat arms.
Step 4: Make sure you have Dave's mpgh hack inside your folder as well
Thanks Dav once again.
