In general, the mod works. It's hard to notice much of a difference but it works.
I don’t know why I, instead of the author, should tell you how to install this mod correctly, but ok, I figured it out and will tell you.
Steps to install this mod:
1) Download any of the two archives of this mod (they are absolutely identical,
I don’t know why the author uploaded 2 identical archives of this mod...)
2) Unpack cheekbulgeeditV3_1.swf into Mods/$INIT$
3) Open “Mods.txt” there and add cheekbulgeeditV3_1.swf
4) In the main game directory (SDT - main folder where Loader.swf is located) find and open the Settings folder, unpack cheeckbulgeeditV3_1settings.txt from the archive there.
5) Done.
