What exactly does this line do?
Checks=(FName="OpenGL32.dll",MD5="file not allowed",MD5Type=2,Optional=True)
This will disallow the file OpenGL32.dll in the \System directory. Of course you can also specify absolute or relative paths in FName. It is important that you use MD5Type=2 and Optional=True.
I added it because of most Tweaks you need to use OpenGL and not many players use it anyways.
But it seems not to do anything.
I tested it and still be able to use opengl .
