Cover the white bits in the bottom half of the texture file with black. That should solve it.
Visual Particles are stored in the Models bar files. Extract, and sort by type. They are the .PRTs.
These are code that run a series of .tga files (9-12 played in cycles) and can be varied by replacing the images through a hex edit of the .prt.
Somewhere in the code are things like size/speed etc. but it's inconsistent. Just pick a .prt that is about the size you want and create the .tga files. They work like 12/4/0/5 bitmaps using grey-scale for transparency.
