i just dont know whats the diff of them? i just end up in images.dat on datedit
None.
original flingy.dat controls all the air unit movement of the game, but if you want, you can control ground unit movements too...
sprite.dat allows you to control the length of the health bar, the selection circle, and more..(I don't have datedit open @_@, don't remember)
image.dat allows you to control with grp to use, what shadow it uses, and weapon's fire color, and building and unit's destruction color...
None.
