Injecting a new shadow texture

Does anyone know how I can inject a new shadow texture?
like a pure white circle instead of the black one for the simple shadow.

goto %conquerFolder%\c3\Effect\shadow all ur effects for shadows are there

anyway to make like fastblade aimbot by checking shadow and aiming?.. or by packet sending! like gunbound -.-

Nyar, if you know how to edit the file to change the color of the shadow, please tell us.

you gotta get the nvidia plugin for photoshop to open dds files. however the shadow file that ultimatehacker suggested is wierd, i cant seem to figure it out. Even when the file is deleted the shadow still appears... so thats why im asking.
