Command and Conquer Shockwave, where are the costs of the armies stored?

In Command and Conquer Generals: Zero Hour, the armies costs, build time, etc . are stored in the file INIZH.big , so if you modify them you can change the building costs, building time, etc, of soldiers, tanks, etc. Now I want to do the same for the mod Shockwave, which apparently uses the same folder for installation (the executable file is installed in the Command and Conquer Generals: Zero hour folder), but I dont know which file I have to modify for changing the building costs, apparently modifying the original INIZH.big from Command and Conquer Generals Zero Hour doesnt affect the mod.

Then, where are the costs of the armies stored?
