ok use XCC Mixer to extract the ini files from INI.big (
http://xccu.sourceforge.net) than when you edit a file use notepad or wordpad depends on size of file than once edited place the edited file in Generals/Data/INI/file.ini but for all Faction files they go into Generals/Data/INI/Object/file.ini
also here:
FactionUnit.ini has all the infantry and vehicle stuffs like cost and build times
FactionBuilding.ini is the same as Unit just for buildings
than the rest are self explanitory like weapon.ini is for weapons and superpower.ini is for super weapons
hope that helps
