Cheat mod for Rebel. ALL modifications done to Rebel side ONLY
Instructions:
Go to the main SW:EAW folder and place the unzipped XML folder in your GameData\Data\  folder. 
In other words all of these files will reside in  GameData\Data\XML\  
CHEATS:

Space battle Size changed to 100 (or 50 if you get the other file), Land Battle units increased
Following Planets Modded that add tons of money, 
added population caps, and have 8 build spaces, level 5 bases:

Alderaan
Yavin
Wayland
Mon Calamari


Instant Build: All Space and ground unit build times sped up, all build times for structures sped up.
Bombing runs on planets recharge rate sped up. C3PO/R2D2 Fast Tech steal.

Most of this should ALSO work in Skirmish.

And THATS IT.  IF YOU WANT TO REMOVE the MONEY CHEAT:

Open Planets.xml then search for one of the 4 planets listed above (like Yavin):



then look under that until you see:
5000

Thats how much cash you make each year JUST from Yavin with that cheat mod.
Just search for each instance of  in the Planets.xml file 
for each planet I changed and if it seems high just change it back to a smaller value. 
That way you can get rid of the money cheat if you want.
