I've already started some work on the mission.lvl file and modified it, its very easy and you can get tutorials from
http://starwarsbattlefront.filefront.com/f.../Tutorials;6116. The hex editing guides are great for pc and the xbox. So far I've gotten coruscant to load with CIS as Jedi. I had to remove all the classes from the republic except for the rifleman and used 2 jedi on the other side but now it wont crash, i think it took too much memory. Ill put a message in the suggestions and see what happens, but BF2 people show your interest by posting in this forum.
If anyone is interested in the mission.lvl hacks heres some info. I took a modified mission.lvl file for the PC which pits jedi and clones vs eachother and put it into the BF2 directory in the xbox and overwrote the xbox mission.lvl file, and the xbox played the mission.lvl file for the PC.
I've started making my own hex edits although I'm still confused on how to make different sides play on the same side, like a republic clone commander on a team with a droideka vs a jedi and tusken raiders. So far I have been able to modify the teams and have jedis vs republic or alliance vs cis but thats it. No mixing and matching yet.
