So I want to edit some scripts such as setup teams and ambush in the mission.lvl, I have the conversion pack so I'd rather not munge my own mission.lvl from scratch as it will be incompatable. I'm going to try to compare the lvl from my project with the shipped one to correctly insert the code, but even if I can insert the now code correctly, I still need to know how to recompute the headers that dictate file size info. I recall a turtorial on this type of editing touting adding flyers to yavin 4 somewhere...

Any help is appreciated.

I can't help you with the hex editing, but you can use a v1.3 custom user script to override those scripts with your own versions. That might be easier.

not to hijack a topic, but i got a question that i have been trying to get answered for almost half a year. also this could help the original poster if he didn't know how either.

How do you use/make a custom user script? Also how would i set it up to also work on multiplayer? (i got a dedicated with cps that need locking)

From the v1.3 documentation, which you should always consult first: Is that what you were looking for?

Hidden/Spoiler:

Overview
* The UnOfficial v1.3 patch r102+ supports up to 11 custom user scripts. User scripts are loaded and processed at the start of game_interface.lua. This allows the scripts to control or adjust almost everything that happens ingame. For instance, you can create a script that does a few FakeConsole commands at the start of any map or a script that changes the server name to reflect the amount of people on the server.
* The UnOfficial v1.3 patch r129+ supports an unlimited number of custom user scripts. These scripts must start at number 11 and increment that number one at a time. If there is a break in the numbering, such as: user_script_12, user_script_13, user_script_15, and user_script_16, then when the game sees script 14 missing, it will stop checking for other scripts. Thus user_script_15 and user_script_16 won't be loaded.

Requirements
* SWBF2 mod tools
* v1.3 patch r141+ installed
* Basic understanding of Lua
* Basic understanding of how the game works

How To Do It:
1) First, you will need to read and understand the 'Munge A Custom LVL File.txt' document
2) Next, you need to pick a user script slot. The open slots start at 11 and must go up one at a time. Check your "GameData\data\_LVL_PC folder" and see which 'user_script_##.lvl' files you have. If the script name in the req file doesn't match the lvl file name, the script won't work.
x) If you are using a v1.3 patch below version r141, then only slots 0-10 are available.
X) This guide will use slot eleven: "11". If you plan to distribute your scripts to others, it is best to include the source code. This will allow each person to adjust the code for the amount of user scripts that person already has.
3) Configure your map to munge the custom lvl: "user_script_11.lvl" (see the custom lvl doc for help)
4) user_script_11.lvl must, at the very least, contain the lua script: "user_script_11". When your custom lvl is processed by the game, it will load only this script. You can always include more scripts or resources in the lvl if you need them, but the expected script (user_script_11) must load them (use ScriptCB_DoFile() or ReadDataFile()).
5) After you munge your user_script_11.lvl, copy it to the folder: "GameData\Data\_LVL_PC"
6) Thats it! Run your game and check its debug output. You should see it saying it found and loaded your script each time you load a map/level.

More Info
* For an example user script that runs a few FakeConsole commands when you play a single-player map (easy to remove the SP part), see "user_script_example.zip" in the "code eamples" folder of the v1.3 patch.
* You can use these scripts to better configure a dedicated server or enforce rules, such as 'no vehicles' by using the FakeConsole command 'Lock Vehicles' or a snipers only rule by listening in on AddUnitClass() and canceling any non-sniper units from being added to the team!

Is that what you were looking for?

i had read that but it didn't say how to get it to work online, only that it is easy to set for online...

Just what I needed, thankyou!

Just one question, where do I download the guide that you pasted from? Is it a game patch or something?

C:\Program Files (x86)\LucasArts\Star Wars Battlefront II\GameData\v1.3patch\docs\howtos. Some installations of the v1.3 patch don't have these docs. I'm not sure why.

And glad to help.
