I've read that tutorial actually, the reason why I didn't use it was because I feared that compiling it using the module system would have deleted all other changes I made to the module i am modifing.
I was trying to make some "new" weapons available to various factions in the "Battle For Calradia" mod (for my own personal use) so I think that using the module system would cancel the rest of the mod. Is there an other way? or A way that would le me use the mod with the changes i'm going to make?
Not sure why you wouldn't use the module system... you'll need to redo your changes anyways with a new patch.
Anyways, I dug up some values from scripts.txt under game_quick_start.
The script, item, and troop reference IDs I have may not necessarily be the same as yours. Since you don't have the module system, you'll have to find all three of them hard way, by looking at the module system and seeing where they are referenced by other scripts, and then finding that script in scripts.txt and its reference value. By the time you're done that you might as well use the module system.
