I create a batch file for each resource -- ie, REZ file. For DATA.rez it would contain this line:lithrez xv DATA.REZ .
The period is essential. Place the batch file in your MM9\data folder along with all the REZ files and double-click it. It should create a folder called DATA containing all the unrezzed files.
As you'll remember, the game will use these files preferentially to the ones in DATA.rez. Any changes you make to the unrezzed files will affect -- and possibly crash -- the game. I always keep copies of the original files in case I need to swap it back in.
That said, you probably won't have trouble with the DATA files. Are you planning on pursuing your weapon re-balancing?
