Spawn weapons on any map?

i've been playing with hex codes lately and found the m24 spawn code in the training.dat from the worlds.rez

i've tried putting it in other map.dat files (like snowvalley.dat) but since i don't know much (yet) about hex and this kind of modding...i don't know where to put it and how to control where the gun spawns.

i know a few people have done this successfully but they are being all hush hush about it >_< i can understand why though
