Please teach me to change REZ

Hello, everyone! I would like a master of education reform REZ have. I do not understand English, so I do not know to use GOOGLE translation translation is accurate. So please teach me how to change RF017.REZ, you taught me to change the time, please use simple words to tell me, because when a little GOOGLE translation is not correct.

I doubt anyone will teach you, and are you looking to just modify REZ with hex editor (which would take a million years to do), or the gun textures?
