this is my question

You dont add gsc's to the FF viewer you just rename the gsc's that are already there. Make sure that if you rename them that is is the exact same amount of characters as the original gsc.

i know this.
i can edit raw/maps/mp/gametypes/etc.gsc
but i want to add one gsc
for example:
raw/modz/etc.gsc i can see other mods with this and i want add one

You can't. If you did, it would require a lot of coding and a lot of binding to get it to run on the game. It would be quite complex.
