ini files

hey ppl,
i have seen what the ini file contain but if you edit them what happens?
does it just change the sizes of the mobs or what?

the .ini files simply store data, its the dat files u need 2 edit for sizes etc, they control client-side data, so if you changed the size of a monster on the monster.dat it changes the size of that monster on your screen and if you changed anything in the item.dat that would show on YOUR client etc :D

EDIT: not sure whether you can swap the mesh's around in armor.ini or in other things if that will change anything, never tried

so how do you edit dat files?
