@kimchanjun it worked !! . Thanks. I found a way to hack dmg like the russian guy's clip but it won't save for me haha. unequip your weapon. Search 100~1000;6::5 then edit all (tick add, not replace) to 999 or anything like that. Equip a weapon then unequip again. I oneshot the big one by my fist haha.
Notice: The game wont save any progress after you hack. So this is just for fun until someone can figure out how to bypass that anti-GG. Sorry if bad english hurt your eyes
