lemme explain it in an understandable English
First open your grand chase :: grandchase.exe
Let it patch, while patching, go to

and register.
There you can see the edited "script.kom", download it.
After your granchase.exe patcher finished patching copy the edited "script.kom" and go to your grandchase folder. Ex. C:\Program Files\grand chase ph\Stage
Paste it there and overwrite "script.kom"
after pasting it press "Start" in grandchase.exe patcher and done
If it doesn't work, then this one is not for granchase PH 笑笑
