Ya I'm having this problem as well.
I want to move my CHaracter Prince Phillip to 204,83 for example,

i put in:

move_character "Prince Phillip", 204,83

move_character "Phillip", 204,83

move_character "Prince_Phillip", 204,83

everything I just says:

"err. character not found" or something.

What am I doing wrong, why won't these cheats work?
