Korea, EU and NA has the same exact source codes, so it wouldn't make a difference for an edited hfs file unless we were talking about coding a lua for Mabinogi Heroes...which we are not.
And I haven't seen any hfs tools in ages nor have I bother to modify the game again. I am just speaking out of an experience and that someone here in MPGH has done hfs not to long ago but he did not want to leave any further comments to his success at what he was trying to achieve.
