I got some files to change language into Korean from CD version of this game which was released in Korea
But I don't know how to replace with those files because GOG version isn't same of CD version
GOG version seemed to renew some files from CD version, however Steam version does work !

Korean files consist of like this :

IHNMAIMS [folder]
- S.EXE
- SBH1616.FNT

IHNMAIMS_CD [folder]
- S.EXE
- SBH1616.FNT
- SCRIPTS.RES

Does anyone have any idea?
Please let me know what should i do :p
