Thanks for your work.
Two things:
1)
$ /usr/bin/msgfmt -c --statistics -o ko_KR.gmo ko_KR.po
ko_KR.po:206: `msgid' and `msgstr' entries do not both end with '\n'
ko_KR.po:210: `msgid' and `msgstr' entries do not both end with '\n'
ko_KR.po:530: `msgid' and `msgstr' entries do not both end with '\n'
/usr/bin/msgfmt: ko_KR.po: warning: PO file header fuzzy
warning: older versions of msgfmt will give an error on this
/usr/bin/msgfmt: found 3 fatal errors
After correcting the above errors,
$ /usr/bin/msgfmt -c --statistics -o ko_KR.gmo ko_KR.po
227 translated messages, 1172 untranslated messages.
Your translation is in CVS now.
2) There was already a ko.po file in cvs, but it was last updated 27-06-2004, so it is most likely unusable now.
Keep on with good work, making aMule more familiar to korean people too.
