Number 5 is a patch maker thingie right?
Well that one is used to make a patch
Though you need 2 files,
1 file with the English translation on it,
and 1 more with the original text.
Then Dream maker can automatically patch the Japanese file (which is the original) with the English file.
Though it's a feature which is not really helpful, as It cannot patch it if the line numbers are different. . making kinda "useless"
Hope this helped
