First off could someone please clear up to me what "e" and "j" and "u" mean when refererring to versions of Final Fantasy.

For Nes/Famiconm, what is the difference in US and JAPAN versions of FF1? Is the latter available translated?

Is FF4 Easy Type available as a ROM in english langage? Is the Japanese FF4 available in English?

I take it there are only one version of FF2 and FF3? I have 2 ROMS of FF3 and the prologues are both different, I assume they have just been translated differently by different people?

Thanks if anyone can attempt to answer those questions.
