Where to find the up to date catholic missals for each languages? I was able to find a latin missal (cf. MISSALE
ROMANUM, from 1962), but what I would like to find are translations in other languages (and the more recent "editio typica tertia"). I guess those should be all available on the vatican website, but where?

I am specifically interested in the Korean translation, as I am currently living there and it would help a lot in following the mass and learning the language.

Ideally, it would be best if I could find those in an editable format, so I can merge Latin and Korean in one pdf or ebook.

Edit : I found the Latin editio typica tertia on archive.org here. It is 1220 pages and it looks like the real deal. Maybe someone more knowledgeable can confirm?
This is the kind of edition I would like to find in other languages...
A search for the Missale Romanum on the Vatican website reveals that it is apparently unavailable, though the General Instruction for the Roman Missal seems to be available in multiple languages. This is in line with the English translation of the Roman Missal, which is unavailable on the websites of the US Conference of Catholic Bishops or the Catholic Bishops' Conference of England and Wales. It's not clear whether this is for copyright reasons or for some other reason.

According to the Union of Catholic Asian News, the Catholic Bishops' Conference of Korea has decided only within the last several weeks to authorize a translation based on the editio typica tertia. This decision does not seem to appear on the bishops' conference website.

If your parish pastor is unable to help you find a missal, perhaps you could check with the Bishops' Conference.
