There are many localized crawls available on the Different Blu Ray versions of the first six films, from 2011.
The US releases have crawls in:
Latin American Spanish
Quebec French (Episodes 1-3)
Western European Blu Ray Set I have has:
Hungarian (Episodes 1-3)
Portuguese (Episodes 2-3)
Catalan (Episodes 2-3)
Polish (Episodes 1-3)
Greek (Episodes 1-3)
Japanese Blu Rays have:
Chinese (I think Cantonese) (Episodes 1-3)
Thai (Episodes 1-3)
Eastern European Blu Rays have:
Russian (Episodes 1-3)
Turkish (Episodes 1-3)
Czech (Episodes 1-3)
Slovak (Episodes 2-3)
None of them make any alterations to the English end credits.
There are likely som additional versions that I have not mentioned. Also, I have not checked the 2020 discs thoroughly yet, nor the Disney films.
I have the Russian version of both PT & OT. None of the opening crawls are localized. Czech, Slovak, and Turkish dub credits are not present for the prequels but Italian & Russian dub credits are present. OT has the same issue. Italian & Russian dub credits are present but the Czech dub credits are presented in a voiceover.
I have been looking for the Western European version for awhile. Would you mind sending me the texts and dub credits (if any) through PM ? 😃
