I believe localized crawls were made for the unaltered original trilogy for German, French, Spanish, Italian, and Japanese. A localized Special Edition home video crawl was made for Navajo (Star Wars only).

I know localized credits exist, but I don’t know for which languages (probably the first five). I don’t know if dubbing credits were included – there was no theatrical dub for ROTJ in Japanese, for example – that was all-subtitled until the later home video dubs were made.

I don’t follow much beyond the unaltered forms of the original trilogy, so there could have been a great deal of movement on this front in the past couple decades.

Also, I would not count on the text in Project Threepio to accurately reflect the localized crawl, if you decide to go digging in there. IIRC, there’s a typo in the localized French crawl which is fixed in the subtitles. But if you want the text for the Navajo crawl, that’s verbatim (sans Episode IV: A New Hope), albeit not in fancy scrolling yellow text.

Also, if you actually have access to complete, non-mangled Original Trilogy (SE is OK) dubs in Hindi, Tamil, Galician, or Turkish, let me know ASAP, as I’m very interested in those – I have all of these, but with some glaring missing sections. Or if you have any other unusual original trilogy dubs I’d be interested in.
