My prequel edits have Spanish subtitles thanks to a volunteer. Originally MalaStrana did the French subtitles but I’ve done them since.
I’ll be sure to do Spanish subtitles for this and future releases, and go back and do them for ANH-TLJ. The work and syncing is done, as I can mirror the English subtitles’ timing to the Spanish ones. It’s not rocket science but requires some time and attention.
Maybe I could help with some Spanish / Portuguese translation I think 😃 and maybe my native Polish
