I have no idea how much they were involved in these mixes. I assumed they just sent the stems to dub houses across the world and they would take care of it from there. I just don't know why they would listen to French, Spanish, German, Italian dubbings when it was just a question of sweetening the levels. But if they were that dedicated, cool!

As far as non-dubbed foreign releases, I would say it was the mono mix that was sent out. Just look at puggo's swedish 16mm (can't recall the name) and the various vhs broadcasts from the 80s in Europe : they have the mono mix.

But this is just a guess.
