In Belarus around 1997 - 1999 the unofficial pilot of South Park was dubbed and circulated with DVD. It was pretty popular and multiple people from my high school would watch and reference it. I distinctly remember watching it myself and know it has to have been dubbed in Russian or Belarusian because I didn't know English that well at the time but had no problems with understanding the show.
I know 2x2 in Russia for years after were producing russian dubbed South Park and have found multiple cases of early seasons being readily accesible but the pilot and the unaired pilot I can't find anywhere.
I would be very greatful for any information people can find on this as it was a very distinct memory of my childhood and I believe it's a cool piece of history.
