On the contrary, 4K would need 4 times the bandwidth to be of equal quality with 1080p, so upscaling 1080p to 4K would be pointless and would either result in pointlessly huge files, or reduced detail compared to the 1080p version due to compression.

As for the '95 Czech dubs (I actually recently discovered they were made for the 1995 THX VHS release, not the '97SE), I didn’t include them, because the translation is awful and I also always try to include the most original dubs possible. If anyone wants any alternate dubbing, they are, of course, welcome to mux them in themselves - the number of audio tracks is way too huge as it is, so I can’t include multiple dubs for each language on top of all that.

I’m actually thinking about releasing the next version with english tracks only and then including links for all the different dubs and instructions on how to add them.
