Does anyone happen to have a collection of the loading screen files? Perhaps an archive collection? Perhaps the loadingloop files as well?

The Sims has been localised and translated to a very high standard. I think this would be a good way to recognise that.

I don't know if anyone's saved different versions of the UIText.iff (this would be what generates the scrolling text on the starting splash, among other UI text), but The Cutting Room Floor has the startup splash screens in all languages: https://tcrf.net/The_Sims_(Windows)...Loading_Screens (if you need other screens like the taxi screen those are probably somewhere in UIGraphics? I think?

(I'm sure the loadloop.wav for each game edition is also available somewhere. I just don't know an easy place to link it. I'm pretty sure the splash music for Vacation and Superstar is used elsewhere in the game under a different file name (or at least it was existent in my game's Music folder, which I'm sure of because it plays occasionally when I have my Sims music playlist on while streaming, and that playlist pulls from a copy I made of my all-EP install's Music folder).)
