I wanted to see if I could extract the consoles loading UI for the pc version as a replacer if possible, I managed to edit the hex code of the sims 3 consoles .package files but i can't seem to find any "texture" files for the said UI only text strings to align the UI inside the UI.package file.

The UI I was looking for looks like this in game,

General Loading

Loading Map

Loading CAS

Got the idea after playing the console version and Sims Medival Since they seem to be more "Updated" looks for loading screens in Sims 3 based games.

Sims Medieval Loading Screen

If anyone knows if its possible to extract these textures/models or were to find them thanks in advance!!

No success looking through all the ps3's .package file all I could find was unused Sims 3 UI from the PC version.

Have you checked out some UI editing mods?

I did not know there was some for sims 3, would they work with the console versions package format? I'd be happy to try!

opening ui.package in S3PE just shows up an error code, but there’s something called Expected minor version '0'. Found '1'. if it’s just the version number that’s wrong, how do i change the number to '0'. (I know this post is like 3 years old but i hope i get a response from someone.) Thanks.

You can hex edit the header to change the version number. Unfortunately, in my experience I still haven't been able to successfully open any packages since S3PE fails to import any resources. But at least you can at least solve the version error easily enough. Perhaps you might have better luck than me.

EDIT: I was silly and simply forgot to untick "Use resource names". The edited package will load if you deselect that option, though, of course there will not be any names for any of the resources. This only seems to work for the first game's packages though. I still can't get the Pets packages to load.
