Need Someone to Convert 2 VRCW Files

[Cyber-Skeleton]

I need these two world for a project I am working on but cant manage to get them into unity. I turned them into .unitypackage files with S.A.R.S. but when I bring them into unity nothing happens. Can Somebody else get it to work?
The two worlds are:
The McMansion By spookyghostboo & Hat in Time Spaceship By Peculiar Sana
