With the official Sims 2 website not being up anymore, it’s not always easy to find the much needed patches for the game, so I’m going to host them here too. I grabbed them from the official site a long time ago, but misplaced the folder I saved everything into. The good news is, I recently found it.
Anyway, the patches are below. Inside each zipped patch folder you will find the patch and the patch notes for each one.
