How do I save Sims?

[Whisper]

Like Sims that are already in the game or ones I make in bodyshop because I'm trying to do that Multi-PT Mod thing to make the pollinations different and such. Like it tells me to go to my savedSims file but it's empty. I'm sort of a noob with all this custom content and modding thing, I just started doing it. Please help.

You can extract them out of the game using SimPE. It's actually quite easy to do.

- Here's a small tutorial on MTS2 on how to do it. Here's another one, although the images are broken.
- And here's the link to where you can download SimPE
