Hi Han ! Stepping in for a quick tutorial :)
To extract (and save !) Your in-game sims, you will need SimPe. (If you are unfamiliar, you'll need winrar or winzip or any app allowing you to open archives.)
SimPe is available on MTS2, and doesn't require no installation. You may unzip it and run it !
• open SimPe (loading all your sims data may take a while)
• upper left corner, the tab "tools" > "neighborhood" > "neighborhood explorer" (? sorry, mine is in french :|)
• a new window should pop up, with all your existing neighborhoods displayed. Pick the neighborhood your extracted-to-be sims are in
• once the neighborhood is loaded (lots of lines and tabs ahah, don't worry about them), same as before: "tools" > "neighborhood" > "sim surgery" (again, long loading ahead)
• tadaa ! All your sims from that neighborhood are there. Quite a folk, eh. You may find them by their name. Once you click on the one you want to extract, go to the "sim patient" section (the first one on top) and click "use". From here, you can click "export" to save them as .package (basically, just saving their features) in your SavedSims folder !
If you want to turn them into Sims2Pack (so that their hair, outfit and so on are shared too) you may open the bodyshop, tweak them as you see fit and export them again from there !
I hope it is clear and if not, I'll try to explain better :)
THANK YOU SO MUCH FOR THIS INFO!!!! the next time i have a moment to setup my sims, i will look into this and try to extract Lasagna as a test!!!! :)
