To add skins in The Sims 1, you need to download skin files (usually in .skn format) from a website or community that offers custom content. Once you have the skin files, place them in the "Skins" folder of your Sims installation directory (typically found in the "The Sims" folder under "Game Data"). After adding the skins, launch the game, and the new skins should appear in the character creation options. Remember to back up your original files before making any changes!
No.
Yes, if you go on the exchange and download some skins then they should be on your game:)
If you want a pet, get the sims unleashed. you can get new pet skins so i would say yes, you can
There are a lot of sims games, but the main ones are Sims 1 Sims 2 and Sims 3. There's a bunch of extentions and add ons, like Sims 1 hot date, Sims 2 buisness, and Sims 3 Night life.
Yes if you have the game and the registartion info that came in it
your computer must be messed up
No, expansion packs are made especially for each version on the game (Sims 1-3), only expansions made for Sims 3 will work, ones for the original game are not compatible.

Add-on.
Mod the sims. Search it, find it, click "skins" to get the download catalouge. You should have your disk in. Click on upload. Click on "sim". Then go from there. Mod The Sims.
No, The Sims 2 and The Sims 3 are two separate games.
Thru different custom sims websites. One is Modthesims.com. But what i do is just download sims from the sims 3 exchange. Look for a sim that has clothes, hair, and eyes that are not in the game by clicking on one and viewing the outfits and stuff. Then if you download that sims to your game, you might get lucky and get free custom content! I works, I have alot of skins in my game and I got all of them free from the exchange. Happy Simming :)
