Sims 1 cheats:
rosebud;!; (extra money. I don't know how much, but if you fill the cheat console with ;!;!; after the rosebud command, then replace the last character with @, it adds 500,000)
move_objects on -- allows you to move things in use and delete things, such as newspapers, bills, plates on tables, etc. Be careful, as you can also delete portals, your mailbox, etc., and really muck up your lot. You can also delete your sim, go to live mode, and click on their portraits. This maxes their motives. But watch out. You'll lose skillpoints that you've gained within a certain timespan.
There are other cheats, but I haven't been successful with getting them to work.
