Welcome to Sun Sims, Jose!
As Miros said, all the stuff on Sun Sims is for The Sims 2, but if you have any questions about The Sims 1, she's a good person to ask!
The last great bastion of Sims 1 stuff that I know of is
M and M Needful Things.
Warning: Adult content on that site.
(M and M Needful Things also has large and growing selection of Sims 2 things, too.)
