Does anyone know of a program like simzip for the sims 2?

I don't know of one. But it's really quite simple.

Just place all unzipped files, which have names ending in .package, in the folder:
My Documents\EA Games\The Sims 2\Downloads
If you're really clever you can make a shortcut to that folder and place it on your desktop, like wot I have! You can then drag and drop package files onto the shortcut icon ... easy peasy. ;)

There are also Sim2pack files. These are unzipped using a program that came with Sims 2.
