How To Run Pokemon On Mac Where I Can Download A Pokemon Game To My Mac?

Where I can download a pokemon game to my mac? - how to run pokemon on mac

I know I need to download an emulator, but a certain kind? And where can I download? Well, I viruses in one of the sites and no longer needed. I do not really like this game that I download, just want to play pokemon.

More information.
I have an iBook G4, its implementation in OS X Panther
I am currently on dial-up, but fast enough TBH.
Any help would be great!
Thanks
