Hiya Bio,

As mentioned your only option is an emulator, but reports have been around that it runs Jazz fairly well.
So far there is no and there never has been a native *nix-version of Jazz. We, the council, could give it a look once we get our hands on the source-code. But I doubt there'll ever be a conversion (from what I've heard Jazz2 is heavily Win-code based. E.g. for the Mac version they had to build a new engine from scratch).
