I'm thinking of remake a few SS wrapped games I've done before with a smaller file size and hopefully faster emulated system.
Being not that experienced in what's a must in the System Folder I wondered if it's possible to copy an existing System and start from there.
I know Symantec's bootable CDs got those but are there other sources? And could they be more suitable ones for games?

The earlier wrapped games runs only under Mac OS X (I think?) and after 10.5.x(?). If interested I'll put up some links.
