First time getting a Mac and I would like to download classic games that are recommended. I have 8MB ram with OS 7.5.5. What games are recommended? Where should I download them? Can I download classics like Lode runner, Winter games, etc.. that will work with my system? I have a Macintosh Floppy Emu from: http://www.bigmessowires.com/macintosh-floppy-emu/ I see some files are .sit and .image but I need .dsk, correct? Thanks!
