>>> I asked you for the operating system not the processor, you have a G4 processor which is twice as fast as a Pentium III, and for the OS I guess youre using one of the latest ones..

I guess you dont know much about Macs and you have a pretty decent machine there (I just have an old G3).. Of course with such machine you can run a Snes rom and unzip a file. You just have to learn how to use it properly..
