Who Needs an Emulator?
A great benefit to emulation is accessing legacy files and legacy applications. There are times when newer hardware and software is introduced and support for older versions is dropped. When newer hardware no longer supports the files that were recognized by an older operating system, emulation provides a distinct alternative. For instance, Macintel users have Rosetta built into Intel versions of Mac OS X, which emulates the PowerPC architecture and allows applications and files compiled specifically for PowerPC Macs to still work under OS X. Without Rosetta (or another emulator), these applications and files would not work on Intel Machines. The same can be said for those who access older applications on a PowerPC Mac that were compiled prior to Mac OS X. The “Classic Environment” is a built in Mac OS 9 emulator that runs within Mac OS X 10.4.11 and earlier on PowerPC Macs. This proves helpful in versions of OS X that support Classic Mode and allows those older programs and applicatio
