Emulation on a Mac

- 2009.08.12 - Tip Jar

Emulator (n) - hardware or software that permits programs written for one computer to be run on another computer (

An emulator is a very useful tool, and odds are that you have used one at one point or another, either for the purpose of entertainment or for the purpose of productivity.

Virtual PC for MacEmulators are often available free via download, are sometimes built into the operating system, and in rare cases are sold commercially - and offer excellent compatibility, such as Virtual PC (which requires a full licensed version of Windows to work). Emulators give you some serious options for changing how you use your computer.

There are legal and moral obligations involved with the use of some of these emulators, so be careful what you choose to emulate, unless you already own a copy of that particular piece of software and/or hardware.

Virtual PC for Macintosh is now discontinued, but it is still the most cost effective alternative to buying an Intel machine for PowerPC users.

Who Needs an Emulator?

Many people need to and want to use emulators. Anyone using a PowerPC G3, G4, or G5 Macintosh that may occasionally need to use an application or access a file that was built specifically for Windows may have to resort to emulating Windows via Virtual PC 7. Users also may want to emulate hardware to "time shift/space shift" hardware/software that they have already paid good money for.

Also, developers emulate various pieces of hardware while testing software in order to avoid any risk to vital data while having the ability to quickly analyze the software's performance. The iPhone environment can be emulated for those who develop for it.

Benefits of Emulation

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 applications to still work on a Mac that does not boot natively into a version of OS 9. This feature was eliminated from OS X with the release of Mac OS X 10.5 "Leopard" and has created a compelling reason to partition your hard drive with copies of "Tiger" (OS X 10.4) and "Leopard" in case you still need to use the Classic Environment for anything.

Another benefit of emulation is time and space shifting. The idea of time and space shifting is simply put as changing the time and place that you can typically utilize a product that you have purchased. The notion of is especially useful to gamers, who may want to space shift the use of a non-portable gaming device into a portable form that will allow you to play it on the go.

Gaming on a Mac Through Emulation

Two good examples of fantastic emulators for the Mac that allow you to space shift your entertainment would be MAME/MacMAME (a Multiple Arcade Machine Emulator) and PCSX, a Sony PlayStation emulator. Obviously, you can't haul your arcade cabinet around with you, and maybe you own an older Sony PlayStation unit but would like to play the games you already own when you're on the go. An emulator is not a bad choice in either circumstance.

Both MacMAME and PCSX provide a great solution for this problem, and the software is free (donation to their developers is truly appreciated). MacMAME allows you to play your old arcade games on the go, using ROM files that you must obtain to substitute for the hulking arcade cabinet you own, while PCSX allows you to play the Sony PlayStation discs you already own right on your Mac (not all games are compatible though).

Sony PlayStation Emulator for Older Macintosh Hardware

Connectix Virtual Game StationAn honorable mention goes out to the Sony PlayStation emulator, Virtual Game Station (VGS), developed by Connectix (the publisher of older versions of Virtual PC). Virtual Game Station was commercially sold for a short time in 1999 - until Sony unsuccessfully sued Connectix, bleeding the company dry in legal fees. Although Connectix won, they had to recover their losses to survive, so Sony bought out the rights to VGS from Connectix and quickly pulled the plug - truly a bitter pill to swallow.

VGS only works in Mac OS 8.1 through 9.2.2. It will not run in the Classic Environment of Mac OS X. It will, however, run compatible games at full speed on a 233 MHz iMac or above. Pismo owners rejoice - yet another reason to fire up OS 9 (this should even run fine on an original clamshell iBook)! If you don't have VGS and have an older iBook G3 or PowerBook that can boot the Classic Mac OS, it's probably worth trying! VGS and updates can still be found (1.4.1 was the last update). The original program can usually be found on eBay and

Compatibility is also quite decent since this was commercially sold. A compatibility list can be found on GeoCities.

Emulate Responsibly

Be careful! Downloading and/or using emulators is legal, but downloading applications, hardware configurations (BIOS), and game files (ROMs) that you do not own is illegal and could get you in serious trouble. Unless you own that hardware/software, or unless it is covered by the GPL (Gnu General Public License), or unless it is no longer protected by copyright, do not download it!

Use emulators at your own risk. As with any software, the manufacturer and/or creator of an emulator you use is not responsible for compromised confidential data, system performance loss, or loss of data. Always back up your important files and safeguard your confidential data with passwords and encryption.


As long as you play by the rules, emulation can be a good experience and gives you, as a consumer, the right to gain additional use out of something that you already own - or it may allow you to gain additional functionality out of a device you own. Without emulation, the world of computing and the world of gaming would truly be a more difficult place. LEM
