Obtain a BIOS image of Mac OS 8. Before you can run Mac games on a PC, you must have a working BIOS image for Mac OS 8. This is a piece of coding that contains essential instructions for the Mac's functioning. To obtain it legally, you must have a 68K Macintosh computer.
If you have a 68K Macintosh computer, you can proceed with creating a BIOS image by copying the one that is already in the machine. To do this, you must use a ROM-dumping program. Several free ones, such as Stuffit Expander, are available online. Either way, just follow the prompts associated with the program, and the utility will take care of everything.
However, be aware that before you can run any ROM-dumping program, you must ensure that PC Exchange has been initiated on your Mac. This will allow you to transfer your BIOS onto a PC-oriented storage medium such as a CD, DVD, floppy disk, zip disk or flash drive. If you find that PC Exchange is not automatically installed on your Mac, you can install it on your own through the installation discs that came with your system. - 2
Download Mac-to-Windows emulation software. Mac-to-Windows emulation software is the ultimate secret when it comes to running Mac games on a PC. SoftMac is the most popular example of this type of software.
To download these programs, you must locate them through their respective websites. A link describing the most common Mac emulation sites is provided below.
Now, regardless of what link you choose, after you visit the website, look for the downloading section. Once you find the appropriate download links, right-click and select "Save As." The file will upload onto your computer automatically. - 3
Unzip the software. Most Mac-to-Windows emulation programs are compressed, which means you must unzip them before you can begin running Mac games on your PC. To unzip them, you can use the "Extract To" command in WinZip or use the unzipping utility that comes with Windows. This utility will appear any time you click on a compressed file. Follow the on-screen instructions to proceed with decompression. - 4
Install the software. This step is pretty self-explanatory if you've installed a standard Windows application. Basically, click on any file that has .exe as an extension or "install/setup" as a name. The program will install on the computer automatically. - 5
Run a Mac OS boot disk. Most Mac-to-Windows emulation software will require that you load a Mac OS boot disk before you can begin running any games. First, you must get the software. If you legally own a Mac 68K computer and you still have the boot disk, simply insert that into your computer right before loading your emulator. The boot disk will serve its purpose as long as it represents Mac OS 7.5 through 8.1.
On the other hand, if you do not have a Mac OS boot disk, you're going to have to download one and format it accordingly. Start by visiting Mes.Emuunlim.com, as it has a free one available for Mac OS 7.5. Just make sure you own a Mac, as it would be illegal to use this file.
After you download the file, use Aladdin Expander to decompress it onto a disk. On older computers, this disk would have to be a floppy; on newer ones, you can load these files onto a formatted CD or DVD. Either way, pop these disks into their respective drives before initiating the emulation process. - 6
Adjust your emulator's settings. In order to run Mac games on a PC, you must adjust your emulator's settings to allow for optimal performance. The methods for doing this will depend on the emulator you use. For example, some emulators (such as SoftMac) will bring up an "Autoconfig" wizard when you first run the program. You would have to tell the wizard which OS mode you want, where your ROM bios is, and other types of information.
Other emulators will expect you to adjust your settings by selecting "Properties" or similar commands from a Windows-like menu. Read the documentation that came with your emulator to know exactly what you need to do. - 7
Run an ISO image of a Mac game. Now you're ready to run Mac games, but you will need an ISO. This is the image format used for CD or DVD content. To create an ISO image, you will need Disk Utility. Use the "Convert" command to create the ISO. Make sure you save the file using the extension .cdr.
Once your ISO is created, load it into your emulator. Within seconds, you'll have what once seemed impossible--a Mac game running on your PC!
