To use FUSION, you need:


To use the audio support, you will need:


To use SCSI devices, you will need:


To use the emulated CD support, you will need:


If you order Mac OS, make sure your retailer knows that you want "Generic" System software; that is, you want Mac OS that can be installed on any Macintosh. This is the only kind that will work with FUSION.

Do NOT use System software that comes with a particular Mac. It will NOT work.

Do NOT use pre-made HardFiles from other Macintosh emulations, (except from the Amiga version of FUSION)... they will NOT work. These HardFiles (sometimes called, "filedisks" or "bootfiles") may appear to function to a degree, however, you will experience problems using them. Please do not ask for technical assistance if you are using one of these files.. you will be wasting our time and yours!

99.9% of all problems encountered with FUSION are due to improper or improperly installed system software. It is essential that you read the section of this documentation concerning system software installation.

Mac OS 8 and newer only work with 1MB ROMs. Mac OS 7.6 will only work with 512K ROMs or 1MB ROMs.

How to create a shortcut to FUSION for Windows 95

In Windows, locate Fusion.bat and right-click on it. Then select Create Shortcut.

Right-click on the shortcut and select Properties. Click on Program, then click the Advanced button. Now click on MS-DOS mode, and make sure "Use current MS-DOS configuration" is selected.

If you need to change the contents of "CONFIG.SYS" or "AUTOEXEC.BAT" to get FUSION to work then you will need to select "Specify a new MS-DOS configuration" and make sure the space provided in the window contains the changes you require.

Then click OK (for Advanced), and OK again (for Fusion Properties).

If you have a command interpreter ("DOS Shell") like NDOS or 4DOS in your DOSSTART.BAT, you will need to remove it if you want the shortcut to immediately run FUSION. If you really want to keep your "DOS Shell" then you will need to type EXIT at the prompt when you start the FUSION shortcut.

How to exit or restart Windows 95

To exit Windows 95, click the Start button, then click Shut Down. Then click "Restart the computer in MS-DOS mode?" Then click Yes.

To restart Windows, type WIN at the command prompt, or press Ctrl-Alt-Del (if you use caching software that Windows does not like, for example, you will need to restart your computer).

Possible mouse problems

If your computer has a built-in mouse driver then you need not worry about the mouse.

Windows 95 uses its own driver for the mouse, so you may need to modify the DOSSTART.BAT in your WINDOWS directory to get FUSION to work with the mouse.

In Windows, locate Windows\Dosstart.bat and right-click on it. Then select Edit. Then add the following lines to the file:

set mouse=c:\mouse
c:\mouse\mouse.exe /q


If you do not have the DOS mouse driver nor a built-in mouse driver, then you will need to see your retailer about getting one for your computer.

If you find that the mouse operation is 'jerky', you probably have a low DPI mouse or the scaling factor is set incorrectly in your mouse driver software. Consult your mouse driver documentation for information on changing the x/y scaling.

How to get installed quickly

How to create a ROM image file

To do this, you really will need to own an actual Mac or purchase an Emulators ROM card with Macintosh ROMs pre-installed. You can also use ROM images from other Macintosh emulators such as SoftMac 2000 and Basilisk II. If you have already run the CopyROM utility bundled with SoftMac 2000, you can skip this section and use your existing ROM image.

Note that it is illegal for you to have a ROM image without the ROM itself. Unless under strict written agreement with Apple, there is no way around this. Do not borrow or lend ROM images!

Along with FUSION, we provide a utility called "ROMUtil". Its sole purpose is to create an image file when it is run on an actual Mac. As long as you do not use the Mac and the ROM image at the same time, this is perfectly legal.

Make sure you give the rom image a ".ROM" extension when you name it.

Due to a design limitation in Fusion, you must use 1 megabyte ROMs to run Mac OS 8.x. 512K ROMs will only support up to Mac OS 7.6.1 although you can use those ROMs with SoftMac 2000 to run Mac OS 8.x.

Notes on Extensions and Control Panels

You will not need all the Extensions and Control Panels. Some of them may cause problems. Keep this in mind when you do a normal Restart (with the extensions enabled).

You need to disable "A/Rose". This extension causes some serious problems if you leave it enabled.

Other Extensions and Control Panels will likely fail quietly, but for your peace of mind, you may wish to disable them, and save your system the bother:

QuickTime PowerPlug
QuickDraw 3D
Graphics Acceleration (any kind)
54xx/64xx Update
Auto Remounter
Button Disabler
Cache Switch


In particular, anything that is designed to work only on PowerMacs (like QuickDraw 3D), you can safely assume will not work with FUSION.

Features of the floppy support

Auto-detection is what causes that "clunk...clunk" sound in your floppy drive. When you insert a disk, it automatically appears on the Mac desktop.

To make the drive far less noisy, you can set the floppy detect time to 0. This will turn off head stepping, so you will need to press both Shift keys when you insert a floppy disk in order for the Macintosh to recognize it.

For more on why it makes that peculiar noise and how it works, read the following explanation:

For users:

Floppy drives are about as old a technology as punch cards. You would expect some limitations. The upshot of how it works is that you have to make the drive do something to know whether a disk has been inserted.

We make it move the drive head back and forth. This is far less annoying than leaving the motor and the drive light on all the time. Unfortunately, it makes a little noise. In particular, if you work in a quiet atmosphere, it can be quite noticeable.

For programmers:

Disk seeking updates the change-line status. We perform this feat once every 2 seconds (or whatever you have it set to). Since this is done at the hardware level, you would think that simply seeking all the way out and then sending a seek pulse every 2 seconds would be enough to detect a disk (this is the way "NoClick" on the Amiga works). Alas, the drive controller intercepts such attempts and returns "invalid function" whenever you attempt to seek out from track 0.

Features of the keyboard support

You should really have an "extended" keyboard for full support. An old keyboard will put you in "BIOS" mode which is a lot less intelligent. (See below.)

One nice feature of the keyboard support is the ability to use the "Windows" keys as command keys. Now, if they just swapped the positions between these and the Alts, it would look just like a Mac keyboard.

The keyboard (other than "Command" key) is mapped to equivalent Mac keys with the following exceptions:


When using the BIOS to map the keyboard you should be aware of additional problems:
