Backyard Football

I have this old game Backyard Football for Windows and Mac. I use to love to play it on my PCs but now since I got my Macbook, im testing it on here.... heres what the readme says about installing:

"Backyard Football


Minimum System Requirements
133Mhz PowerPC
System 7.5.3
32 MB of RAM
4X CD-ROM
Virtual Memory Turned On

Starting the Game

Before playing Backyard Football, close all open applications.
1. Insert the Backyard Football CD-ROM into you CD-ROM drive.
2. Wait for the AutoPlay window to appear.
3. Click the Play button.

Note: If necessary, a CD-ROM drive speed test may be performed the first time you run Backyard Football. This test takes a few minutes and requires no input from you.

Troubleshooting

If the game fails to start due to a lack of memory, you may need to enable Virtual Memory.

To enable Virtual Memory:
1. Open Memory settings located in the Control Panel.
2. Under Virtual Memory, turn Virtual Memory On.
3. Restart your computer.
4. You should now be able to launch the game.

If the Autoplay window does not open when you insert the CD-ROM, the Autoplay feature on your computer may be disabled.

To enable Autoplay:
1. Open QuickTime ™ Settings located in the Control Panel.
2. Select Autoplay from the menu.
3. Click the box next to the “Enable CD-ROM Autoplay.”
4. Close the window.
5. Re-insert the game CD-ROM.
6. The Autoplay window should now open.

To play the game without enabling Autoplay:
1. Double-click on the game folder located on your desktop.
2. Double-click on the Autoplay or game icon."


So I'm attempting the second option of playing without Autoplay but when I click on the Autoplay icon under the disc folder, it says "You cannot open the application 'Autoplay' because it is not supported on this system"...so what can i do? Is there a way to emulate OS 7? or sumthin to run it? thanks in advance
