lierbag28 is giving good advice in my opinion :-)
You risk destroying your floppy disks by continuously using them. So why not use a WHDLoad installer to get the game into hard drive and then put your original floppy disks safely away.
Go here
http://www.whdload.de/search.html and type Zool in the search box. Use the supplied installer to get the game installed to your hard drive. No need for code wheels and old games like Moonstone, Bio Challenge and D-Generation will work fine in Amigas like the A1200 and A4000 8-)
You can even press a single key, usually F9 or F10, to exit the game and get back to your Workbench screen, without the need for a reboot :-D
