Don't buy Fifa 2003. It sucks! I have managed to get an illegal copy of Fifa 2003. I played it for 2 minutes and then deleted it from my HD.
Solution for your problem:
Download Virtual Drive from <A HREF="http://www.farstone.com" target="_new"> Farstone </A> and install it. Yuu will see a virtual CD-ROM in my computer. You will be able to load ISO images in this Virtual Drive. But you have to change the extention of your ISO files from ".iso" to ".vcd"
This program is 14 days trial. If you want to use more than 14 days, you will need a key. You can get it by buying it in leagal way, and the second way is- send a private message to me, and I will give you the key in reply.
