Very simple.
1. Install Power ISO.
2. Once you install Power ISO, open CD1 using this program.
3. Once you open it up, it shows up all the files for the game. Make a new folder in your document for the game.
4. Click on extract, select all of the files, and transfer it to the folder that you just created.
5. Repeat the steps to CD2 and keep all the files from CD2 together with the files from CD1.
Enjoy!
