Files to CDI ?!?

[RaMa]

First of all sorry for my bad english...

I tried to copy my friend's working Crazy Taxi to a new disc. Just take all the files from the CD and burned them into a new 650 Mb disc. Not used any CDI files or something like that. Of course it didn't work on my DC. I have all the files for game in a CD but it is not working.

How can i make a new CDI to burn the game from these files?
Can i make this CD work?
Please help 'cause i don't want to redownload Crazy Taxi!!!
