how to backup Final Fantasy X

[Netslider]

There's no way I can invest in a DVD burner as they aren't available here in Portugal, as so for the DVD-R's.
I don't care about the movies because I find them boring, and about the voices, they are so badly done that some times I think Square didn't even make a casting or hired good voice actors. If someone tells me how to make the game fit one or more CD-R's, I'll be very thankfull.
