a friend overseas backed up a PS2 demo game for me by putting the demo in his PC drive, and then copying the files onto the PC hard drive. These are the four files:

IOPRP280.IMG
SLPM_602.60
STREAM.BIN
SYSTEM

now with those files, can i create an ISO to burn onto a CD or DVD? The total file size is 225 megs, co i can put that onto a CD-R correct? Just wanting to know how to get if from my hard drive, and onto a disc. Thanks!
