Ref: MOHAA Backup?
 

Have successfully backup both disks or so i thought.Disk1 installs great until it ask for disk2, then it say's "please check that the proper disk is inserted or specify a new path".Both disk's coped with all the file's like the original?But install's on my friend's PC and PLAYS. HELP!

MOHAA is using the very latest Safedisk 2 and is proving hard to backup. Only the Liteon 24 and 32 have been able to make 1:1 so far.
Considering you did make a 1:1 backup of it (cos u say it works in ur friends comp), then the problem is probably the ATIP protection.

Every CD-R has an ATIP, pressed cd's dont. If an ATIP is present then it won't play. It's only mainly Cd-writer that can read ATIP, so possibly ur using a cd-writer on your comp, and a normal CD-ROM on ur friend's comp.

You can use a CD-ROM to play the game on your computer or you can try to use Clone CD's 'Hide CD-R Media' function. I can't be sure if this will work as the new Safedisk 2.51.021 has been reported to get round Clone CD's 'Hide CD-R Media function' but this hasn't been connfirmed.
