how to backup ps2 games help
 

how do i make back up copys i use clone cd i can not get them to burn onto disk it say`s game sud not the same

First make sure you are backing up a cd based game not a dvd based. If its a blue back then its cd based. CloneCd doesn't copy dvd based. Use PrimoDvd or Record Now Max for dvd based. You can read the PS2 CloneCd tutorial here
Also it is best if your burner supports Raw DAO 96, this makes exact 1:1 copies. You can check here
