Note: This method doesn't work for multitrack game disks that I've tried, such as those that include audio files on separate tracks like Vib Ribbon.
Also don't go using this method to distribute copies of PS1 games on the internet. That's super illegal and uncool.
- Insert the game disk, wait for it to mount
- Open Disk Utility, right click the game disk, and choose Unmount
- Open Terminal and run
diskutil list
, make note of where the game disk was mounted (something like/dev/disk3
) - Run
sudo dd if=<disk> of=foo.iso
where<disk>
is the mount point we got in the last step (you can call the ISO whatever you want) - Download LiquidCD and extract it
- Open LiquidCD, go to the Others tab, and then click Choose a disk image… supplying the disk image you made last step, if asked, let it analyse the tracks in that ISO
