Regarding creating backup copy of SQ1 disk. You can use diskcopy to copy the original disk. It will state error regarding copywrite sector, ignore and continue. Once done, replace the agi and sierra.com files with the ones from the Space Quest Anniversary collection CD. It will then work. I own all of the original 1 – 6 big box versions and the anniversary collection CD. I like to use backup disks versus the originals and ran into this problem as well. For information purposes I have SQ1 Version #2.2.
