I pondered a bit more. If it's an ISO filesystem wrapped into some header and maybe a footer, then mount option -o offset= could help. To obtain the offset of the first occurence of "CD001", do offst=$( expr \ $( grep -a -o -b -m 1 CD001 cdimage.iso \ | sed -e 's/:/ /' \ | awk '{ print $1 }' ) - 32769 ) (It's the binary 1 before "CD001" which is normally at 32768. So grep will report byte position 32769 for "CD001" if offset is 0.) Then use the resulting number with the mount command mount -t iso9660 -o offset="$offst" cdimage.iso /mnt It might be that you get errors when mounting or when accessing the files in the mounted image. Check your kernel logs even if all looks good. --- (Do the year 1995 and the volume id "MSBSOLAR" mean that the game is "The Magic School Bus Explores the Solar System" ?) Have a nice day :) Thomas
