# mkisofs sorts file names alphabetically, it does not place the files in the
|
|
# generated directory descriptors the order given on the command-line.
|
|
#
|
|
# The "1st read file" must be physically placed at index [2] (after the "self"
|
|
# and "parent" entries) of the root directory, and so must be alphabetically
|
|
# lowest in the list of files.
|
|
#
|
|
# Additionally, the sega bios appears to reject disks that have a single
|
|
# file. This is presumably incomplete enforcement of the "required" smp_cpy.txt,
|
|
# smp_abs.txt, and smp_bib.txt files. A disk with a single file is presumed
|
|
# invalid (but >=2 files appears to be ok). The content of these files does not
|
|
# appear to be checked.
|
|
#
|
|
# Rather than insert a dummy file to "trick" the bios, I decided to include
|
|
# these files as specified in the manual (perhaps there are some bios versions
|
|
# that do check this).
|
|
#
|
|
# `-graft-points` is used to enable the "path grafting" pathspec syntax.
