The original scramble.c carries no copyright notice and no license text, and
no formal grant accompanies it on the author's site, whose only statement on
the matter is:

    "All information is presented as-is, and may be used at your own risk."

mkdcdisc has described this code as public domain since the 2022 rewrite (see
the header of scramble.cpp). That characterization originates in this project,
not with the author, and has not been confirmed by him. It is recorded here so
that anyone auditing the licensing of mkdcdisc's third-party code sees what is
actually established, rather than inferring a formal dedication that does not
appear to exist.

Only the algorithm was taken: the scrambling of a Dreamcast boot binary is a
requirement of the medium, and the code here is a C++ rewrite rather than a
copy. See README.md for what differs from the original.
