Certain things are not considered "creative works" under copyright law,
making them ineligible for copyright protection. This includes pinouts
(facts), descriptions of circuits (utilitarian), integrated circuit
lithography masks (utilitarian, but there's a separate field of IP law
protecting them), and character shapes (utilitarian).
However, many of these descriptions are substantial enough to be treated
creative works. A number of them include suggested applications. There
are situations where reproducing the descriptions may be permitted, for
example:
* The publisher may permit reproducing the entire datasheet for
reference.
* In some jurisdictions, fair use doctrine may allow the description to
be quoted in its entirety in a larger creative work (e.g. in a
research paper, patent application, or an original description of a
circuit utilising the device).
* Some jurisdictions allow reproduction of no more than 50% of a
creative work for inclusion in teaching materials.
I am not confident that these soure code comments qualify as a situation
where the long-form descriptions can be copied verbatim lawfully,
especially without reproducing copyright notices for them. If you want
long form plain language descriptions in the comments, you need to write
them yourself. That way, you will be the copyright holder of the
creative work, and you can make it availble under a permissive or
"copyleft" license.
* also made nld_devinc.h srcclean friendly.
* nld_devinc.h and lib_entries.hxx are currently not used. You can try
the automated build by changing NL_AUTO_DEVICES in setup.h to 1.
* photoply.cpp: Add HDD firmware dump to 'photoply98sp' (Seagate ST31722A)
* photoply.cpp: Add some notes about BIOS versions and rename the files accordingly
* Correct Taito ES5505 Bankswitching behavior
* Sample bank per ES5505 voice is actually taito_en.cpp specific
* Move external bank behavior into taito_en.cpp, Add getter for voice index
* Add precalculated ES5505 bank table for reduce performance issue, Add getter for CPU
* Added bgareggap loctest set to toaplan2.cpp
* Fixed YM2151/OKI level balancing for Battle Garegga and Armed Police Batrider
