Ball of Wax

I have recently restumbled upon this. I was in the middle of looking what year Raiko was made, to determine the age of Raiko's gun (that I use in Nene). Realizing that it is 8 years old I also notice that the code is under this license.

This means Nene is actually released under the RWPCL as well. Does this mean just this version of Nene, and I can go and rerelease it under a more permissive license if I remove the RWPCL code, or is all of the code irrevocably RWPCL forever.

Because if it is the latter it also makes Rednaxela's code RWPCL, as well as Midboss and RougeDC by proxy. Which I don't want to force on him. Unless licenses are not retroactive, in which case those robots are safe.

All because of the very all encompassing "full source code of your system" clause.

I personally think if I wrote the code in question I should be able to license any particular version of it however I want, even if that causes the exact same code to fall under multiple incompatible licences.

Actually under reading up on copyright law. As the copyright holder of the additional code. I can chose to redistribute that code under a more or less restrictive license as long as it does not contain any incompatibly licensed code within its whole, regardless of any and all clauses defined within said licenses (including a strong copyleft). However if any of the code that I am not the copyright holder of, were to remain then the it would be unlawful for me to release it under any license that violates its license.

At least, that is as I understand it.

So Rednaxela is in the clear, as is Etna/Scarlet. But I do have to change Nene's license until such time I remove all RWPCL code from it, even then the older version of the code would still be RWPCL, as it contains Raiko's Gun (which is licensed under the RWPCL).
