As stated, I never done that.
We understand that, but that doesn't change the fact that the information was gained by reverse engineering, even if you didn't do it.
It's the same as with other resources - you need an absolute and completely legal sequence to be allowed legal use of anything.
If a game contains even a single sprite edited from a ripped resource, even if the edit and the rip were done by other persons, that game can be taken down for containing ripped resources and the developer might face court fines because of this - because it's the developer's responsibility to make sure he/she has licences to use for everything in that project.
How would I contact said programmer to raise inquiry regarding obtaining said documentation / license?
So far, I have yet to be pointed towards someone who is able to answer my queries properly. That s all I ask for
Enterbrain is the only source that can give you that info, and in the past they have ignored or refused every such question.
It might be that they change this in the future (they are working on other improvements like large resolution and mobile export after all, so they might decide to work on encryption later), but that remains to be seen.
Kinda get the feeling that this thread is starting to turn into 'what your doing is wrong/illegal' when really, the thread was created to find out if it was illegal and if so, exactly what was illegal and also, to find out how to perform similar actions without it being so 'illegal'.
That is partially because you insisted that you didn't do anything wrong when using illegal data from the internet instead of focusing how you could get the info in a legal way...
However, I can tell you one thing:
You will NEVER get that information by asking on a public forum - there are too many problems with public posts. You allways have to remember that legalese is a different language from english.
What you need to do is get a private contact to Enterbrain, then sign an offered non-disclosure-agreement (if THEY decide that you could help them with the encryption problem or any other problem that requires direct access), and then get the info by private channels.
Remember: The developer for the test-game for the mobile exporter wasn't allowed to even talk about the existance of said exporter until the completed game was advertised by Enterbrain itself.
I personally believe that the more publically vocal you are about that theme, the less chance you have of being selected to work with them on the problem. However, so far there have been no specifics so you might still have a chance if you can give EB a good reason why they should work together with you to solve the problems.
