what is the license for the source and data?

[alexmyczko]

the original website url is dead..

could you drop Originals/
and the Thumbs.db?

And create a release?

I've got a working Debian/Ubuntu package here:
http://sid.ethz.ch/debian/prototype/

The original website is dead, yes, and I don't have much info about the licence. I think "Public Domain" sounds about right, because the original author hasn't put any licence on its work.

I can remove the Thumbs.db

The Originals, I can , but why?

I can also create a release, sure.

[alexmyczko]

because they are not needed for the game? are you on twitter?

[ptitSeb]

Ok, I'll remove them (they were used before, but I converted the file to png and are not used anymore).

No, i'm not on twitter.

What is your real name and email address? I would need to write a file like this for prototype: https://metadata.ftp-master.debian.org/changelogs/main/p/protracker/protracker_2.3d.r147-1_copyright
and the copyright years?

The original Prototype windows is (c) 2005 from Ron Bunce (email removed, check your notification mail) (a.k.a xout).
My fork is (c) 2016-2018 Sebastien Chevalier (email removed, check your notification mail)

The original was informally released as public domain, see https://lists.freedesktop.org/archives/games/2009-October/000320.html

as the sourcecode
(http://xout.blackened-interactive.com/dump/new/ProtoType_src.zip) for
http://xout.blackened-interactive.com/ProtoType.html
doesn't contain any license, I contacted the author Ron Tuo and asked him,
under which license he distributes both src and datafiles.

He replied (I can paste his original answer if required) that he doesn't
care
and everybody is free to do whatever s/he wants.

On a 2nd email, where asking if it was ok to use src/data under
public-domain license,
he answered "No problem".
