Hi everyone!
I have currently 2 questions:
- What license is JA2 under? I couldn't find any COPYING or License files...
- Was there ever an attempt to port this over to POSIX systems?

The license sounds somewhat awful...
Doesn't seem to be GPL compatible at all.
I guess you have to dynamicaly link against SDL because of that?
There doesn't seem to be a paragraph demanding that the modified source is made available under a compatible license?
What license are your modifications under? Did you have the assistance of some lawyers when choosing it? (Debian-legal comes to mind.)
Do you use anything besides SDL? Like OpenAL or SDL_sound, SDL_image and the likes?
Do you host on an own server or on some community service, like SF, BerliOS or Gna?
I hope you don't want to support MSVC? (Have bad experiences with that in my other project, Warzone 2100. Mostly prevents you from using any C99 feature.)
I got the idea to port JA2 to SDL, because v113 runs really crappy on Linux/Wine. I blame Fmod for most of this.
At the same time there seem to be interesting modifications to it, like an afaik easier data format. Did you try to port that? (expat is as-is, so should be compatible.)
What license are the v113 modifications under?
And, because I just read it in your faq: Why TF do the Windows folks want to port JA2 to DX9??? Or even D3D... Seems pretty crappy to me, and is also locking users with older PCs out.

Licence is really aims at profit of the SFI.
Dynamicly linked libraries is a rule. I don't want bigger executable size.

Obviously, my modifications (and modifications of my project mates) belongs to SFI (due to paragraph 5). But I prefer to release my code under GLP or LGPL base. I didn't took any lawer assistance, I was simply in passion from source control and participate in mod develpment.

I am using SDL, SDL_Config, fmod and expat. In plans - SDL_image, but current game architecture prevents to this. Probably, I'll replace fmod with SDL_mixer and SDL sound facilities.

Currently, I do not take steps towards win portability. At least, I do not write code for it.

Already ported. SDL and expat is in use. About to release alpha release. Didn't choose licence for my code yet.

I think, people want to test his strenght at coding. Thus there is DX9 with support of playing media. And even crazy D3D things. But I personally would prefer OGRE (or something like this), as a 3D engine for ja2.

This sounds to me that you may very well choose a license for your code/modifications (or even the entire sourcecode?) and that it does not belong to Strategy First (SFI?). Eg. the GPL would be more restrictive (in opposite to "broader") and still grant SFI the rights they want.
I will, however, ask some people who know better than I do about this.

Hm... really awful. Thanks for clearing licencing side of this question.
And providing diffs by current moment is extremely hard:
1. svn repository didn't started from vanilla source, but somewhere after long time of development.
2. my port was forked from 1.13, and soon after this, I renamed most of the files.
And now I have no idea, how to track all this changes and how diff will behave on such material.

You are not one of the stracciatella guys then? Since their binary doesn't seem to link against fmod nor expat or for that matter anything besides libsdl.
Stracciatella project aim is to bring _vanilla_ ja2 (as the first stage) to any platform, where sdl and gcc can be run. So, as it is vanilla, it doesn't have xml-files, nor ogg playback. Expat and fmod were result of legacy windows code. Expat was using even before I came to team. I simply had no choice here. But I am responsible for fmod appearing in ja2 1.13, because I rewrote sound manager for this library. It was my first serious code changes.

I was wondering about this line in the license,
"Commercial purposes include, but are not limited to, running a business, licensing, renting, or selling the Software, distributing the Software for use with any commercial products"
I was thinking of attempting to do a port of the game to the psp. Would such a thing violate the license in any way?
