Browsing the duke4 forums, I realized that the community is trying to port Blood into eDuke32. Just want to shout out to you guys (SwissCM and co.), thanks and for the sake of Caleb and Ophelia, I hope you guys succeed! :)
(can't get used to Build engine anymore after the success of Doom ports and eDuke32)

Man I've always wondered why Blood couldn't run on eDuke. I always assumed it was because Blood source code was never released. I just hope they succeed! A workable port forwindows would solve everything! As long as it was as easy to use as McTecman's Blood loader!

Blood added quite a bit to the build engine, specifically with voxels

EDuke32 supports voxels. It's the gameplay features which are most dominantly hard to replicate, physics most notably.

The source code for Blood has not been released, like it has for DUke 3d and Shadow Warrior, which is why it is so hard to make it work in Eduke32. And this is why there is a campaign to get Atari to release the code for Blood.

Well if there is a campaign it isn't very organized. I think if some firm action were taken, and trust me I don't know what that means, maybe some sort of petition through GoG, there might be some movement on it. I kind of feel like Blood has changed hands so many times Atari might not even realize the source code hasn't been formally released. I can't think of a single reason for them NOT to release it. I mean has there even been an attempt to contact them on the issue?

I agree it has not been well organized. The usual On Line Petions..and we know how seriously they are taken.

The reason is because there's no reason for them TO release it.
The only reason we have the source for Doom/Duke/Shadow Warrior is because id and 3D realms are... er, was in id's case... independent companies run by the developers. John Carmack is the kind of guy to say "Hey, why don't we release the Doom source code just because?" I doubt the head of Atari feels the same way about their library of intellectual property.

I'm actually glad you brought that up because its part of my point on an FPS thread in the General Discussion board. The mentality of companies was different back then because dev teams were, as you rightly point out, small, tight knit, and practically independent. Even though I think Duke's source wasn't released until sometime after 2000. Still, in Doom's case you're right. I just think that the story would be different if we were asking for the source to some FPS game from say 2000. One with fully polygonal 3D graphics...one that was intended to run in windows. But we're not. We're asking for a source that is extremely outdated and would only be used to port a game that is only now being officially reissued. I can't see how that would backfire. If anything it would generate more interest in the game. Yes, its their intellectual property. But, in terms of gaming technology, its like high school clay models versus post college relief sculpture. I can't see where they lose.
