Hidden Palace has been a monumental icon when it comes to preserving the history of Sonic the Hedgehog prototypes and beta cartridges. They've got more to offer than just that, though, with their latest work being something called Project Deluge. Containing a little more than 750 different PlayStation 2 prototypes, betas, and working builds of games, Project Deluge is the team's effort to preserve all these little pieces of gaming history by dumping each and every disc they've found. Some of the contents of their collection include prototypes, E3 builds, and demos of Metal Gear Solid 2, Shadow of the Colossus, Okami, and many, many, many more. A full, detailed list is being worked on by Hidden Palace and users on The Cutting Room Floor to document any significant differences in these betas, and is available to read, here.

Sorry I’m kind slow what’s the difference between the prototype they release and the ps2 Iso we already have ?

From what I've seen these are review copies or trade show demo disks. Most likely the interesting stuff could be:

1)Inaccessible stuff on the trade demos
2)Extra content hiding on the discs that were removed in the final releases (leftover data from earlier versions or cut areas/levels/music)

But...

Does it contain a version of Duke nukem forever that's actually good?

Does such a thing exist?

Does such a thing exist?

Hence the question.

Serious answer: DN forever apparently went through quite some many phases, often in near finished state...then to be remade with a new engine and/or design philosophies. Without joking or sarcasm: it's quite possible there's a (of course much smaller) version out there that's simply more in tune with the older DN3, and as such could be literally better than the end product.

If it's the source code of the prototypes, that's actually useful. That means any PC could play without an emulator, as long as it's compiled. Alternatively, the games could be recompiled for any contemporary system.

There was no source code released unfortunately, these are preview/sample discs sent to gaming magazines for the most part.

Earlier versions of games which may or may not have interesting differences or debug features compared to the retail releases.
