Dreamcast prototypes (not only) available for download
GD-R is the name of the Dreamcast-format burnable discs (prototypes). This inscription is found on the left or right of these CDs (abbreviation of GIGABYTE DISC RECORDABLE). They are mainly orange. Some GD-Rs are blue with "Katana" written on them, which was the console's code name. The reading surface is blue, a good way to authenticate them. As they are not pressed, the risk of damage or rotting discs is higher than on manufactured commercial games.
Some steps in the development of a video game
Tech Demo: A simple presentation of the game to get an idea of the concept, a level or an environment for example.
Vectical Slice: A 10-minute slice of gameplay to demonstrate the title's potential. A VS is expensive to produce, around 100,000 E. A Vertical Slice is polished as if it were a final version. It will help to raise the necessary funding for further development of the game (finding a publisher).
Alpha: The game's first mount, with a progression in its development, making it playable most of the time, even in a basic way.
Beta: The content is complete, but the game needs to be optimized. This is the bug detection phase, the Beta Test.
Release Candidate: Once the Beta Test phase is over, the game must be submitted to the manufacturer for approval. Either it passes the test, or it goes back to correction. There may therefore be several Release Candidates, 1 then 2 or even 3, until the problems have been corrected. It's rare to reach this point, as the risk of having to postpone the game's launch is high.
Preview: We're on to something that really matters, and the differences with the final version are minimal. The developers are making final adjustments in preparation for the game's release. This version is intended to be shown to the public. In general, this is the Beta or a limited version of the Beta. This is what journalists use for game previews.
Review: We're practically on a final version, give or take a few details. It could be a Release Candidate. That's what journalists use to test games.
Final: The game as it will be found in stores.
This page references around 300 Dreamcast prototypes and a few from other consoles. There's everything from Previews and Reviews to Vertical Slice and Tech Demos. The most interesting prototypes have a page devoted to their analysis and the history of the game in question.

I have two different builds of Slave Zero having these dev options.
You can download them below:
Slave Zero (Aug 20, 1999 prototype)
Slave Zero (Nov 22, 1999 prototype)
The differences are few. This prototype is getting closer to a final version.
Gallery image (PVR) is incomplete.
Some boxes explaining the gallery's drawings are empty (character Alucard).
The end audio (ADX) contains noise.
The ADX end is not used in the US version, so it is meaningless.
