A few years ago, I found a Doom Dreamcast prototype source code in a Katana dev kit. Built with Windows CE in 2000 and using DC peripherals like the VMU, it was created as a programming exercise. Try it below:

Do you know why SEGA decided to close No Cliché rather than sell the studio?
Because SEGA wanted to retain the intellectual property rights to Toy Commander. By selling it, SEGA would have had to sell the IP.

Unreleased games that were never announced or never found a publisher are often the most fascinating. They frequently feature original concepts or unique art direction. Sadly, they draw little attention, since most people only look for big names like Soul Reaver 2 on Dreamcast

Do you remember Stunt Driver PC. The game that included a track editor?
A version of that 1990 Hit was running on the first Xbox as a kind of tech demo. I believe the graphics were improved. It was a programmer’s practice project, a exercise to get familiar with the hardware.

Half-Life Dreamcast isn’t the only known official prototype on CD-R. Agartha and Chakan for Dreamcast also exist on CD-Rs. Without being able to state it explicitly, one studio reportedly used CD-Rs for beta testing their games to avoid dealing with the Disc System 2 and the red GD-Rs!

Looking Glass Studios was in talks with SEGA to develop a new Shinobi game for the Dreamcast before the Overworks version that was ultimately released on the PS2. The American studio had a story, some artwork, and a rendered intro video (but no playable build).

I’m able, though not 100% certain yet, to say that we’ve given incorrect build dates for all the known Geist Force Dreamcast prototypes. Everything would need to be redone from scratch for this game, but it’s impossible to rely on file modification dates or the IP.BIN to date them.
