Sega Dreamcast: Collected Works, an upcoming book from Read-Only Memory, is the followup to SEGA Mega Drive/Genesis: Collected Works. Successfully backed on Kickstarter late last year, Read-Only Memory sent a new years update to backers and boy is it an exciting one! Read-Only Memory received a large amount of production materials from SEGA of Japan, including several never-before-seen pieces from popular Dreamcast games. Included in the haul are:

Game mechanic sketches, environment concepts and high end renderings for Sonic Adventure

The complete design document for Jet Set Radio/Jet Grind Radio, including some amazing graffiti artwork concepts

A very early proof of concept video for Space Channel 5

Character studies and production artwork for Phantasy Star Online

Storyboards, character designs and environment artworks for Shenmue

Read-Only Memory will spend the coming weeks sorting through all the materials and identifying pieces to include in the book, with the final cut of the book to be laid out in a few months. Also revealed is that photoshoots for the Hardware Showcase chapter of the book will be taking place in the next few weeks, featuring everything from consoles to the fishing controller to the Samba de Amigo maracas. If you’re the proud owner of a Dreamcast hardware rarity you think should make the final cut, please do drop Read-Only Memory a line!

We here at SEGAbits can’t wait to get our hands on the book, and in the meantime we’re working to get Darren Wall of Read-Only Memory back for another Swingin’ Report Show podcast.
