The Dreamcast Dump Database


Welcome to Dumpcast--the Sega Dreamcast GD-ROM dump database.

The Dumpcast project was founded in 2007 by darc and az_bont as a project to catalog and preserve all published Dreamcast GD-ROMs. At the time, all Dreamcast emulator users played games on their PCs with hacked MIL-CD versions of games. Dumpcast members began dumping and cataloging GD-ROMs, and soon the GDI format was established by Raziel's nullDC emulator. After ackmed released the highly reliable httpd-ack GD-ROM dumping software, Dumpcast merged its efforts into the much larger TOSEC ISO project. Maddog is currently the maintainer of the Dreamcast branch of TOSEC ISO. Currently, the project has verified over 1,200 GD-ROM dumps, encompassing the entire North American and European game library, as well as much of the Japanese library.

In more recent years, optical drive emulator devices have been created, which allow users to replace their GD-ROM drive with SD card or USB connectors. These devices allow the playback of full GD-ROM dumps on original Dreamcast hardware.

To understand more on the importance of this project, read about the Dreamcast and GD-ROMs.

All of the Dumpcast action takes place on our forum!
