Welcome to the Dreamcast Vault. This Vault will soon contain a perfect copy of every Dreamcast game released in the US, verified by Redump. To play them you'll need an emulator from the Emulation Lair.
Construction of the Dreamcast Vault is on hold while Redump completes their US catalog. For now all discs are in .gdi format.
All games are in .7z format and can be opened with the free tool 7-Zip.
