FrotzDC is an Interactive Fiction interpreter for the Sega Dreamcast which can play v1 through v5 Z-machine games. Several popular Z-Machine games include the Zork trilogy, Adventure, and The Hitchhiker's Guide to the Galaxy.

People that are new to Interactive Fiction should check out the Beginner's Guide to Interactive Fiction by Joe W Aultman and may wish to play several games online in their browser at iFiction. A great site to download freeware games for use with FrotzDC is The Interactive Fiction Archive.

FrotzDC is based on UNIX Frotz version 2.43, which is released under the GNU General Public License.


The latest version of FrotzDC has limited support for sound effects. In order to use sound you will need to convert your audio files to wav format and put them in a folder with the same name as the game. For example, for sherlo.z5, you would have a folder named "sherlo" to contain the files.


FrotzDC requires a font file on the root of the CD named hybrid.fnt. The original release includes a font that supports MS-DOS code page 437, which is available in this repo as cp437.fnt. A new font supporting latin1 was contribued by @hlabrand is available in this repo as latin1.fnt. Either file can be renamed to hybrid.fnt on the root of your Dreamcast CD-ROM depending on which character set is required for your Z-Machine game.
