Known Prefixes


NetHack uses the prefix "NHDT" internally to identify specific information (such as versions and dates) produced by the NetHack Development Team. NetHack variants should use a different prefix. This page lists the prefixes we know about.

We encourage projects to register to prevent confusion. To register, send an email to devteam@nethack.org with the prefix you wish to register, contact information for the project (email or URL), and the project's name.
