ACK!MUD 4.1 - Historical Merc-Derived Codebase

About this resource

Historical ACK!MUD 4.1 source and world distribution, preserving its original NPC programs, runtime records and build files.

License and attribution
Source headers require compliance with the Diku and Merc licenses and preservation of their notices. No separately named full license documents were found in this archive. The collection's disclaim.txt also references inherited terms and ACK credits. Licensing evidence remains incomplete; do not infer distribution permission from archive availability.

Compatibility and security warnings
Includes player records, privileged test accounts, backups and runtime data. A separate privacy/security hold is required. Historical documentation describes unfinished features and incomplete help. Modern compiler and operating-system compatibility are unverified. Do not run with bundled accounts or assume security clearance.

A download checksum confirms file integrity, not security or runtime compatibility. Review the source and included documentation before running unfamiliar software.

Attribution stays with the work.
