About this resource

Historical ACK!MUD 4.2 source and world distribution, including NPC programs, build files and original runtime records.

License and attribution
Source headers reference the Diku and Merc licenses and require retaining notices. No separately named full license documents were found in this archive. Do not assume a later ACK release's license document resolves this version's missing documentation. Licensing review remains pending.

Compatibility and security warnings
Includes player records, privileged test accounts, backups and runtime data. A separate privacy/security hold is required. Historical C source and data formats require version-specific testing. Modern compiler, operating-system compatibility and security have not been verified.

Compatibility

Historical C source and world data. Modern compiler, operating-system and network compatibility unverified.

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.
