About this resource

Historical ACK!MUD 4.3 source, world and documentation package with original license documents, NPC data and platform build scripts.

License and attribution
Includes Merc, DikuMUD and ACK terms in docs/license.txt, docs/licensediku.txt and docs/acklicense.txt. ACK-specific copying and modification wording is conditional on applicable inherited licenses, preserved copyright notices and required greeting/help credits. Retain every bundled license unchanged. Public release still requires separate licensing review.

Compatibility and security warnings
Includes player records and privileged test accounts. A separate privacy/security hold is required. Contains historical RTF documentation and Unix/BSD/Windows build and startup files. Modern compatibility and security are unverified. No software was executed or declared malware-free.

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.
