Copper I - Historical DikuMUD Source and Library
Early Copper MUD source and companion world library, preserved as historical DikuMUD material. Requires security, compatibility, and licensing review before use.
About this resource
This historical Copper I release is split into Copper-src.tar.gz and Copper-lib.tar.gz. The source archive contains C source, headers, and a Makefile. The companion library contains world, mobile, object, shop, and reset data alongside help, credits, and runtime files. Obtain both components when studying the original distribution; this is not a modern ready-to-run package. Mudhaven has not compiled or boot-tested it. Archive provenance Both original source and library archives are staged on-site for private staff review; both components are needed. Copper-src.tar.gz Copper-lib.tar.gz Preserved in Internet Archive's MUD collection APR 2024. These are archived copies, not a current official release site. Each linked archive was downloaded and its SHA-256 checksum matched against the reviewed local original on October 18, 2026. Security and completeness warning The reviewed library contains a nonempty players file and an account-data file. Review historical runtime data privately before use or redistribution; do not deploy inherited accounts or credentials. Audit the old networking and authentication code before exposing a server. License warning The code references the original DikuMUD license. Its text is embedded under DOC_LICENSE in the companion library's help_table; the source archive has no standalone license document. Read the complete original terms, preserve copyright and attribution notices, and review all contributor material. Do not assume the later DikuMUD LGPL announcement automatically relicenses Copper. This listing and private staging grant no reuse or redistribution rights.
Compatibility
Historical Unix C code; needs porting and security review. Not compiled or boot-tested by Mudhaven.
A download checksum confirms file integrity, not security or runtime compatibility. Review the source and included documentation before running unfamiliar software.
