The Legend of Zelda: Ocarina of Time

7 projects let you play The Legend of Zelda: Ocarina of Time together. Here's how they compare, and which one to start with.

B
Recommended

Anchor (built into Ship of Harkinian) by HarbourMasters

Rated B like Zelda64 Online (Ocarina of Time Online), but further along: playable, against partial. It has partial story sync, shared items, easy joining with no port forwarding and open source code.

About this project

Merged upstream on 2025-11-14 (PR 4910), not January 2026 as in the seed; packets cover player updates, item gives, flag set/unset, dungeon items and teleports, and the OOT-True-Co-op README says enemies are not shared by Anchor. Default public relay anchor.hm64.org:43383 or self-host; open Anchor sync bugs exist on the Shipwright issue tracker.

About this project

Shares items and quest progress, keys, and some in-world entities; press coverage cites up to 15 players on a server and one review says rupees and health are not shared. Last release 3.0.72 was 2022-07 and a 2024 Reddit thread asks whether ModLoader64 is dead; the seed name Zelda64 Online is the repo name, not a separate project.

About this project

Multiworld randomizer link, so items found in one game are sent to other players' games; it does not put players in a shared world. An Android port bundles the same client.

About this project

Adds shared enemies and bosses on top of Anchor (one instance is the authority and runs enemy AI, the other mirrors it); README lists milestones M1 to M3 working, Gohma fully co-op, and known gaps such as Floormasters and enemy sound effects. Repo shows no license and is also built for two game windows on one PC with separate controllers.

About this project

README calls it a host-authority co-op prototype that streams enemy state and kills from the host, validates client hits on the host, syncs time of day, and has an optional item exchange mode. Examples show a host and one client; no releases and 3 stars at check time. Connects through the public Anchor relay by default (anchor.hm64.org:43383 in soh/soh/Network/Anchor/Anchor.cpp). Continued in ocarina-coop.
