Source catalog Release Mod 1.2.3 / APWorld 1.2.2Cobalt Core APWorld 1.2.2

This catalog lists 845 addressable candidate names from the APWorld address table after excluding nine ship/character rows that the World does not register as checks. It contains up to 461 card slots, 360 artifact slots and 24 memory timeline slots. Card and artifact totals vary with options and balancing; shuffled memories become network checks, while unshuffled memories are local events. The Future Memory completion event has no address and is not included. Static source review only; no game session was run.

Actions and milestones that can send a check to your multiworld.

Playing with others

Separate solo campaigns exchange rewards through Archipelago; this is not native shared-ship co-op. Optional in-game DeathLink is off by default and can cause a missing-crew effect, fixed or percentage hull damage, or death. Received effects apply during a run, not while outside one. Reconnect the same AP save for later sessions.

Known scope and limitations

  • Use client 1.2.3 with APWorld 1.2.2. The client checks the World slot-data version; its own 1.2.3 version number does not mean an APWorld 1.2.3 is required. Existing 1.2.2 rooms are supported by the release.
  • The documented stack is Cobalt Core 1.2.9, Nickel 1.20.3 or later and Archipelago 0.6.6. Install the mod through Nickel and the World in Archipelago; generating a YAML alone does not install the client.
  • Use an Archipelago profile and keep separate backups of the game save and Nickel mod storage. Vanilla save import is not supported. Restart the game when changing profiles or rooms.
  • The connection form detects a different seed but allows an override, and saved room identity does not include the AP team and slot. Do not reuse a profile for a different slot or force a room mismatch.
  • Mod storage includes the room password in plain JSON. Keep that file private. Use an explicit wss:// server address when supported; scheme-less addresses can fall back to unencrypted WebSocket.
  • Modifiers received during an active run can miss their future-run unlock when the immediate-effect branch rejects them, including unlockable-only mode. If a modifier is missing, reconnect from the menu and inspect the unlock before continuing.
  • Checked locations already stored locally are resent on reconnect. Queued combat rewards are recorded before their effects execute, however, and the item ledger is separate from the game save. Avoid switching rooms with pending rewards and retain backups before replacing files.
  • Keep the connection active for the final memory or Future Memory ending and confirm victory on the AP server. The reviewed client sends victory directly without a durable retry marker.
  • Difficulty logic estimates access from crew and card/artifact counts; it cannot guarantee success in a particular combat run. Custom Run Options is required when generating fewer than three starting characters.
  • The source declares licences, but the client archive omits licence notices and separate permissions for game-derived material are not fully documented. This is a documentation gap, not a finding of unlawful distribution.
