Multiworld Roadmap

Multiworld is functional.

Uses Archipelago ("AP") for multi-game multiworld generation and synchronization
See black-sliver / Archipelago / soe for seed generation
See black-sliver / pyevermizer for the interface to Archipelago
See black-sliver / apbpatch for ROM patching
See black-sliver / ap-soeclient for AP client

Below are the items that are still to be done.

Additional features for AP

  • Traps (items)

  • Death link (similar to items)

  • Copy seed/slot from ROM to RAM

  • Ingredienizer in AP to put alchemy in logic

  • Show remote player and/or item name

Semi-related features

  • Add memory block to signal which call bead spells have been viewed by the player
    (NOTE: if the player never opened the CB menu, the spells should not show up in the tracker)

  • Reserve space for Extended market timer

  • Reserve space for Energy Core fragments (unused trade good?)

  • Add magic number + version + seed settings to ROM

  • Copy magic number + version + seed settings from ROM to RAM (for RA+Snes9x)

  • Add flag "--hide-settings" that gets written to ROM so the tracker does not spoil (Mystery seed)

Steps

ROM generation

Status: PARTIAL

  • place ID sequence in ROM: done
  • memcpy ID sequence to RAM: TODO
  • use placement.txt for item placement: done
  • see other changes below: TODO

Reserve/assign memory

Status: PARTIAL

see wiki/Memory-Layout#ram-layout

  • Alchemy spots: 1bit per spell, so we can map 1:1; this needs to be bit-accessible by scripts done
  • Call bead visibility; this will be written by ASM code TODO
    • FIXME: for chaos the tracker will still have to read mapping from ROM
    • 4x4 bits: full enum for each slot -> tracker only reads these 2B
      • Unknown
      • FE
      • Horace
      • Horace + Aura
      • Horace + Regenerate
      • Horace + Aura + Regenerate
      • Queen
      • Prof.
  • Extended market timer: 1-2 additional bytes for the upper part RESERVED
  • Energy core fragments (maybe the 1 unused word in trade goods) RESERVED
  • 16bit integer for "last received item sequence number" done
  • Some bytes for multiworld communication done

Change item and location definition

Status: UNCERTAIN

  • Move boss locations, drops and addresses to `bosses.json?
  • Add utilities `bosses2h.py?
  • Same for alchemy?

Change how "unrandom" works

Stauts: TODO

At the moment if something is not randomized, it is not touched. Instead we should always apply the same modifications, but have the values fixed, to allow more options without making the code unreadable.

Call bead changes for the tracker

Status: TODO

Implement setting above bits when opening the corresponding ring menu.

Clean up and fix non-AP generation

Status: TODO

  • Remove old patches

Add remote player/item names

Status: TODO

In a future version we may want to display who sent or received an item.
