Archipelago Multiworld Framework

Archipelago is a generic framework for developing multiworld capability for game randomizers. In its current implementation, Archipelago also functions as the randomizer itself. It supports a wide variety of games, including:

• The Legend of Zelda (various titles: A Link to the Past, Ocarina of Time, Wind Waker, Link's Awakening DX, etc.)
• Factorio
• Subnautica
• Risk of Rain 2
• Super Metroid
• Hollow Knight
• Stardew Valley
• Terraria
• ...and many others (see full list in repository).

For detailed setup and instructions for specific games, visit the tutorials page.

MSU-1 is a technology that allows for custom in-game music. It is compatible with original hardware, SuperNT, and certain emulators like Snes9x.

To use custom music, you need to acquire MSU packs. You can find a list of completed and in-development packs in this Google Spreadsheet.

The Pokémon Emerald randomizer handles both item and Pokémon randomization.

Randomized Elements:

• Items: Badges, HMs, gifts from NPCs, and items found on the ground. Key items (e.g., Devon Scope, Mach Bike), Potions, Revives, and TMs can also be randomized.
• Pokémon: Wild Pokémon, starters, opponent Pokémon, abilities, and types.
• Battle Mechanics: You can configure a percentage of single battles to be converted into double battles.

For a full list of configurable options, refer to the player-options page.

The worlds/alttp/enemizer_data/ directory contains vendored and generated modules derived from the upstream Ijwu/Enemizer project (Release family 7.1). These modules provide the underlying data structures and metadata required for Enemizer-based randomizations in the ALTT P world.

Key data modules include:

• base_patch_data.py: The base patch applied by Enemizer before feature-specific randomization.
• symbols.py: The assembled symbol map used by Enemizer's runtime code for ROM addresses.
• enemy_room_metadata.py & overworld_enemy_metadata.py: Constraints for room and area grouping/randomization.
• enemy_sprite_requirements.py: Sprite metadata for the native enemy shuffle implementation.
• dungeon_sprite_addresses.py: Dungeon sprite slot metadata keyed by enemy addresses.
• pot_shuffle_data.py: Room and item source data for the native pot shuffle.

The Archipelago version of Muse Dash includes several modifications to the base game:

• Song Select Filters: New filters are available to help find songs easily.
• Random Selection: Selecting 'Random' during a seed will pick a song you have not yet finished.
• Master Difficulties: These are always unlocked during a seed.
• Hints: Hints are displayed when viewing a song in the song select menu. You can also request hints for specific songs or music sheets directly from the song select menu.

The randomizer includes several modifications to improve the gameplay experience:

• Exploration: Shoal Cave switches between high tide and low tide on every re-entry. You can run or bike (almost) anywhere, and you can use both bikes simultaneously.
• Inventory: Bag space is greatly expanded to minimize PC storage needs.
• Evolution: Trade evolutions are replaced with level or item evolutions.
• UI/UX: The Wally catching tutorial is skipped. All text is instant and can be automatically progressed by holding A (optional). When a Repel runs out, you are prompted to use another.
