Since the coop update, the Ancient key (which is always the reward for defeating the boss) would disappear when leaving the cave, making it impossible to open the locked door behind the Ancient Cave entrance counter. While this is basically cosmetic and has no adverse effects on the multiworld (as the door does not lead to any multiworld locations and is only accessible after defeating the final boss anyway), players may still want to enter this room as part of a ritual to celebrate their victory. Why does this happen? The game keeps track of two different inventories, one for outside and another one for the cave dive. When entering or leaving the cave, important things such as blue chest items and Iris treasures are automatically copied to the other inventory. However, it turns out that the Ancient key doesn't participate in this mechanism. Instead, the script that runs when exiting the cave checks whether event flag 0xC3 is set, and if it is on, it calls a script action that adds the key item to the outside inventory. (Whether or not the player actually had the key item in their in-cave inventory is not checked at all; only the flag matters.) In the unmodified game, that flag is set by the cutscene script that awards the key. It actually sets two event flags, 0xC3 and 0xD1. The latter is used by the game when trying to display the boss in the cafe basement and is used by AP as the indicator that the boss goal was completed. With the coop update, the event script method that created the key was intercepted and modified to send out a location check instead. That location always has the Ancient key as a fixed item placement; the benefit of handling it as a remote item is that in this way the key essentially serves as a signal that transmits the information of the boss' defeat to all clients cooping on the slot. When receiving the key, however, the custom ASM did only set flag 0xD1. As part of the bugfix, it is now changed to set flag 0xC3 as well. But that alone is still not enough to make it work. The subroutine that is called by the game to create the key when exiting the cave with flag 0xC3 is the same subroutine that gets called in the cutscene that originally tried to award the key. But that's the one that has been rewritten to send the location check instead. So instead of creating the key when leaving the cave, it would just send the same location check again, effectively doing nothing. Therefore, the other part of the bugfix is to only intercept this subroutine if the player is currently on the Ancient Cave Final Floor (where the cutscene takes place), thus making it possible to recreate the key item when exiting. |

History
Archipelago is built upon a strong legacy of brilliant hobbyists. We want to honor that legacy by showing it here. The repositories which Archipelago is built upon, inspired by, or otherwise owes its gratitude to are:
- bonta0's MultiWorld
- AmazingAmpharos' Entrance Randomizer
- VT Web Randomizer
- Dessyreqt's alttprandomizer
- Zarby89's and sosuke3's contributions to Enemizer, which make the vast majority of Enemizer contributions.
We recognize that there is a strong community of incredibly smart people that have come before us and helped pave the path. Just because one person's name may be in a repository title does not mean that only one person made that project happen. We can't hope to perfectly cover every single contribution that lead up to Archipelago but we hope to honor them fairly.
Path to the Archipelago
Archipelago was directly forked from bonta0's multiworld_31 branch of ALttPEntranceRandomizer (this project has a long legacy of its own, please check it out linked above) on January 12, 2020. The repository was then named to MultiWorld-Utilities to better encompass its intended function. As Archipelago matured, then known as "Berserker's MultiWorld" by some, we found it necessary to transform our repository into a root level repository (as opposed to a 'forked repo') and change the name (which came later) to better reflect our project.
Running Archipelago
For most people all you need to do is head over to the releases page then download and run the appropriate installer. The installers function on Windows only.
If you are running Archipelago from a non-Windows system then the likely scenario is that you are comfortable running source code directly. Please see our doc on running Archipelago from source.
Related Repositories
This project makes use of multiple other projects. We wouldn't be here without these other repositories and the contributions of their developers, past and present.
