The logic for Super Metroid Map Rando is based on the sm-json-data project. For details about how to interpret the JSON, see the documentation there. This page links to listings of strats by room and also by tech.
Work is still on-going on the logic. Some things to be aware of:
More strats and tech will be added over time. The goal is that any useful strats that are humanly viable should eventually be put into the logic.
A few of the tech, the ones not listed on the Generate page (e.g. canDisableEquipment), are currently ignored by the randomizer as they are implicitly assumed to be in logic on all settings.
The difficulty tier shown for a strat in these pages is based on the most favorable situation for executing it, e.g. assuming unlimited resources, items, cross-room runway length, and obstacles being already cleared. The randomizer logic takes into account such situational details: just because a strat is listed as "Basic" in these pages does not mean it will necessarily be in logic on "Basic" settings in every situation.
The tech pages only list strats that reference the tech directly or by a helper, but not by a dependency. For example, "canWalljump" does not list strats that require "canPreciseWalljump". This is to avoid cluttering the lower-level tech pages with strats that more properly belong to higher-level tech pages.
