Notes: A multiworld randomizer world for Lufia II's Ancient Cave. worlds/lufia2ac/Options.py states vanilla values in its option documentation (final floor 99, party starting level 1, blue-chest chance 5/256, Iris-floor chance 5/256, 9 Iris treasures, Master HP 9980, the six chest-category chances); Items.py lists the blue-chest and Iris item ids; docs/en_Lufia II Ancient Cave.md describes the 99 floors, Providence and what persists. It reads and patches a ROM, so these are stated mechanics and leads, not a byte-level source.

The Ancient Cave has 99 floors, and the game builds each of the first 98 at random as the party reaches it; the 99th is a fixed map. Entering clears the floor count and arriving on the cave's map with a count of 0 sets it to 1; each floor is built with the count as its number and the count rises by one after it, and when the count stands at 99 the game loads the fixed map instead of building one.	`worlds/lufia2ac/docs/en_Lufia II Ancient Cave.md L11–14`	Code
Each Ancient Cave floor rolls the contents of its chests before it lays out its rooms: eight rolls of a byte from 0 to 255, one per chest. A roll of 174 or more gives a weapon, 129 to 173 a piece of armour, 99 to 128 a spell scroll for a spell none of the four party members knows (or else a restorative), 94 to 98 a blue chest, 36 to 93 a restorative, and 0 to 35 another consumable. Weapons, spells, blue chests and the other consumables are drawn evenly from their lists, and armour evenly from the first n mod 128 items of its list of n (lufia-ii/cave-armor-wrap); the restorative takes the average of two draws, so the middle of its list of nine comes up most. When an Iris treasure or Providence takes the first chest, the rolls fill the other seven.	`worlds/lufia2ac/Options.py L104–105`	Code
