zelda 2 randomizer notes

mutual notes:
	-the run is assumed to be glitchless
	-"disable magic container requirements" is assumed to be on (for now)
	-RAFT is always required for anything pertaining to east hyrule or maze island
	-BOOTS, HAMMER, or FLUTE may be additional requirements for reaching any given tile
	-M-KEY or FAIRY are always a possible requirement for completing palaces

===

GENERAL
-"include pbag caves in item shuffle" merely turns three "minor" item locations into "major" ones
	-i have not confirmed if the three pbag caves get shuffled anyway if they've been replaced with heart containers (see below)
-the amount of minor items in the major location pool depends on the ROM's starting conditions
	-every item you start with gets replaced with a pbag
	-7 major locations will have either a heart container or pbag depending on the difference between maximum and starting heart containers
	-most presets start you with the candle and 4/8 heart containers, meaning there will be 4 minor items in major locations
-"shuffle small items" has no effect on major item placement, but it means that any minor items in major locations won't always be pbags
-with the above rules in mind, it is possible for a major location to have a minor item but not vice versa. for example, a magic jar may be found in a palace's item room, but you will never find anything significant where a 1up or magic jar normally appears
-as far as i can tell, "palaces contain extra keys" merely forces every minor item location within palaces 1-6 to contain a key (at the expense of a pbag/1up/magic jar normally found there)

===

DISTRIBUTION
- north palace and great palace are not counted as palaces here
- the variance in palace count is based on whether "include great palace in shuffle" is enabled, which can swap the great palace across continents with any palace that contains an item
- the variance in item count is based on the above in addition to whether pbag caves are relevant, either due to "include pbag caves in item shuffle" being enabled or there being more than 4 heart containers to find

west hyrule:
	-BAGU is found in a forest tile
	4 towns
	7-9 items

	6-9 items
		2-3 palaces

PALACES
-as far as i know, palaces 3 and 6 cannot be distinguished from the first screen. they can also have the exact same room just beneath the entrance, so it may take a considerable time investment just to tell them apart
-the above only applies if "allow palaces to swap continents" is enabled. otherwise, the two palaces are quickly distinguished by whether they were found in west or east hyrule

west hyrule:
	Level 1:
		-identified by: totem pillars and no response from iron knuckle statue
		-has open windows
		-free of requirements

	Level 2:
		-identified by: dripper pillars
		-has "lattice" pattern windows
		-1 possible GLOVE wall
		-1 major death risk without FAIRY/JUMP

	Level 3:
		-identified by: blocky pillars
		-has "double cross" windows
		-2 possible GLOVE walls

maze island:
	Level 4:
		-identified by: totem pillars
		-has no windows
		-free of requirements

east hyrule:
	Level 5:
		-identified by: dripper pillars and no response from iron knuckle statue
		-has stained glass windows
		-free of requirements

	Level 6:
		-identified by: blocky pillars
		-has no windows
		-2 possible GLOVE walls
		-1 possible FAIRY wall
		-softlock risk without GLOVE

	Level 7:
