Metroid: Zero Mission Map Completion Notes

GENERAL NOTES
-------------
-Items: All majors, 4 energy tanks, 40 missiles, 8 super missiles, 12 power bombs (36%)
-Far from perfect, wanted to showcase some researched strats and find a more optimal ammo loadout
-I did not manipulate enemy/boss patterns, only drops
-You can do only 3 energy tanks before Tourian (need 215 energy minimum to survive all the heated rooms) but you are beholden to drops between the Ridley fight and caterpillars; one less e-tank would also make 2-hit early PBs required if doing gate clip
-Could maybe skip 1 missile tank (guarantees farm required before Acid Worm, already a decent possibility with this loadout)
-Zeb skip with Wave Beam sucks
-Late Acid Worm might be viable but drop luck becomes even more important in cleanup, not sure if faster
-Any and all door bonks intended to induce rage
-Let me know if there's anything big I missed or maybe didn't consider

TIMINGS/STRATS
--------------
-Bottom of Ridley pipe room Strats (skipping missile)
--Running across is slowest
--Shinesparking across is faster than running by ~24f
--Ballsparking across is faster than running by ~56f

-Speedway -> Right shaft Strats (skipping e-tank)
--Running across is slowest
--Shinesparking across is faster than running by ~16f
--Ballsparking across is faster than running by ~28f
--Safety: Grabbing the e-tank is 206f slower than ballsparking

-Imago
--Seems to crash into the brush after a set duration following death, grabbing its map tiles right after it dies is faster than grabbing them after getting the supers

-Imago to Elevator Strats
--Shinesparking from save room to elevator room (w/o crash/bonks) loses ~34f

-Heated Rooms Damage Taken:
--Below Screw: 60 HP
--Double Missile: 110 HP
--Wave Tutorial: 44 HP

-Gold Shaft to Tourian Strats
--Walljumping up is slower than a vertical spark by ~22 frames

-Brinstar Sidehopper Room
--Sparking to the right is faster than not sparking by ~28 frames

-Ruins Entrance Tile Strats
--8f faster to go get top-left tile by going landing -> top platforms, rather than grabbing the tile -> middle platforms.
--~50f faster to grab the tiles going bottom to top than top to bottom (in large part due to lag)

-Big Atomics Room Strats
--Normal movement (L to R): 472f (bad atomic RNG)
--Early Cleanup (L to R): 484f
--Late Cleanup (R to L): 473f
--Late Cleanup can save ~11 + (~20)f = 32f on early cleanup due to being able to run on the ground more (probably?)

-Wrecked Ship Bomb Chain Maze Strats
--Going through the maze is fastest
--Getting top-right tile and bailing right is slowest (+78 frames)
--Getting top-right tile and bailing left is less slow (+28 frames)

-Crateria Entrance to Landing Site
--MingLee: ~1471f
--No MingLee, Sparkless Ocean: ~1586f (+115 frames)

-Landing Site, Early vs. Late PB Tiles
--Escape time difference:
---(Late) Landing Site w/o PB tiles: 250f
---(Early) Landing Site w/ PB tiles: 502f (+252f)
--Cleanup difference (up to Tourian elevator entrance):
---Late 1718f / Early 1722f
-Similar enough to consider them equivalent IMO

-HJB Hint
--Getting the tiles late provides more opportunities to farm for PBs (if not refilling)

-Acid Falls
--Soft morphing on the floor and going right is about 14f slower than using the platforms

-Norfair East Big Room
--Space Boost saves ~88 frames

-Crateria Spaceboost
--If you skipped MingLee (+115f), you don't have to lay a PB to do the spaceboost (-87f over laying a PB after going up the elevator, putting you at ~28f lost)
--Not doing Crateria spaceboost loses ~228f

-Alpha PBs top tile
--Better to get on the way out to reduce lag

-PB management
--Chart: https://i.imgur.com/2KrA8z1.png
--Never PB going into HJB room from the back
--Never PB in the room before alpha PBs
--Best case you can skip 2 PB tanks, worst case you skip none and lose 5 additional seconds (see chart)

TIME COSTS TO GRAB PB TANKS
---------------------------
-Lava PBs:
--Grab: 879f / Skip 723f (+156f)
-Crateria Connector PBs:
--Grab: 629f / Skip 415f (+214f)
-Glass Tube PBs
--Grab 884f / Skip 708f (+176f)
-Ootw PBs
--Grab 1056f / Skip 824f (+232f)
-Beta PBs
--Grab 513f / Skip 304f (+209f)
