Jako: /* General Route */

True Completion can mostly be distilled into a mixture of [[100%]], [[100% Map Completion|Map Completion]], and [[All Chozo Hints RTA]].

In True Completion you must do the following:
* Acquire 100% items
* Visit all map tiles
* Visit and activate all map stations
* Open all non-blue doors at least once
* View the boss statues after Long Beam
* Visit and [[All Chozo Hints RTA|activate all standing Chozo statues]]
* Varia Suit must be obtained from the statue in Brinstar
* Defeat Kraid before Ridley
* Destroy all 4 Zebetites

The category is based doing everything you can do in the game that sets permanent flags in memory (outside of destroying all non-reappearing blocks) in addition to grabbing all the map tiles.

Some of these requirements are a little redundant, as in both 100% and Map Completion, you fight Kraid before Ridley (and view the cutscene upon leaving Kraid), and with the ammunition you have in 100%, you destroy all 4 zebetites rather than skipping them.

=Prerequisites=
* [[General_Movement#Infinite_Bomb_Jumping_.28IBJ.29|Infinite Bomb Jumps]]

=General Route=

This is the first draft route, the run is ~85-90 minutes. Subject to change.

1. Long Beam -> Bombs hint -> Bombs -> Ice beam hint -> Brinstar map -> Wave Beam hint (skip Early Brinstar items) -> Norfair

2. Power Grip -> Ice Beam -> Speed Booster hint -> Varia Suit hint -> Kraid

3. Kraid identical to [[100% Map Completion|Map Completion]] -> Hi-Jump hint -> Norfair

4. Norfair -> Ridley identical to Map Completion but ignore the Ice Beam section/upper heated room

5. Ridley identical to Map Completion but with early Imago (don't forget the save room by the elevator).

6. Open Ice Beam green door after escaping from Ridley & grab the heated room missile/tiles above

7. Grab Varia Suit/upper Brinstar items & tiles immediately after Brinstar Super and head to Tourian

8. Cleanup identical to Map Completion

Two quirks of this category compared to 100% or Map Completion:
* You have Power Grip on your first trek through Kraid
* Your first Super Missiles are at Imago

=Missable Doors=
[[File:missableDoors.png | 752px]]

These are the doors that are possible to miss in a route where you pick up 100% items and map tiles.

In Tourian you will want an extra Super for Tourian escape to open the green door, since internally the door is separate from the one seen in cleanup.

=Drop Rates=

Adapted from Dragonfangs' guide on SRC: https://www.speedrun.com/mzm/guide/dir80

'''Practical stuff'''

The game does a couple of calculations based on the enemy's position, its index in RAM and multiple RNG values to get a number between 1 and 1024 (the calculation is explained in the "Technical Mumbo Jumbo" part if you're actually interested). Controlling this number in any meaningful way is not reasonable in real time, for all practical reasons it is truly random.

This number is then tested against the raw drop rates derived from the table above. To get the raw value, multiply the number in the table by 1024.

If it's bigger than 1024-(rate for power bombs) you get a power bomb drop, otherwise if it's bigger than 1024-(pb rate)-(super rate) you get a super and so on, continuing with Missiles, Large health and Small health. After your drop is decided however, it can transform into something else based on your current resources.

For health(big and small) it does the following checks:

If health is not full: drop normally
otherwise, if missiles are not full: drop a missile
if both health and missiles are full: drop normally anyway

For everything else, it does the following:

Is the resources in question not full: drop normally
otherwise, if health is not full: drop a large health
otherwise, as long as you have the item unlocked: drop normally anyway
or finally, failing everything else: drop a small health

So when looking at the drop tables, you can (in cases that matter) add both health drop rates to missile drop rate if you're full on health. And if anything else is maxed out, add it to large health drop rate.

'''Technical Mumbo Jumbo'''

The game uses two RAM values for the RNG calculation: 0x3000C77 and 0x3000002. I will refer to them as "frame1" and "frame2" respectively in the formula. These change every frame but can also change by invoking random elements (like checking for drops).

The formula starts as follows (% denotes a modulo operation):

((frame1 + 1) % 256 + ((frame2 + 1)/16) + (enemy's index in the list of enemies) + (enemy x position) + (enemy y position)) % 32

the result will then be used as an index to fetch a number from this list, I'll refer to the fetched number as "listRNG":
{13, 2, 6, 8, 7, 9, 14, 10, 2, 4, 14, 4, 12, 15, 13, 12, 11, 1, 3, 15, 0, 6, 7, 8, 11, 5, 0, 3, 5, 1, 9, 10}

the calculation continues:

((frame1 + 1) % 256 + (frame2 + 1) + listRNG¤256) % 1024

and the resulting number is compared against the drop rates.

Note that metroids, in order to give two drops, are technically two enemies, with the second one dying at the same time and in the same location as the first one. So the only thing different between the two drops is the enemy index.

List of Enemies

Jako:

Enemies do 2x damage in Hard mode, and 0.5x (rounded down) on Easy mode.

Varia Suit reduces damage by 20% (rounded down) and Gravity Suit reduces damage by 50% (rounded down).

=Drop Rates=

Adapted from Dragonfangs' guide on SRC: https://www.speedrun.com/mzm/guide/dir80

'''Practical stuff'''

The game does a couple of calculations based on the enemy's position, its index in RAM and multiple RNG values to get a number between 1 and 1024 (the calculation is explained in the "Technical Mumbo Jumbo" part if you're actually interested). Controlling this number in any meaningful way is not reasonable in real time, for all practical reasons it is truly random.

This number is then tested against the raw drop rates derived from the table above. To get the raw value, multiply the number in the table by 1024.

If it's bigger than 1024-(rate for power bombs) you get a power bomb drop, otherwise if it's bigger than 1024-(pb rate)-(super rate) you get a super and so on, continuing with Missiles, Large health and Small health. After your drop is decided however, it can transform into something else based on your current resources.

For health(big and small) it does the following checks:

If health is not full: drop normally
otherwise, if missiles are not full: drop a missile
if both health and missiles are full: drop normally anyway

For everything else, it does the following:

Is the resources in question not full: drop normally
otherwise, if health is not full: drop a large health
otherwise, as long as you have the item unlocked: drop normally anyway
or finally, failing everything else: drop a small health

So when looking at the drop tables, you can (in cases that matter) add both health drop rates to missile drop rate if you're full on health. And if anything else is maxed out, add it to large health drop rate.

'''Technical Mumbo Jumbo'''

The game uses two RAM values for the RNG calculation: 0x3000C77 and 0x3000002. I will refer to them as "frame1" and "frame2" respectively in the formula. These change every frame but can also change by invoking random elements (like checking for drops).

The formula starts as follows (% denotes a modulo operation):

((frame1 + 1) % 256 + ((frame2 + 1)/16) + (enemy's index in the list of enemies) + (enemy x position) + (enemy y position)) % 32

the result will then be used as an index to fetch a number from this list, I'll refer to the fetched number as "listRNG":
{13, 2, 6, 8, 7, 9, 14, 10, 2, 4, 14, 4, 12, 15, 13, 12, 11, 1, 3, 15, 0, 6, 7, 8, 11, 5, 0, 3, 5, 1, 9, 10}

the calculation continues:

((frame1 + 1) % 256 + (frame2 + 1) + listRNG¤256) % 1024

and the resulting number is compared against the drop rates.

Note that metroids, in order to give two drops, are technically two enemies, with the second one dying at the same time and in the same location as the first one. So the only thing different between the two drops is the enemy index.

'''Welcome to the Zero Mission Speedrunning Wiki!'''

Metroid: Zero Mission is a remake of the classic Metroid videogame for the NES, except this time it's updated for the Gameboy Advance with all new physics, graphics, items, and an entire new postgame section. The speedruns for Zero Mission focus heavily on platforming movement, with some stylish tricks sprinkled throughout each category.
