2002

Kraid Quick Kill - July 2002 (unclear)

Earliest reference found, attributed to player *mie*.

Adopted for runs in February 2004 by Red Scarlet and Smokey.

2003

Zebetite Skip - July 9, 2003

Player Pogo708 unknowingly skips the Zebetites. That event triggers further exploration of the glitch by deskjockey_, Ultima4701 and Kejardon.

At first, deskjockey_ stucks Samus in the Zebetite with a diagonal shinespark and Ultima4701 manages to finish the skip with Grapple (Speed+Grapple Zeb skip);

later, Ultima4701 finds a way to jump through the Zebetite without the need of Grapple (Speed Zeb skip);

at last, by understanding the mechanics of this Zeb skip, Kejardon develops the method of freezing a Rinka with Ice Beam and uses i-frames to get stuck inside the Zebetite (Ice Zeb skip).

Green Gate Glitch - September 24, 2003

Ultima4701 posts about MathOnNapkins discovering the green gate glitch:

"9/24/03 - All hail MathOnNapkins! A way beyond crucial green gates has been found! The ZMV is uploaded to the appropriate section."

2004

Phantoon First Route - 25 July 2004

Taser Frenom proposes and demonstrates that going to Wrecked Ship right after early game items collection is faster than going to Kraid's Lair. This becomes known as the "TAS route".

2005

March 6, 2005

Kejardon posts about discovering Spacetime-like effects from using X-Ray Scope in certain places Out of Bounds.

March 21, 2005

Arm pumping is discovered by michael flatley.

May 26, 2005

Kejardon posts about Illy discovering X-Ray Climbing.

2007

April 1, 2007

Kejardon (under a pseudonym, see page 2 of the thread) posts an SMV showing completing the game with 13% by X-Ray Climbing in Golden Four, then X-Ray Climbing in Mother Brain's Room to bypass the Mother Brain fight.

This run also came with this comment about another discovery in the game:

Finally, the trigger that makes Zebes explode is simply entering the room behind Mother Brain - all Mother Brain does is set the timer that kills you. It's a random tidbit of trivia I've only now had the chance to put to use.

2008

May 9, 2008

Hotarubi posts this video showing the springball strat used in Lower Norfair Spring Ball Maze Room for 100%.

JAM talks about the discovery of the GT Code here, in "Part 7": http://forum.metroidconstruction.com/index.php/topic,2319.msg28930.html?PHPSESSID=7692891baede64b1d76ead1656039c49#msg28930

The article that ensued: http://www.gamasutra.com/view/feature/196769/why_super_metroids_hacking_.php

2013

April 21, 2013

Cardweaver posts this video showing it's possible to do the Hi-Jumpless Lava Dive.

2014

March 5, 2014

Total posts on TASvideos about the investigations he's done into how Spacetime Beam works on a technical level, and posts that to the wiki.

March 7, 2014

Total and Lioran post this video showing a Spacetime Beam setup to trigger the escape sequence in the Pre-Moat Room (Crateria Kihunter Room). The next day they post this video, which is one of the most common setups used now for Any% GT Code.

March 10, 2014

amaurea posts a proof of concept TAS for Arbitrary Code Execution using Spacetime Beam.

2015

Spike Suit - 21 June 2015

EternisedDragon publishes a new method of obtaining a Shinespark Suit, using damage from spikes.

August 17, 2015

AxlSR discovers a variant of the shinespark strat that's currently used in Red Kihunter Shaft in modern runs of Any% PRKD.

September 11, 2015

Total and Taco discover that slopesparks are possible.

September 14, 2015

SUPERMETROIDFTP posts this video showing the application of a Superjump to get Plasma Beam before defeating Draygon.

2016

March 5, 2016

WildAnaconda debuts a TAS given to him by sniq which introduces the 14% Chargeless category, and the underflow glitch that makes it possible.

June 4, 2016

sniq discovers that firing a charged beam shot delays the shinespark timer by one frame each time.

2017

June 6, 2017

sniq reveals the Moonfall technique used to uncap falling speed.

2019

January 12, 2019

sniq releases this video, showing that Frog Speedway can be traversed right-to-left with Wave Beam and Spazer, without Speed Booster.

February 8, 2019

BFrobber releases this video, showing a 0-etank Lava Dive is possible. This method ended up being human-viable (though extremely difficult), allowing for Max% GT Code to use the optimal KRDP boss order.

2021

July 27, 2021

During this race dueDillyQueen notices in chat that the rain in Landing Site is moving opposite directions for the two runners. PJBoy investigated this and found it depends on RNG: the rain's X speed is randomly set to -6, -4, or 6.

August 6, 2021

Susreime releases this video, showing that the Zebes Escape timer is disabled by killing Draygon.

2023

May 12, 2023

stashiocat investigates why MB1's turrets can snipe Samus's ammo without even coming close, a common run-ender. Stashio reveals the implications of PJBoy's comments on function $A0:996C. In that function, Samus projectiles and enemy projectiles collide with each other based on whether their center pixels are in the same 32px x 32px grid square. Implication being: projectile centers matter more than their hitboxes and collision can happen with the 2 centers as far separated as 31px apart (or even farther diagonally); Samus should stand forward into the next grid square to avoid a lot of long-distance turret snipes from behind.

Also, Phantoon's eight simultaneous flames that spawn close together can be easy or difficult to destroy, depending if Phantoon is at the center of a 32x32 grid square (easy) or on the boundary of one (hard). And since Botwoon's body, other than the head, is made of enemy projectiles, it can dud Samus's smaller sized weapons from a large apparent distance.
