Hello altogether,
I am not a TASer, but I research all kinds of glitches and mechanics for Super Metroid and try to analyse various categories for this game, so I figured that it could potentially be useful in general if I provide my resources here, since I do not know if most of my new stuff is well-known already.
The place where I usually update and gather everything regarding Super Metroid that I have is in this thread over at the Metroid Construction forum:
http://forum.metroidconstruction.com/index.php/topic,3204.0.html
Edit: I finally read through all 257 pages of this thread more or less carefully, and found some more glitches/tricks that I did not know yet and will add that knowledge into my Super Metroid physics compendium at some point. Also, are there categories or TASes that are still worked on in here?
To my knowledge, the only items that could be generated OoB up to now are R-Tanks (but then the game crashes) and Varia-Suit (without crashing the game) due to Sniqq´s research.
