Lots of data on Metroid Fusion and Metroid: Zero Mission, with a bit of Super Metroid on the side. Worth looking into.

Kejardon
Super Metroid Documentation (external link)
The revered "Kej's notes" that everybody hears about at some point in their lives. Even homeless Lithuanians who have never touched a computer know what these are. If you're serious about hacking Super Metroid, these notes will prove to be a very valuable resource.

BlackTelomeres
SMILE FAQ (external link)
Somewhat dated, but the information is detailed and still relevant for the most part. I (Grime) learned a lot from this page when I was new to editing Super Metroid.
