For those who may be interested, here is a compendium of simple hex tweaks and info for editing the title sequence for Super Metroid.
Includes info on the text that appears (after the nintendo logo) and the ceres background sliding sequences, all fully editable as much as possible without asm.
Should prove useful in seeing some better title sequences instead of the regular one for SM we're all used to.

Use RacoonSam's massive tilemap doc on the main site for editing the tilemaps described in here.
