Just getting situated with the whole Metroid editing thing. I started using SMILE as recommended, but I haven't quite figured out all the features yet. Firstly, how do I place objects (like missile tanks) and creatures? Secondly, how do I adjust palettes? Finally, is it possible to add new creatures to the game data, like say I wanted to add several unique space pirates... would it be within the bounds of the editor to append new entries to the species list?
