im not sure about the second question, but i know for sure that you have to unzip the rom file. its not that hard, i dont see why you wouldnt want to zip it. because of space?
I'm also not sure about the second question, but I am confused about the first. Mother 3 should be a 32MB game as this is the highest GBA games went, the next highest would be 64MB but they never went this high, the games are always fixed sizes (4MB / 8MB / 16MB / 32MB) So should not be 33MB, if you have applied a patch to it this could make it larger, but on it's own it should only be 32MB.
