you actually can wallkick out of a roll out if you slow down your momentum when doing it. idk exactly about sirena 2 but i can see it being possible by using the boo's in a good way. It's pretty unrealistic to bring such a category on the lb's if you ask me. you should ask a mod directly since i'm not sure if the mods check this regualarly. i think this could be a fun run afetr all.

are there any diffrences betwen ntsc-J and ntsc-U?

Can you might change my Name to "GrinchSMB" Thank you very much :P
