Thank you very much! but.. hmm, I was going for Pure White WT, oh well, time to do something evil :D
you can go from pure black to pure white like this (what i did):
1. unlock all the fogs before flamelurker
2. starting in pure black world tendency, kill black phantom scirvir
3. without going back to nexus, go almost all the way back to the beginning archstone (near blacksmith). Then head to the rotating platform that brings you to the roof where a fat minister is (along with 2 enemies throwing giant rocks at you before you get there).
4. instead of going to the roof, go all the way to the bottom. there should be a puffed up gigantic enemy that doesn't really attack you. kill it, then head back to the nexus.
5. kill yourself in nexus (if you have the NA version of the game) then go kill a boss in world 2, and this should bring you to pure white.
after killing black phantom scirvir, you will still see the normal scirvir alive in pure white where you fought him in pure black world tendency.
