Well to be honest i dont think that the EDGE team is willing to waste some of their bandwidth anymore to release a fix for a game that someone can patch themselves i.e. KHDays (i mean look what happened to the Cyclo DS website) the EDGE team have also once capped their bandwidth as well. Moreover, i don't think that many were fond of playing the JAP release as well.
They are not dead, as long as you see their products being sold on sites then they are still fine.
