>>10 (Not sure if you still need this, but, hey, whatever) The English patch I have isn't compatable with that mode, so, if you have that one then it might not work.
I really liked the Chaos;Head VN, I never watched the anime though, since i figured that it would ruin it.
Anyone ever figured out what the whole 'fun^10xint^40=Ir2' thing actually was?
