*****************************************************************
1. If you are human Hell Chaos player, please do your best NOT
to press Up and Down buttons as it might make Hell Chaos
misbehave. I already minimized the misbehavior and only if MUGEN
would have nojump & nocrouch flags for AssertSpecial........

2. I already set guard.dist = 0 in every HitDef but sometimes you
might still enter guard state during Hell Chaos' attacks.

3. Please update your fuddyfunny's Rick at http://www.geocities.jp/xfunnyventx/
My Rick version is ver.1.16.

Once again I edited Neku, with more things added and switched out. It's improvement from what it started as is quite decent. I probably won't update it anymore unless I get more feedback. I'm satisfied with what I have done so far.
