My retardedness is not quite ended. 

(Though I think
I found part of the bug that was driving me so apesh*t last 
night; I was using 
but accidentally had set it up as
Varname ds 1
--that don't work so good  (reserving only one byte, 
for those not used to reserving RAM like that))

My first efforts to integrating Paul's great kernal 
show a lot of promise, but now I'm again weirdly stumped;
he's doing some stuff I don't understand with stack restoration
and what not, but I can't for the life of me figure out what's 
moving the shared P0 graphic between the title kernal and 
the game itself...Paul's careful positiong works great for 
the title screen, I then take care to zero out HMP0, "just
in case", and I can't find any calls to RESP0 or HMP0 after 
that...but P0 has shifted, which of course messes up the timing
of what's displayed when and where...

Gah.  I'm such a perpetual n00b sometimes.

Thanks if you can take a look at this!
