Ok, I figured I should try to get a better understanding of 
the INPT4/INPT5/VBLANK thing...
in my experiment, it doesn't seem to matter if I
	LDA #%01000000
instead of just letting it be #0
So I guess I don't get the implication of the
whole latch thing...

Also, I guess I'm still dumb about the bits...
if it's just setting D7 of INPT4, can't you still
use the usual BEQ/BNE, or do you have to use BMI ?
Doesn't LDAing a D7 value effect Z? (actually, I'm
really confused, 

	BNE ButtonNotPressed
	LDA YPosFromBot

*always* skips the COLUBK...I mean shouldn't that be zero
or not zero depending on whether the button is pressed?)
