[stella] Weekend update + timing issue

[Chris Wilkson <ecwilkso@xxxxxxx>]

Hi Joe...

(sorry, I lost the original message...hope it was from you.)

(also:  I hope I'm addressing the right issue!  :)

I looked at the demo on a 2600, and the display rolls vertically.
I assume this is what you were talking about?

You're only doing 119 vertical lines total, according to the 'scope.
Changing your demo source as follows corrects that problem.

        ...
        ...
        ...

        LDY  #149  ;  added 143 lines here for a total of 262 lines
DrawWait
        STA  WSYNC
        DEY
        BNE  DrawWait
        ...
        ...
        ...

I've attached a copy of the modified bin.  Take a look at it to see if
the problem goes away.
