So, I am actually still confused on the general implementation of screen scrolling.

Can someone clarify a bit more the process to enable screen scrolling?  It's essential to the working of my Chapter 9 game project.  Thx.

Scrolling is not implemented in the supplied Output.vm file nor in the VMEmulator program.

In chapter 12, you will write your own version of Output.jack.  That is where you can write code that supports scrolling.
