[3) Data and Player Graphics (Minikernel Developer's Guide)]

Very nice. I used a bit of this in my game.

[1) Background and "Hello World" (Minikernel Developer's Guide)]

I get most of the code, but now why bne in this line stops when y=0. How do you tell it what bank to look at?

 bne minikernelloop ; goto minikernelloop unless the Y register now contains 0
