; Put a single-line overlay to display status information
Overlay
:top equ 16
ldy #$2222
; An overlay is a callback from the render to shadow in a range of lines. At a minimum, the overlay
; code needs to LDA/STA or TSB slam the data, but an overlay is typically used to draw some graphic
; on top of the rendered playfield, such as a status bar or in-game message
;
; This overlay implementation is for a status bar that is 8-lines height that will be used to display some
; status information. The interesting bit of this implementation is that it's split into two pieces,
; a left and right section in order to be able to use the same code for different screen widths, but
; still keep the content in the cornders while covering the full screen.
;
; There are two subroutines that need to be implemented -- one to update the overlay content and a
; second to actually render to the screen
