(Not to repeat everything gentlben wrote, I just want to make >sure I have the logic right.) This is pretty much correct. VSYNC lies in the zeropage though, therefore a lda #$00/STA $00 will be smaller and faster and have the same results as your code above. >So VBLANK just sends out whatever color is in the background register >at that time, huh? Could come in very handy. No, VBLANK turns the display off completely. When VBLANK is turned on, the electrom beam will only produce black.
