NTSC Color in Atari 2600

Using NTSC color with TIA(Television Interface Adapter). Really old school~ Cool!

$00 to $7F are for TIA registers to let the TV scaner scan those RAM value. So all the TV render control will put in those address and let TV component scan.

Case:

        ldx #192	
LoopVisible:
        stx $09	; set the background color
        sta WSYNC	; wait for the next scanline
        dex		; X--
        bne LoopVisible 

Result:
