# Used pallete: https://upload.wikimedia.org/wikipedia/commons/thumb/6/66/VGA_palette_with_black_borders.svg/1200px-VGA_palette_with_black_borders.svg.png
# This pallete is the default 256 colors in the Tasm/Masm Extension for VS code, Note that the original asm86 only supported the first 16 colors
# So make sure while drawing your art to pick (via color picker) from this palette, btw: Krita(~30mb) is a great and easy app for creating pixel art:

    # It is okay tho to use black(0) as escaping since there are other codes for the same color like 16, 248..255.
    # if it is .png with some pixels having 0 in alpha channel (making them tranparent: use black(0) as escaping color)
