|  Simple standalone picture viewer
LUMYDCTT v3.8.7
+ generating a simple picture viewer for "Black & White" and "Multicolor"
As you can see the B&W picture is loaded from $4000 because of clear the screen at the start. So after clearing (and setting basics I think) it sets the bitmap position($FF12) to $4000 and shows the picture.
In the other case (Multicolor), not needed the screen clear (I don't understand why need it for B&W), but I cannot reposition luminance and color table... How does $FF14 work? If you try to load the picture from $6000 ($FF12 -> #$18) and set $FF14 to #$58 in vain, because the screen will bring luminance and colour values from $1800 and $1C00 yet. Can only be the bitmap remapped? The default value of $FF14 is 31 --> $1800, so I thought about setting it.
[UPDATED]
LUMYDCTT v3.8.8:
+ Fix a bug! (set multicolor by $FF07 instead of $FF06 and $83)
