When I use SSDBM it shows the top half of the image twice, and seems to lock the display as I can't clear or alter what is displayed afterwards.


Using the DMDBMP format, it displays a black screen, but if I attempt to display something afterwards it goes nuts. I assume I'm not addressing the BMP data location correctly, but don't see an example or instructions on using a bitmap.
Code:
DMDBMP 0,0,logo64  'X,Y,LABEL      (HOW DO I SPECIFY SIZE???)
gosub show
Here is the code I am running right now with the bmp. Doing it this way seems to get stuck right after the image is displayed, and it looks like the picture below.
