I need a quick bitmap rendering routine, that can take the following inputs. The source of data is an AP program, opened by the program I'm writing. Below, I list the data provided to the viewer, in the order it occurs. You can ignore byte 5. That is just a timer loop, controlling how long it waits before rendering the next item to the "slide":


;Data Format:
;Byte 1= xstart
;Byte 2= ystart
;Byte 3= number of bytes across/8
;Byte 4= number of pixels down
;Byte 5= timer
;Byte 6+= rows of data

This looks like something you could write. I have faith in you. Basically, what you have to do is: take Y Start, multiply it by Width/8 and add X Start and 5. That will be where you start your ldir, so it will be HL. Then you store gbuf to DE, and 767 to BC, and ldir. Yeah, that should be it.
