Using Photoshop:

clean-up & use Levels  (to increase contrast)
resize image to:  160x96  (bicubic sharper)
add dither & threshold layer  (as seen in example file)
	Recommend Dither turned off, or at:  20%
	Recommend Threshold at:  129
flatten layers
Convert to "bitmap" color  (menu: Image -> Mode -> Bitmap)
Save as .BMP file
