A program to make a Gameboy sprite of up to a 16X16 size. it can only use 4 different shades of grey like the original Gameboy. Select colours at the bottom of the screen. then you can draw the sprite in the white space using the mouse. to erase, select the chequered pattern (the 5th colour). To the right is another colour pallet so you can set the background colour. When done, click 'Generate' to scan in the image. wait for the orange square to scan the sprite (until it gets to the top left corner). It can then be display it on the green-shaded Gameboy screen! You can then edit it and scan in a modified version of the sprite! You can also hold down space to remove the green overlay on the preview (to make it black and white rather than the Gameboy green colour)
