Row codes:

How to create your custom graphics (sprite)?

*1. Draw the graphics on paper.*
Take a piece of checked paper.
Draw a rectangle around a 8x8 area. Design the
graphics: fill in some cells with the pencil.

*2. Calculate the row code for each row in the graphics.*
Write the following numbers above cells of the first row, in
order: 128, 64, 32, 16, 8, 4, 2, 1.
Now for each row, look at the filled in cells.
In a row, add all the numbers above filled cells together.
For example, if your row has the first (128) and last (1)
cell filled, write down 129 (which is 128 + 1).

3. Finally enter those numbers in the field above. Some ideas to draw: cup, ball, face, spaceship, horse.

Bonus exercise: try to POKE the codes into C64 or ZX Spectrum.
