SPRITE DEFINITION MODE
Here's the general procedure to create a sprite in SPRite DEFinition mode:
1. Clear the work area by pressing the shift and CLR/HOME keys at the same
time.
2. If you want a multi-color sprite, press the M key and the cursor (+) appears
twice as large as the original one. The double-width cursor appears since
multi-color mode actually turns on two pixels for every one in standard
sprite mode. Multi-color sprites have only half the horizontal resolution of
standard sprites.

16, hold down the Commodore (0) key and press a key between 1 and 8.
4. Now you are ready to create the shape of your sprite. The numbered keys 1

key to fill a character position within the work area. Press the 1 key to erase
what you have drawn with the 2 key. If you want to fill one character
