v5.6
Creates a custom character. Each character is divided into 8 rows of 5 pixels; each data byte represents one row.
Each byte is padded by three zero bits followed by five bits representing each pixel state. A one represents an on
condition while a zero is off. Characters are lost when a new memory bank is loaded, unless they are saved.
