Used by the routine at 606C. Each byte (Q value) here corresponds to one of the 192 columns of the play area (x-coordinates 0-191). The Q value for an x-coordinate uniquely determines the appearance of the corresponding column of the play area; in other words, play area columns that have the same Q value are identical in appearance.
The first 32 Q values correspond to x-coordinates 0-31. In this range, x-coordinates 11 and 13 have the same Q value (0x0B), and x-coordinates 28 and 29 have the same Q value (0x1B).
