Used by the routines at 59148 and 62368. T values in this block may be used by play area tiles at y-coordinates 4, 10, 16, 22, 28, 34 and 40; in practice, these T values are used only by tiles at y-coordinates 22, 28, 34 and 40. In particular, the T values at addresses 43039-43119, 43128, 43129 and 43149-43161 are used only by tiles at y-coordinate 40 (which are never displayed), and are therefore effectively unused.
