Chase H.Q.: Data at E000

E000: [Stage 2] Horizon graphic

The stage's skyline: 10 bytes wide by 24 rows, 240 bytes in all. It arrives at $5C00 with the rest of the per-stage data, and pre_shift_backdrop makes a copy at $5B00 rotated right by one nibble. Bit 0 of the horizontal scroll then picks between the two in draw_road, so the four pixel shift comes free.
