// __settilebg_unsafe
// Write one tile-number byte to the tile map; this selects an existing tile image, not
// new pixel data. LCDC bit 3 selects the background map: zero uses `0x9800`, one uses
// `0x9C00`. The destination is that base plus `32*y + x`.
// Expected: FAILED CHECKS 000, with the written tile data in the selected map.
