Mode 6 is the least frequently used Background Mode. No games use it.[1][4] It is one of the hi-res modes, meaning the horizontal resolution is 512 dots. When interlacing is enabled, the vertical resolution is also doubled.[1] It supports offset change mode. PVSnesLib currently does not support Mode 6. [2] Color Math should not be used in Mode 6.[3][7] Tiles are 16 pixels wide and 8 pixels tall in Mode 6.[5]

The eight palettes for BG1 are located at CGRAM addresses 0h to 7Fh.[6] Each palette contains 16 colors.

Direct Color is unsupported.[5]

Mosaic and windowing are supported.
