"""Atari 5200 conversion dispatch.

The 5200 has the same ANTIC + GTIA graphics hardware (and the same 256-colour GTIA
palette) as the Atari 400/800, so it reuses the Atari 8-bit encoders unchanged.
GR.9 doubles as the monochrome / tinted-mono mode (16 real luminance shades of one
hue).  GR.15+DLI is omitted: per-scanline DLI colour changes need OS NMI vectoring
the 5200 lacks.
