XGA (Falcon)

XGA is a family of raw bitmap formats associated with Atari Falcon computers. It is apparently named after one of the Falcon's graphics mode.

Disambiguation
In the PC world, XGA (Extended Graphics Array) was one of the successors to VGA graphics. It's not clear whether this has any relationship to Atari Falcon XGA.
