A7800 is a fork of the MAME Atari 7800 driver, with several enhancements added:
-Support for emulation of Proline Joysticks, VCS Joysticks, Lightguns, Paddles, Driving Controllers, Keypads, Trak-Balls, Amiga Mice, and ST Mice.
-Maria DMA timing has been improved further, with the addition of accurate DMA hole penalties.
-Improved saturated/normalized 'factory set' default palette colors.
-A bug in the existing RIOT emulation has been fixed.
MAME compatibility and syntax has been maintained, to allow for the reuse of MAME configuration files and front-ends.
