+This is an updated version of lr-atari800 to add in missing features.
+
+1) full keyboard support including the SHIFT and CTRL keys, so you can type all the characters. Useful for adventure games, programming in BASIC, etc.
+
+2) four controller support when the emulator is set to 400/800 (useful for games like M.U.L.E.) Note that only the 400/800 had four joystick ports. See http://www.atarimania.com/faq-atari-400-800-xl-xe-what-games-support-4-or-more-simultaneous-players_93.html for a list of games that support four controllers.
