KC Operating System For The Atari 2600! by Tom Babich
Possibly two updates depending on which Harmony cart you are using: KC_OS_RC5.bin >> This version has demo and playability updates to the classic non scrolling KC and tweaks to the music in the OS. The GUI OS Navigation guide applies fully to this version. KC_OS_RC6.bin >> This version includes a bonus demo "KC Arena" which is not shown on the GUI map, however this version may or may not work on your Harmony cart depending upon which version of the Harmony you have: Fred/Batari and I are working on expanding the early version of the Harmony cart BIOS for improved compatibility with the SuperCharger to handle more than 24K of SuperCharger code. This file only has 5 6k modules and 5x9 header bytes for a total of 29K of actual code including the OS with the rest blank padding. Later Harmony carts and the Uno and PlusCart multicarts can play the bonus version as can the original 1981 SuperCharger via audio tape. Please share both versions for Atari fans and make sure to use RC5 for the party if your Harmony cannot support RC6! :) Details: RC6 contains an extra scrolling KC Arena demo which may be invoked after the first scrolling KC demo (hold the button just for a second) before returning to the OS (hold the button again). If you watch the Arena demo on auto pilot, it has a smooth opening scene where KC catches the power pill eats all the ghosts and sails around to clear the board proceeding to the bonus round right away.
