KISS - Kerbal Improved Save System

is an add-on for the game Kerbal Space Program that provides an improved "Save game as..." mechanic while in flight.

The KISS window is activated by pressing "F8" (can be configured, see notes below) and provides the same functionality as the stock "Quicksave as..." dialog ("MOD"+"F5") for creating named savegames. In addition KISS provides the following improvements:

  1. It lists all existing savegames for your current game and allows you to select a previous savegame to overwrite it.
  2. The suggested name for the new savegame can be configured:
    • the current timestamp and the name of the active vessel (ship) ("{timestamp}_{vesselName}") (default).
    • the name of the activ1 vessel (ship) and the current timestamp ("{vesselName}_{timestamp}").
    • "quicksave" (useful for quicksave mode).
  3. The timestamp can be either your current system time ("YYYYMMDD_hhmmss") or KSP ingame time ("Y1_D01_0_24_56").
  4. Quicksave mode: if enabled pressing "F8" will instantly save your current game without showing any GUI (press "MOD" + "F8" to show window again).
  5. It allows you to delete old savegames directly from within the game!
  6. It can create savegames while in a vessel that is moving on the ground (because it pauses the game before saving)!

In other words: KISS allows you to manage your quicksaves without the need to memorize quicksave names!

Known limitations of the keybinding feature:

  • you can't bind any modifier keys (Shift, Ctrl, Alt, Command,...) and you also can't have any key combinations for KISS, you can only pick a simple, single key.
  • you have to disable Capslock before assigning a new key if you want to make sure it is labeled correctly in the UI. Unfortunately it is currently impossible in Unity to check if Capslock is on.
  • on international keyboards, you have to hit special keys twice(like the accent keys " ´ " and " ^ " on the German keyboard), because they do not produce a character when hit for the first time, but I need the character to label the key correctly.
  • all keys that to not produce characters like Backspace, Arrow Keys, etc. are labeled with their English names, regardless of keyboard language used.
  • the "Print" key is for some reason not detected by my code (although it is listed as a viable KeyCode in Unity).

Current version: 2.4.2

for Kerbal Space Program 1.9.1 +
