KQ43 Icon
King's Quest XLIII is a copy of a future King's Quest game found on the Super Computer on Xenon in the Space Quest series. It is the 43rd game in the King's Quest series.
Background[]
The software probably represents some tertiary function of the Supercomputer Brain. Certainly nothing important.
In the super computer in Space Quest IV's Space Quest 12 era, is another King's Quest (Roger Wilco saw another game in the series while in the Space Quest X era, see King's Quest XXXXVIII: Quest for Disk Space). Interestingly, this 'other' game can be deleted from Sludge Vohaul's computer. When deleted, it will significantly free up space (although far more data than 12 gigabytes).
When the game is deleted it is discovered that it was roughly 841,912,226 Gigabytes (or rather 842 Petabytes). Much larger than any present game.
