AGI was the in-house, parser-based EGA game engine that Sierra used for its adventure games in mid-80s (e.g. Police Quest 1, King's Quest 3, Leisure Suit Larry 1). King's Quest 4 was finished with AGI, but then Sierra decided to upgrade the game to the newer SCI engine which allowed for better graphics (SCI engine was later used for Police Quest 2, Colonel's Bequest, and Hero's Quest 1, to name a few).
This AGI version was actually released, but was pulled from the shelves and replace with SCI version very quickly.

Could you please add this here? https://www.adventuregamestudio.co.uk/play/game/2907-king-s-quest-iv-retold-vga-talkie-/ This is a completely free-legal-developed version of this game. It's completely fan-made and legal. I can't download it from the original site because I can't access it. Please upload this game here. It's a very important game to me, but a week has passed and I still haven't been able to play it because I can't find another link.
I prefer the version with SCI engine and improved EGA-graphics.
i love kings quest till the 7th one came out
Thanks to download the game king s quest
The damn stairs and ledges! Get me every time.
Has anyone been able to download these games?
Thx Nowhere Girl for the tip on how to bypass the copy protection
To save, Change your directory of Save (i.e. change from C: to A: or to a USB Flashdrive). Try saving to other directorys.
How do you save?
Never let a blind man peek.
This might be the best game ever.
Simple way to bypass copy protection: press alt-D, then type "marble". By the way, if you type "pirate" instead, the game will end, but it's an Easter egg - worth trying.
It's really a treasure - the AGI version is very rare. It sure looks worse, but not that bad - it was one of the last AGI games and by that time the developers had learned to squeeze the most out of this engine. No more Lego-like figures, like in the first two parts of "King's Quest"... And this version contains a pearl: a funny, anachronistic Easter egg which is exclusive to this version. Probably you've read about it: after defeating Lolotte and, if I remember well, before going downstairs, type "beam me" - in the left side of the hall, I guess (the goons aren't a threat anymore at this point because they are grateful too to be rid of Lolotte ;)). Quite a lot of funny information and a room completely out of tune with the rest of the game.

Manual has been added ;)
There's no manual. Copy protection but no manual to get the answers out of. ;)
