As I understand it, KQ7 was a fairly rushed production, so there were several updates after the initial release that included bug fixes as well as changes to the interface and even the removal of a couple puzzles.
These are the versions that I am aware of: 1.4, 1.51, 1.65c, and 2.00b. All of them require Windows with the exception of 2.00b, which is also compatible with DOS. (Or in today's practical terms, it can run within DOSBox without requiring Windows 3.1. Highly recommended for avoiding the firecracker bug.) You can find out which version any copy of the game is by opening the file labeled VERSION in the main folder with Notepad.
The Collections have version 1.4.
Version 2.00b had the most drastic changes:
- The game can run in either Windows or DOS (the DOS version has neat colored arrows for the mouse when pointing at an exit)
- The walking speed of your character can be altered by holding the +/- keys (the = key resets to default speed)
- An improved, though somewhat awkward, save game menu (or "bookmark" menu) is added, as opposed to the Quit button simply saving the game and taking you back to the main menu.
- In older versions, the mouse cursor jumps to the lower middle of the screen above the inventory window whenever it turns into a crown. This has been removed for the most part.
- The
crystal dragon death has been removed.
- The ambrosia-on-the-dog puzzle has been removed.* So if you haven't seen that puzzle, then you probably haven't seen the associated
death sequences either.
*It actually depends on where you start the game. If you start at Chapter 1,
this will happen. If you start at Chapter 5,
this will happen. Diamondfist1 informed me of this in the comment section of the first video, and I used it to my advantage in the second video. I started the playthrough from Chapter 1, but since I wanted to include that puzzle, I started a seperate game in Chapter 5, recorded the puzzle, then edited the recordings together to make it look like I never stopped playing (hence my "superpowers" in the video description).
Now that I think about it, I don't think I've ever played an old version all the way through. Maybe the same puzzle disappears then too. That would mean the puzzle's existence would depend entirely on where you started the game and have nothing to do with which version you were playing. Interesting.
As for the original question about the dog barking, I believe he's always there until you talk to Ceres, unless you get really lucky with a glitch. He may still be there after you talk to Ceres, but he shouldn't take long to go away.
