Patch:Game over (Vorticons)
This page contains patches relating tot he Game Over sequence. This is triggered in one of three different circumstances, when the player quits their game, when the player loses all of their lives and when the game is won. The sequence may differ depending on circumstances. Closely related patches can be found at Patch:High Scores (Vorticons).
In Keen Vorticons the Game Over sequence may or may not ask the player to enter a high score, depending on their score. The sequences are so tightly interwoven that it is difficult to separate them ad this 'high Score Entry Window' will be treated here as part of the Game Over sequence. It contains a congratulatory message and allows the player to enter their name. After this the high scores are shown and the game ends.
Note that this is actually slightly more complex. First the SCORES.CKx file is read to see if the player actually has a high score. If not then the Game Over bitmap is shown, otherwise the high score window appears and the score is entered. In either case the game then goes to the high scores screen.
No GAME OVER
This patch removes the GAME OVER entirely; instead of seeing the GAME OVER or Highscores textbox the game simply quits directly to the Main Menu.

No GAME OVER when out of lives
This patch stops Keen losing a life when he dies and disables the GAME OVER check. This means that Keen can only experience a GAME OVER by quitting the game.

GAME OVER\High score sound
A sound is played when the game is over whether or not the Enter High Score Window appears. This can be blocked.

GAME OVER bitmap
The GAME OVER bitmap is displayed over the high score window and is onscreen whether or not the Enter High Score Window is present. Changing this will also change the game over sequence when Keen does no have a high score.

High scores window
No Enter High Scores Window
This patch completely disables the Enter High Scores Window. When quitting or winning a game the player will simply be sent back to the main menu no matter what their score. As a side effect this will also happen when the player runs out of lives, there will be no GAME OVER bitmap shown.
A second patch is available that avoids this side effect, in this case the player will simply never be able to enter a new high score, they will always get the GAME OVER instead. In either case this means that the default scores can never be changed.
No high score window or game over

Always display Enter High Scores Window
This patch displays the Enter High Scores Window whenever the player quits or wins the game, even if they have no high score (even if they have no points!) The player will be able to enter their name, but their score will not be added to the high scores unless they do in fact have a high score.

Window size and text start
The basic window setup common to all three games is a 13x32 window with a GAME OVER bitmap at the top. Aside from this text and other objects displayed differ between games. The text in the window starts a certain number of lines down from the window top.

Score base and don't show score
This patch changes the base that the score is shown in. By default this is base 10 (Numbers 0-9). If it is shown in base '0' then the score will not be shown at all.

Ship parts tiles
In Keen 1 four ship parts tiles appear in the Enter High Score Window if Keen has obtained them.
What makes the ship parts appear in the window
This patch controls what makes the four parts tiles appear in the Enter High Scores Window. By default they are shown if the relevant part value is not 0. (See Patch:Jump conditions.) Changing all four $74s to $EBs will ensure none of the tiles are ever shown. See also Item bytes.

%patch $8C85 {$AA98W} [$00] $74 #Whiskey
Parts tiles locations
In Keen 1 up to four parts tiles will appear in a line if Keen keen has them. The line's vertical location is patchable. Altering it will alter the vertical position of all four parts tiles.
Parts tiles have three variables that determine their location relative to that line; two of those variables alter the vertical location and one the horizontal. The horizontal and first vertical variables are in multiples of 8 pixels (Thus a value of 2 is 16 pixels and so on.) The second vertical variable is in single pixels.
The two 8 pixel variables have an odd quirk, the value $0002W or 16 pixels is instead represented as $40 $40 and it can only be changed to $40 $90 (8 pixels) or $90 $90 (0 pixels).

Window text
The Enter High Scores Window contains three lines of text, a statement of score, congratulations and a request to enter the player's name. In Keen 2 mention of how many cities the player saved is also included, this is treated separately below. The 'first, second', etc text is a special case, explained in a subsection below.

Keen 2 cities saved text
In Keen 2 the player is told how many cities they have saved. If they have saved none the text reads 'You saved no cities!', if one city is saved then the text reads 'You saved 1 city!', and if more than one city has been saved the text reads 'You saved x cities!' where x is the number saved.

%patch $1A64E "no cities!" $00
The variable scanned can also be patched so that the high scores counts something else. By default it is the 'cities saved' variable increased every time a Tantalus Ray is destroyed.

First, second, etc place text
The text for what place the player gets is called in a complicated manner. By default a string of a certain length is called at the start. The player's place then defines where the game starts reading the text, reading until the first $00. This effectively 'cuts' the string into smaller segments. By default
As such only three variables are needed, the location of the score position text string, the length of that string and the length of the segments it is divided into.

Maximum length of high score name
The player's high score name cannot be of any length; it must be equal or less than a certain number of characters. This patch controls that maximum length. Note that if the length is made longer than 12 characters problems will occur with saving the name to the SCORES.CKx file.
