Patch:Main menu (Galaxy)
This page covers patches relating to the main menu, the first menu the player is confronted with on starting the game. Related pages are Patch:Title screen. For patches relating to the main menu in other games see Patch:Main menu (Vorticons) and Patch:Main menu (Dreams).
The Galaxy menu is more closely related to Keen Vorticons' menu, but is also like the Dreams menu in that it also uses bitmaps (it even has its own fullscreen graphic). It is also much more complex than the Vorticons menus.
This page is divided into several sections. The first two sections are minor and deal with disabling the entire menu and playing music when the menu is called. They are pretty self-explanatory. The third section deals with menu bitmaps in general and the range the menu can use. More useful is the fourth section which details 'menu segments'; these control how the various menus are laid out, their texts and bitmaps, a very broad and powerful set of tools. The fifth section pertains to menu 'bars', that is horizontal lines that divide up the menus. The sixth section involves 'colors' and deals with the colors of various texts and objects in the menus. The remaining two sections are minor and rather miscellaneous things.
Disable
There are two parts to this patch, the first disables accessing the Main Menu during normal gameplay by pressing the F2-F6 keys or Esc. The second part skips going to the Main Menu when the game is first started, instead launching the demo mode game.

This patch shows what controls the blocking of the Main Menu ingame. Ordinarily this is 'demo mode', a special gameplay mode activated by the -demo switch. This can be changed however so that the menu is permanently or temporarily disabled.

This patch changes things so that when the game is started there is no Main Menu, instead the player is sent straight to a new game. The second line controls the difficulty of that game; by default it is 2, or, normal.
Note that the player can still access the menu and quit the game\start a different difficulty if they wish.

This allows you to play music in the main menu. As a side effect the menu background color is black, not cyan. This only matters if your menu image is smaller than 320x200. The value used here is the level whose music is used. (For example a value of 0 will play the map level's music.) See Patch:Music.

Menu doesn't stop game music
This patch lets the game music keep playing when the menu is called. This means the music playing in the level or demo the player plays before calling the menu. When the game initially starts the menu will be silent.

Menu bitmaps
The Main Menu uses a variety of bitmaps. Primary among these is the 'background bitmap' that fills the entire screen and over which other bitmaps are displayed. These 'sub bitmaps' are called by various 'menu actions' (See below.)
As such all these bitmaps must be cached when the menu is first displayed. They are also displayed in the same location onscreen (despite being different sizes.)
Bitmap cache
The bitmap cache controls all the possible bitmaps the Main Menu can display. Note that while the first value is a word, the second is only a byte. At the same time it also caches the required sprites for the Paddle War minigame and the 'DEMO' sign for demo display. The sprite images used for Paddle War are cached at a different location when the minigame is loaded.

Background bitmap
This is the 'background' bitmap used for the main menu, in short Keen's computerwrist. If this is not displayed the game will show the menu text and bitmaps over a blank screen. There are two separate uses of the bitmap, one for all menus except Paddle War, and one for Paddle War itself.

Menu name bitmap locations
As stated above, all the menu name bitmaps are displayed in the same location, no matter how wide they are. (They are the same height.) The actual bitmap displayed depends on what menu the player is currently in.

Menu actions
The structure of the Main menu's actions and options is discussed in detail in this tutorial page. Menu actions and options control most of the menu text, the number of options in menus and how they are laid out, the bitmaps that appear and more.
This is a 'hidden' menu not seen during normal gameplay used by the developers when debugging the game. By default it can be ignored. It contains only one option 'DEBUG' and it is not known how functional this is.
This menu uses the 'MAIN MENU' bitmap and its only option is type 1.

This menu allows the player to control how sounds are played in the game. It has four options, each of type 2. Each item uses its third value for a currently unknown function.
The menu itself uses the 'SOUND EFFECTS MENU' bitmap and positions all its options 8 pixels right of the Computerwrist's left side.

This menu allows the player to select the difficulty of a new game from either Easy, Medium or Hard. It has three options, each of type 1. Each item uses its third value for a currently unknown function. The fifth value controls what kind of game is started; 5 starts an easy game, 6 normal and 7 hard.
The menu itself uses the 'NEW GAME MENU' bitmap and positions all its options 8 pixels right of the Computerwrist's left side. Its eighth value is 1 for unknown reasons. It is possible to add a fourth difficulty option to this menu by using the (unused) debug menu.

This is one of the more complex menus. It has two menu setups as well as multiple 'blank' options filled in by saved game data. The first menu is the load menu used when loading games while the second is the 'save' menu used when saving games. Both menus offset their texts 4 pixels horizontally and 3 pixels vertically and use the same options. Each menu has its own unique code to run when in use.
Each option is type 1 and its third value controls what game is loaded. (2 loads game 1 and so on.) Each option has no text associated with it, this is supplied by the saved game entry for that option.

This menu allows the player to modify several options in the game such as turning the scorebox off and on. It uses the 'OPTIONS MENU' bitmap and displays text 8 pixels right of the computerwrist's left side. There are also four 'option menus' run by each menu option when it is selected.
There are four menu options none of which has text since the text must change when the option is turned off or on. (The text must be patched another way.) It is not known what the text field does in these options, it appears to simply point to empty text strings to avoid displaying anything. The options are all type 3 and have their own unique codes to run when selected.
The last four menus have no text offsets or bitmaps to display. Their function is to run code when a menu option is changed, changing that option and the text displayed.

This menu allows the player to change which keyboard keys make Keen jump, pogo and shoot. It has three options all of type 1, one for each action. Each option has its own text. The menu itself uses the 'BUTTON SETUP' bitmap and uses the same code as the movement setup menu.

This menu consists of two different parts. The first menu lets the player pick between the movement and button setup menus. It has two type 3options each with their own text and code to run when selected. The menu itself uses the 'KEYBOARD MENU' bitmap.
The second, third and fourth menus switch control to Joystick 1, Joystick 2 and the Gravis Gamepad respectively. They do not change the screen or menu and instead are called by the Configure menu, run some code then return control to the Configure menu. As such they are not quite separate menus. It can be seen that they have no options but do have their own bitmap to display.
The two options themselves call two menus the movement and button configuration menus.

This menu lets the player pick between the configuration menus. It is as such the most central menu. It has seven type 3 options, each with its own text. (Except that last which points to blank text.) The menu itself uses the 'CONFIGURATION MENU' bitmap.
Each option calls its own code, usually another menu. The last three options call a menu that doesn't change the screen and keeps the player in the options menu.
Notice the last option has no text. This is because its text must change depending on whether or not the Gravis Gamepad is active. The fourth option ('keyboard') has a second variable value of 8, which moves the next line down 8 pixels, creating a space between the first four and last three options.
Patches relating to how the menu's code works (What variables it can alter, how it behaves when an option is selected.) are covered under Patch:Configuration options.

This menu is the most central menu of the game, the one that first appears when the player leaves the title screen or presses 'Esc' during gameplay. It leads to all other menus.
It has only one menu setup using the 'MAIN MENU' bitmap. Text is 20 pixels right and 4 pixels down from the top left of the Computerwrist screen.

This menu is called by the Main menu when the player selects the 'Paddle war' option. It runs the Paddle war code. It has no options or text or bitmaps to display as that is handled by the Paddle war code.

Bars
The bars are horizontal lines of color that separate various sections of the menu. The Main menu has two, a top and bottom bar. All bars have four variables of interest. The first is the bar's color, the second how far down the screen it appears and the last two are the left and right ends of the bar. There is also a patch to remove the bars entirely. (Or their vertical position can be set to 0.)

The colors of fonts are opposite those of other items. Thus $02 is dark green and $0A is light green for most menu components, but the exact opposite is true for fonts. Items that involve font colors are marked with an * so the patcher can be made aware of this.
Things that can't be patched
Two sorts of menu items cannot be patched, or rather cannot be changed by patching. these are the 8x8 tiles (Used for the menu cursor for example) and the menu graphics (For example the image that says 'MAIN MENU' in the main menu.) These need to be altered with a graphics program to change their colors.
Main Menu and general setup
This is the menu the player is first presented with. It's graphic reads 'MAIN MENU' and it lists all the other options and sub-menus the player can access.
It consists of three parts, a top section, (Containing a single divider line and the menu graphic.) the middle section containing various options and a bottom section (Containing a divider and menu controls text.)
The Main Menu setup is used by most of the sub-menus (Such as the configure menu) so patches here have the widest effects.
The first thing that can be changed is the background. When the menu is drawn, first the menu graphic is drawn onscreen, then a box of a certain width and color is drawn over it. THEN the text is drawn over this. Changing the background color will also change the color of the font displayed on it, so be careful.
By default the background is $08 or dark grey so as not to interfere with font color. In the patch above two values for this are given, both must match. It is not wise to change the width of the background box, for if the text is too large for it, much confusion results.
It is also possible to change the color of the menu text. There are three main colors, selected, unselected and the text that appears at the bottom of the menu (Telling you to use the arrows to move and so on.) There are two less well known text colors, one light grey, one black. Finally the top and bottom divider line colors can be changed.
Menu Message Box
This box appears over the main menu, such as when the player selects the 'Quit' option. It is made of a top, bottom, left and right line with a bar in the middle that separates the top and bottom texts. It also has a background color that works the same way as the main menu. Each of these item's color can be changed. (Notice this box can have different text in it depending on what it's being used for, but the colors will remain the same.)
This mostly uses the Main Menu's colors except for the text explaining what currently controls Keen (Keyboard or joystick.) this has its own color.
This is part of the configure menu and appears when the player wants to change what keys move Keen. It consists of two separate, but similar menus that consist of a list of actions paired with boxes showing what key controls that action.
As a separate menu it has its own background color setup, identical to that of the main menu's. It is also possible to change the selected and unselected text colors as well as the border color and background color of the boxes that show the current control keys.
Things get more complicated when a key is selected. The boxes containing the control key get their color from the selected and unselected text, plus a modifier. By default this modifier has no effect, but if it is patched, odd things can happen, so it is suggested that patchers be very careful when altering it.
These menus are much simpler than the keyboard menu, having only a background and text color.
This consists of a series of savegame positions, each a name enclosed in a box. The color of the box is controlled by the same variable that controls that of the text. The 'selected' text color is the color of the selected game and also the color its box 'blinks' The text color modifier affects text color by adding to it. It thus affects both the selected and unselected text colors. By default it is $08. There is no point in patching this. There is also a background color, as well as a text AND background color for when the player is typing a name for their saved game.
This applies to windows that appear when the menu is being loaded or closed. (Such as the 'Demo' window when a demo is starting or 'Control panel' when the menu appears.) All that can currently be patched is the text color in these windows. They are not really part of the main menu proper.
Menu mask
When certain actions are selected, such as the 'Quit' option, the menu is masked to show its inacessibility. By default this uses a masked bitmap that is a checkerboard pattern of grey pixels, placed over the menu screen to half-erase the text. The bitmap can be changed, moved and even prevented from appearing entirely.

Main Menu Demo Loop
The main menu demo loop is the sequence of events that plays out whenever the player selects 'Return to demo' from the main menu. The default sequence is 'play demo 1, story screen, demo 2 highscore demo, demo 3, demo 4' (Then the terminator text will display, resetting the cycle.
To remove an item from the loop simply replace its '$9A $xxxxxxxxRL' string with '$90 $90 $90 $90 $90' Items can also be rearranged, though this takes a little more nuance. It is also possible to rearrange the order the demos play in by changing the numbers before the demo calls. (See section below on demo numbers\disabling demos.)

Demo loop list
This is the pointer list to all the items in the above code. By simply swapping various pointers around it is possible to change the order that various actions appear or replace one action with another. A novel option is to replace the terminator text with the star wars story
