The count of how much booty the player has collected in the current game.

Initialised to 0000 in InitialiseGame at the start of a new game, unless GameState is set to "Game Looped Mode" (2) in which case the game begins with the previous games value continued (but all the booty is respawned).

Used by the routines at InitialiseGame, PrintStatusBar, AnimalsEventTiming and Handler_Items.

Probably could name this better - this represents the number of frames to skip before counting down the actual Golden Key Timer at 23551.

Used to assist with populating TableRoomData, as this table is blank when the game is first loaded.

Note that room ID 22 is never used, and hence is 0000. Room ID 21 is a valid reference (and does have data), but also is not used in the game.

See PopulateRoomBuffer for usage.

Contains the currently in-focus key position; used for highlighting.

See SetDefaultKeyboardInputs for an example of how this is used. Each key is stored as an offset. So a stored value of 5 equates to the "T" key.

This value is incremented every frame, and every 4th frame will cause the player to rise.

The number of fish needed to complete the game; see 52823.

Populated by PopulateSandBuffer.

See TablePlayerAttributes.

This value is incremented every frame, and every 4th frame will animate the port holes (if there are any). See Handler_PortHole.

Used by the routines at Handler_Bomb (for creation) and Handler_Explosion for animation.

Initial values are populated from TableDefaultBombSparks.

Used by the routine at Handler_Bomb.

These default values are copied to TableBombSparks.

Keeps track of the current position in the room buffer being processed.

Used by the routines at ConvertCoordinateToBufferOffset, PrintSpriteUpdateBuffer, 59396 and Handler_Pirates.

See Handler_Lifts and Handler_Pirates.

The width of the sprite actively being printed.

The ID of the sprite actively being printed. Note; this starts off as -1 of the real value as it increments to the base sprite ID in the printing loop.

Used by the routine at InitialiseGame.

See 58496.

Used by the routine at GetRandomNumber. Not random at all!

Incremented address which points to ZX Spectrum ROM for the purposes of creating the screeching noice you hear when the bomb is counting down.

Increments by one on every generated interrupt.

Keep track of the current position of the music data. This is important as the theme tune uses interrupts to play, so it needs to know where to resume playing from.

Used by the routines at GameEntryPoint, ResetSoundFlags, LoseLife and 63624.

Used by the routines at GameEntryPoint, Handler_Player and 63624.
