Registry

FUEL and some other Zouna games store some configuration data in the Windows Registry. The root key for FUEL is HKEY_CURRENT_USER\SOFTWARE\FUEL.

Certain values in the registry are able to be overridden by the config.opt file. Some other games do not use the registry at all.

Keys

BitmapEnable

The value of BitmapEnable depends on the checkboxes Enable Normal Maps, Enable Dirt Maps, and Enable Occlusion in the Advanced window in GameSetup.exe. When Enable Normal Maps is unchecked the bits 0xA8 are set, otherwise the bits are unset. When Enable Dirt Maps is unchecked the bit 0x40 is set, otherwise the bit is unset. When Enable Occlusion is unchecked the bit 0x4 is set, otherwise the bit is unset. Naturally, if all 3 checkboxes are set then BitmapEnable is 0, and if all 3 checkboxes are unchecked BitmapEnable is 0xEC. Despite appearing in the same window, the Enable Shadow Maps checkbox has no effect on BitmapEnable; instead it controls the value of VideoShadowMap.

InvertYAxis

This key is read by the game but is not editable in GameSetup.exe. A value of 1 inverts the Y-Axis movement of the camera. This is separate from the OPTIONS -> CONTROLS -> SETTINGS -> Camera Y Axis Inverted option, which is stored in the save file. The registry value and Camera Y Axis value stack together. If both are inverted then they cancel out and it is as if the camera Y-Axis is not inverted. The arrow key camera controls are always inverted regardless of either setting.

MouseSensitivity

This key is read by the game but is not editable in GameSetup.exe. The movement of the camera along each axis is multiplied by MouseSensitivity * 0.0099999998 * 1.5 + 0.5.

NbPlayer

This key is read by the game but is not editable in GameSetup.exe. After the game reads the value, it is immediately discarded since the game loads controls from the save file and not the registry. However, GameSetup.exe uses this to determine the number of ControlsZZ subkeys.

PadsSensitivity

This key is read by the game but is not editable in GameSetup.exe. This value is unused in favor of MouseSensitivity.

UserLanguageID

The value for this key corresponds to a trtext ID.

UserLanguageID	trtext ID	Language
1041	0	PATCH_STR_LANG_JAPANESE_Z
1033	1	PATCH_STR_LANG_ENGLISH_Z

	20	PATCH_STR_LANG_SPANISH_US_Z
	21	PATCH_STR_LANG_TCHINESE_Z
	22	PATCH_STR_LANG_SCHINESE_Z

There is no corresponding UserLanguageID for the trtext IDs 20, 21, and 22.

Version

It is unclear how the Version key's value is determined. The value does not appear to have changed between FUEL and Up.

VideoAdapter

The value for this key is the index in the Video Adapter drop-down selection in GameSetup.exe.

VideoAnisotropic

The value for this key is the Anisotropic Level selected in GameSetup.exe. Disabled is 1, 2x is 2, 4x is 4, 8x is 8, and 16x is 16.

VideoCubeMap

If the value of this key is 0 then the same flags variable as VideoShadowMap is bitwise or'd with 0x40000. This flag appears to never be tested by the game. I cannot notice a difference between having this set or not.

VideoHDRI

This value is a boolean that cannot be set using GameSetup.exe by default, it is possible to edit the setup.cfg file such that a checkbox controlling this registry key appears in the video settings. The game looks normal with the default value of 1. With a value of 0, the game looks overexposed and several meshes are invisible. Recompiling shaders with the value of 0 does not seem to help. Clicking Play or Quit in GameSetup.exe sets this value to 1 by default, it is possible to change this default value in the setup.cfg file.

VideoMode

The value for this key is the index in the Resolution drop-down in GameSetup.exe. However, the VideoResolution key is what is actually used to determine the resolution the game runs at. Clicking Play or Quit in GameSetup.exe sets the value of VideoResolution to the corresponding resolution for the selected index in the Resolution drop-down, overwriting any custom resolution set in VideoResolution.

VideoMultisample

The value for this key is the Antialiasing selected in GameSetup.exe. Disabled is 0, 1x is 1, 2x is 2, 4x is 4, and 8x is 8.

VideoPref

The value for this key is the index in the Performance drop-down in the Advanced window in GameSetup.exe. Low is 0, Medium is 1, and High is 2. This value by itself is only used to store the preset and has no effect outside of setting the checkboxes that control BitmapEnable and VideoShadowMap on selection. The checkboxes themselves are what determine the values of BitmapEnable and VideoShadowMap regardless of the preset selected.

VideoResolution

The VideoResolution registry key is encoded as (height << 16) | (width & 0xFFFF), that is, the height component is the upper 16 bits of the 32-bit REG_DWORD value and the width component is the lower 16 bits. So width=1920=0x0780, height=1080=0x0438 becomes VideoResolution=0x04380780.

VideoSFX

This key is read by the game but is not editable in GameSetup.exe. After the game reads the value, it is immediately discarded.

VideoShadowMap

The value for this key is the checkbox Enable Shadow Maps in the Advanced window in GameSetup.exe. Unchecked is 0 and checked is 1. The same flags variable as VideoCubeMap is or'd with 0x20000 if VideoShadowMap is 0. As expected, unchecking this disables shadows in the game.

VideoTextureFiltering

The value for this key is the index in the Texture Filtering drop-down in GameSetup.exe. Bilinear is 0, Trilinear is 1, and Anisotropic is 2.

VideoTextureQuality

The value for this key is the index in the Texture Quality drop-down in GameSetup.exe. HIGH is 0 and LOW is 1.

ControlsZZ

Note that while by default the registry for FUEL contains these subkeys, they have no effect since the controls are loaded from the save file. The game contains all the logic to load the controls from the registry as described below but does not. Other games allow the controls to be changed using GameSetup.exe, FUEL only allows the controls to be changed via an in-game menu. NbPlayer can be set to 0 and Controls00 deleted without effect.

The subkey ControlsZZ, where ZZ is in the range [0, NbPlayer), has a number of subkeys matching the pattern Control.XX.YY.Primary/Secondary where XX is in the range [0, NbContext) and YY is in the range [0, 32). By default NbPlayer has a value of 1 and NbContext has a value of 3. Not all possible permutations are used by default. The control values are loaded in order sorted by player, context, and control into a list that the game uses when checking bindable controls. This means that adding a new control to the registry will push the index of controls defined after it up by one.

The value of each of these keys is encoded as (data << 16) | (type & 0xFFFF), that is, the data component is the upper 16 bits of the 32-bit REG_DWORD value and the type component is the lower 16 bits. There are four possible type values, each type uses the data component differently.

Conventionally, the Primary keys are for mouse and keyboard controls while the Secondary keys are for joystick controls.

Disabled

A type component with a value less than or equal to -3 represents no selected input for that control. The data component is unused and 0 by default.

Mouse

A type component with a value equal to -2 represents a mouse input. A data component value of 8 or 9 corresponds to scrolling down or up respectively. Other data component values correspond to mouse buttons.

Keyboard

A type component with a value equal to -1 represents a DirectInput KeyCode input for that control. In this case, the data component is a DIK KeyCode.

DirectInput Joystick

A type component with a value greater than or equal to 0 represents a DirectInput joystick, where the exact value is the index of the Joystick. In this case, the data component is encoded as (data_type << 8) | (data_data & 0xFF), that is, the data_type component is the upper 8 bits of the 16-bit WORD value and the data_data component is the lower 8 bits. There are 5 possible values for data_type, each type uses the data_data component differently.

Button

A data_type component with a value equal to 0 represents a joystick button. In this case, the data_data component represents the button index.

POV

A data_type component with a value equal to 1 represents a joystick POV button, a DPad button. In this case, the data_data component is encoded as (data_data_index << 4) | (data_data_direction & 0xF), that is, the data_data_index component is the upper 4 bits of the 8-bit BYTE value and the data_data_direction component is the lower 4 bits. The data_data_index component corresponds to the POV index, the index of the DPad in the list of DPads. A data_data_direction component with a value of 0, 1, 2, or 3 corresponds to up, right, down, and left respectively.

Slider

A data_type component with a value equal to 2 represents a joystick Slider. In this case, the data_data component is encoded as (data_data_index << 4) | (data_data_sign & 0xF), that is, the data_data_index component is the upper 4 bits of the 8-bit BYTE value and the data_data_sign component is the lower 4 bits. The data_data_index component corresponds to the slider index. A data_data_sign component with a value of 0 or 1 corresponds to negative or positive respectively.

Rotation

A data_type component with a value equal to 3 represents a joystick rotation. In this case, the data_data component is encoded as (data_data_axis << 4) | (data_data_sign & 0xF), that is, the data_data_axis component is the upper 4 bits of the 8-bit BYTE value and the data_data_sign component is the lower 4 bits. A data_data_axis component with a value of 0, 1, or 2 corresponds to X, Y, or Z respectively. A data_data_sign component with a value of 0 or 1 corresponds to negative or positive respectively.

Axis

A data_type component with a value equal to 4 represents a joystick axis. In this case, the data_data component is encoded as (data_data_axis << 4) | (data_data_sign & 0xF), that is, the data_data_axis component is the upper 4 bits of the 8-bit byte value and the data_data_sign component is the lower 4 bits. A data_data_axis component with a value of 0, 1, or 2 corresponds to X, Y, or Z respectively. A data_data_sign component with a value of 0 or 1 corresponds to negative or positive respectively.

Comments

The X and Y axis correspond to the left stick while the Z axis and Z rotation correspond to the right stick.

Notably, the F1 key does not appear in the registry despite being used to show the Immediate Mode Popup Menu. Maybe this key is stored in the save file and omitted from the registry despite every other default in the registry lining up with the defaults in the save file.
