The first timecyc ambient field is actually reversed in PSP versions

[santiago046]

These ones in PSP are actually "read" as BGR in the PSP versions:

g3DTZ/source/core/TimeCycle.h

Lines 16 to 18 in 64f3804

	uint8 m_nAmbientRed[24][8];
	uint8 m_nAmbientGreen[24][8];
	uint8 m_nAmbientBlue[24][8];

For example, in the midnight entry for sunny weather, it should be 255 182 178 instead of 178 182 255 in the LCS PSP extracted timecyc.dat file.

lcs_cdr_timecyc.mp4

Also,

g3DTZ/source/core/TimeCycle.h

Lines 111 to 120 in 64f3804

	int16 m_nCurrentShadowStrength;
	int16 m_nCurrentLightShadowStrength;
	int16 m_nCurrentPoleShadowStrength;
	int32 m_nCurrentFarClip;
	int32 m_nCurrentFogStart;
	#if defined(VCS) && defined(PS2)
	int32 m_nCurrentRadiosityIntensity;
	int32 m_nCurrentRadiosityLimit;
	#endif
	int32 m_nCurrentLightsOnGroundBrightness;

seems to be read as:

	int16 m_nCurrentShadowStrength; 
	int16 m_nCurrentLightShadowStrength; 
	int16 m_nCurrentPoleShadowStrength;
	uint8 Padding[2]; // Padding for alignment
	float m_nCurrentFarClip; 
	float m_nCurrentFogStart; 
#if defined(VCS) && defined(PS2) 
	int32 m_nCurrentRadiosityIntensity; 
	int32 m_nCurrentRadiosityLimit; 
#endif 
	float m_nCurrentLightsOnGroundBrightness

Assuming the current weather is sunny midnight:

g3DTZ/source/core/TimeCycle.h

Lines 130 to 146 in 64f3804

	int32 m_nCurrentBlurRed;
	int32 m_nCurrentBlurGreen;

	int32 m_nCurrentWaterRed;
	int32 m_nCurrentWaterGreen;
	int32 m_nCurrentWaterBlue;
	int32 m_nCurrentWaterAlpha;
	#if defined(VCS) && defined(PS2)
	float m_nCurrentBlurAlpha;
	float m_nCurrentBlurOffset;
	#endif
	int32 m_nCurrentStoredValue;
	int32 m_nFogReduction;
	int32 m_nExtraColour;
	int32 m_nExtraColourOn;
	int32 m_nExtraColourInter;
	int32 unk;

are read as:

	float m_nCurrentBlurRed; 
	float m_nCurrentBlurGreen; 
	float m_nCurrentBlurBlue; 
	float m_nCurrentWaterRed; 
	float m_nCurrentWaterGreen; 
	float m_nCurrentWaterBlue; 
	float m_nCurrentWaterAlpha;
#if defined(VCS) && defined(PS2)
	float m_nCurrentBlurAlpha;
	float m_nCurrentBlurOffset;
#endif
	int32 m_nCurrentStoredValue; // Loops continuously from 0 to 15.
	int32 m_nFogReduction;       // Increases by 1 when a cutscene starts, up to a maximum of 64, then stops.  
                                     // After the cutscene ends, it decreases by 1 until it reaches 0, then stops.
	int32 m_nExtraColour;        // Only takes effect if the next field is greater than 0.  Values greater
                                     // than 23 can cause extreme effects, such as a solid color overlay
                                     // (e.g., light yellow) or a tinted screen. For example, `0xEE`
                                     // applies a reddish overlay that affects the entire screen.
	int32 m_nExtraColourOn;      // When changed to a value greater than 0, it activates the effects of
                                     // `m_nExtraColour` and `m_nExtraColourInter`.
	float m_nExtraColourInter;   // If `m_nExtraColourOn` is greater than 0, this starts at `1.0`; otherwise,
                                     // it remains `0.0`. If set to `0x00000000` while `m_nExtraColourOn` > 0, 
                                     // it gradually increases until reaching `1.0`.
	int32 unk;                   // Always zeroed; has no observable effect.
