Select your own Jyotyu Palette:

#include "nsmb.h"

void hook_020A3480_ov_00()
	{
		int JyotyuPal = MygetUnk3ForView(((*(getPtrToPlayerActor()+0xAF)>>16)&0xFF));
                if (JyotyuPal > 3) JyotyuPal = 3;

		u8* ptr = (u8*) allocFromGameHeap(1066);
		
			switch (JyotyuPal)
				{
					case 0: //Normal
						{ 
							loadFileByExtId_LZ_Dest(408-0x83, ptr); 
							break; 
						}
					case 1: //Underground
						{ 
							loadFileByExtId_LZ_Dest(406-0x83, ptr); 
							break; 
						}
					case 2: //Lava
						{ 
							loadFileByExtId_LZ_Dest(409-0x83, ptr); 
							break; 
						}
					case 3: //Snow/Ghost
						{ 
							loadFileByExtId_LZ_Dest(410-0x83, ptr); 
							break; 
						}
					default: 
						{ 
							break; 
						}
					//You can add more if you want
				}

		DC_FlushRangeOrAll(ptr, 0x400);
		GX_BeginLoadOBJExtPltt();
		GX_LoadOBJExtPltt(ptr, 0x0, 0x400);
		GX_EndLoadOBJExtPltt();
		
		DC_FlushRangeOrAll(ptr, 0x400);
		GX_BeginLoadBGExtPltt();
		GX_LoadBGExtPltt(ptr, 0x4000, 0x400);
		GX_EndLoadBGExtPltt();
		
		freeToGameHeap(ptr);
		
		return;
	}

Disable broken Unk Setting Functionality:

nsub_0201F0F4_main:
nsub_0201F118_main:
nsub_0201F13C_main:
	MOV		R0, #0
	BX      LR
	
.globl MygetUnk1ForView
MygetUnk1ForView:
	STMFD   SP!, {LR}
	SUB     SP, SP, #4
	MOV     R1, #0
	BL      getPtrToViewById
	CMP     R0, #0
	LDRNEB  R0, [R0,#0xB]
	MOVEQ   R0, #0
	ADD     SP, SP, #4
	LDMFD   SP!, {PC}
	
.globl MygetUnk2ForView
MygetUnk2ForView:
	STMFD   SP!, {LR}
	SUB     SP, SP, #4
	MOV     R1, #0
	BL      getPtrToViewById
	CMP     R0, #0
	LDRNEB  R0, [R0,#0xC]
	MOVEQ   R0, #0
	ADD     SP, SP, #4
	LDMFD   SP!, {PC}
	
.globl MygetUnk3ForView
MygetUnk3ForView:
	STMFD   SP!, {LR}
	SUB     SP, SP, #4
	MOV     R1, #0
	BL      getPtrToViewById
	CMP     R0, #0
	LDRNEB  R0, [R0,#0xD]
	MOVEQ   R0, #0
	ADD     SP, SP, #4
	LDMFD   SP!, {PC}

First goes into a .cpp file, the second into an .s file. You will also need to add this to nsmb.h:

	void GX_BeginLoadBGExtPltt(void);
	void GX_LoadBGExtPltt(const void *pSrc, u32 destSlotAddr, u32 szByte);
	void GX_EndLoadBGExtPltt(void);
	void GX_BeginLoadOBJExtPltt(void);
	void GX_LoadOBJExtPltt(const void *pSrc, u32 destSlotAddr, u32 szByte);
	void GX_EndLoadOBJExtPltt(void);
        void DC_FlushRangeOrAll(const void *startAddr, u32 nBytes);
        void MIi_CpuCopy16(const void *srcp, void *destp, u32 size);
        u32* getPtrToPlayerActor();   //Replace void* getPtrToPlayerActor(); with this.
	u8 MygetUnk1ForView(u32 viewID);
	u8 MygetUnk2ForView(u32 viewID);
	u8 MygetUnk3ForView(u32 viewID);

This hackily lets you choose the Jyotyu palette per view by shamelessly overwriting it directly in VRAM. Simply change the Unk3(B) value in the View settings. 0 = normal, 1 = underground, 2 = lava, 3 = snow/ghost.

EDIT: Minor fix

Oh, you're doing it differently, it seems. Your code uses unk3 as the jyotyu palette number.

The unk1/unk2/unk3 were meant as indexes into the background/tileset blocks in the level header-- those blocks could contain multiple entries. You even have one of the unused levels that uses this.

It's broken as hell because several parts of the code read from the first block or the last block no matter what the unk1/2/3 say. But the jyotyu palette part does work right.

Your hax makes it easier to deal with, though. NSMBe doesn't support the 'multiple BG blocks' thing.

Level Darkness Setting:

#include "nsmb.h"

vu8 *Brightness = (vu8*)(0x400006C);
bool *MenuOpen = (bool*)(0x020CA870);

void hook_020A2ED0()												
	{
		int CurrentView = (((*(getPtrToPlayerActor()+0xAF)>>16)&0xFF));
		if ((MygetUnk2ForView(CurrentView) != 2))
			{
				if (*Brightness != 0) setBrightness(1,0);
				return;
			}
		if (((*Brightness) < (MygetUnk1ForView((CurrentView)))) &&  !(*MenuOpen))
			{
				setBrightness(1,-((*Brightness)+1));	
			}
		if ((*Brightness) != 0)
			{
				if (*MenuOpen)
					{
						setBrightness(1,-((*Brightness)-1));	
					}
			}
		return;
	}

void hook_020A134C()			// Restore brightness on world map
	{
		setBrightness(1, 0);
		return;
	}

This goes into a .cpp file. You also need the "Disable broken Unk functionality" from this post.

By setting Unk 2 in view settings to 2, you enable darkness, the intensity of which is controlled by Unk 1.

I've just noticed, W4-5 area 3 does not have any parallax scrolling between the top BG and the bottom BG. Can it be fixed similarly to W8-6?

                if (JyotyuPal > 3) JyotyuPal = 3;

		u8* ptr = (u8*) allocFromGameHeap(1066);

							break; 
						}
					default: 
						{ 
							break; 
						}
					//You can add more if you want
				}

		DC_FlushRangeOrAll(ptr, 0x400);
		GX_BeginLoadOBJExtPltt();
		GX_LoadOBJExtPltt(ptr, 0x0, 0x400);
		GX_EndLoadOBJExtPltt();
		
		DC_FlushRangeOrAll(ptr, 0x400);
		GX_BeginLoadBGExtPltt();
		GX_LoadBGExtPltt(ptr, 0x4000, 0x400);
		GX_EndLoadBGExtPltt();
		
		freeToGameHeap(ptr);
		
		return;
	}

EDIT: Actually it does this with all your CPP code, not just the jyotyu selector
EDIT2: And yes i'm 100% sure i inserted the new functions into nsmb.h

So i did that but it still says that "MygetUnk3ForView" wasn't declared

Meaning, you need both.

I put the jyotyu and level darkness thingys in two separate .cpp files, and the disable Unknown in an .s file. Is that what i needed to do?
