Overlay 10, i.e where the code is.

Code goes like this

MOV R4, R0 <- Original instruction that was there. Moves the Player Address to R4 so we can operate on R0-R3.
LDR R0, =0x208B37 <- Loading the coin counter address into R0
LDRB R0, [R0] <- Loading a byte (coin count) from address in R0 into R0
CMP R0, #0 <- Comparing R0 to 0
LDREQ R0, =0x02115AAC <- If they're equal, put address of idle standing state into R0
STREQ R0, [R4, #0x980] <- If they're equal, put R0 into Mario's state field
LDMEQFD SP!, {R4,PC} <- If equal, restore R4 and Program Counter (i.e return)
B 0x21135C0 <- Jump to next

I got both this function's address and the idle function address by watching Mario's state field in memory (Player address + 0x980). Death state is at 0x990.

And, uh, I meant that the function you found wasn't the jumping function. It seems to actually be what sets Mario's jump height or something, and it's called every frame.

Most of the code that makes up sprite 125:

bool Class229_ExecuteState0(Class229* class)
{
	0x2185EBC(class);
	0x209ADB0(class, 0);
	return 1;
}

void 0x2185F30(Class229* class, unk, unk1)
{
	class->unk3FC = unk;
	
	int something = (0x2186634 + ((unk<<3) / 4) + 1);
	int somethingelse = *(0x2186634 + ((unk<<3) / 4));
	
	class->unk3F4 = somethingelse;
	class->unk3F8 = something;
	class->unk400 = 1;
}

void 0x2185EBC(Class229* class);
{
	if (!class->unk400)
		{
			u32* pointer = (((class->unk3F8 >>> 1) / 4) + class);
			
			if (class->unk3F8 & 1)
				{
					u32* pointer2 = *pointer;
					u32* pointer3 = (*pointer2 + *class->unk3F8);
				
				}
			else u32* pointer3 = *class->unk3F8;
			
			pointer3();
		}
		
	else 
		{
			Similar jump as above;
		}
}

bool Class229_LoadFiles(Class229* class)
{
	return 1;
}

bool Class229_onDelete(Class229* class)
{
	return 1;
}

void 0x21860F0(Class229* class)
{
	return;
}

bool Class229_OnCreate(Class229* class)
{
	class->direction = (class->spriteData >> 28) & 1;
	class->scale.x = 0x1000;
	class->scale.y = 0x1000;
	class->scale.z = 0x1000;
	
	class->unk40C = (class->spriteData << 4) >> 28;
	
	if (class->unk40C == 0) class->unk40C = 1;
	if (class->unk40C > 4) class->unk40C = 4;
	
	int TempUnk40D = ((class->spriteData << 8) >> 28) & 0xFF;
	
	if (TempUnk40D == 0) TempUnk40D = 1;
	if (TempUnk40D > 3) TempUnk40D = 3;	
	
	class->unk40D = (TempUnk40D - 1) << (TempUnk40D - 1);
	
	if (class->EventIDField2 == class->EventIDField1)
		{
			if (!IsEventActivated(class->EventFieldID2) && !IsEventActivated(class->EventFieldIDw))
				{
					class->unk404 = 0;
					0x2185F30(class, 0, ActivatedEventsBitmask);
					*20CAC9C = -class->unk40D & *20CAC9C;
				}
		}
	else
		{
			class->unk404 = 3;
			0x2185F30(class, 2, 3);
			*20CAC9C = -class->unk40D & *20CAC9C;
		}
	
	class->unk3B4 = 1;
	return 1;
}

What does it do?
Well, uh... it sets some level params on event, it seems. No idea what those params do.
There are three nybbles it references: Nybble 5 which changes the field usually used by other sprites for direction, Nybble 6, which has range of 1-4 and Nybble 7, which has range of 1-3.

There's more code to tackle here, which I'll do later.
