stuff i've plotted in desmos

in some order idk

CIELAB nonlinearities

the two nonlinearities involved in (a scalar version of) converting RGB to CIELAB.

f(x) converts RGB to linear sRGB. g(x) is used in converting linear sRGB to XYZ. the black line is the combination of the two, not quite linear.

how to use:

these gameshark cheats will override the default save file with the debug save file. create a new file on the file select screen and it should create a debug save. note: this is probably the same as using map select.

info dump on the RNG in OoT and MM

if you find any discrepancies, please leave a comment or tweet at @antiformant.

the function itself

the random number generator in both games is an LCG:

	#!/usr/bin/env python3
	# find duplicate images given a hamming distance threshold.
	# employs dhash to do the heavy lifting.
	# doesn't recurse into "./_duplicate/" so you can dump things there if you wish.
	# dependencies: pillow, dhash

	import sys, os, os.path, pickle
	from PIL import Image
	import dhash

	(J 1.0)
	here's all the calls to 801008C0 when creating a save file,
	which in turn calls memcpy at 80092260:
	to: 801EF484; from: 801C1510; size: 00000028
	to: 801EF4AC; from: 801C1538; size: 00000022
	to: 801EF4D0; from: 801C155C; size: 00000088
	to: 801F07EE; from: 801C15E4; size: 00000002 # checksum
	to: 80506D30; from: 801EF460; size: 00003F50 # copy to buffer to write to SRAM

	same thing but with save context offsets and decompressed rom addresses:

	#include <stdint.h>
	#include <stdbool.h>
	#include <stdio.h>
	#include <string.h>
	#include <inttypes.h>

	typedef uint8_t u8;
	typedef uint32_t u32;
	typedef uint64_t u64;
