Editing Palletes with Hex Below I am going to explain how to edit palletes using hex without the use of any utilies at all. I got the below information while restoring my palletes due to the hack crashing. Now lets get started, shall we? OK now to edit palletes you'll need to know the locations of them in the ROM. (I obtained the below using Hivepal). If you need to know the left is pallete name and the right is the offset of the pallete.

Now to exlplain how to edit: First off leave that 0 there as the very first nibble on EVERYTHING! the last three nibbles are used as the RGB values. Now the higher you go the brighter the color. Like 0EEE would make a grey color 0000 would make black. 1EEE would most likely crash the ROM. Now if you use 0333 or 0111 it also won't work. You can only use even values. Even values are 0, 2, 4, 6, 8, A, C, and E. 1, 3, 5, 7, 9, B, D, and F don't work.Now when you reach the end of a pallete the bytes should be 0000 0000. Edit no further! If you edit any further than that you will be editing another level entirely. Now I'll say one more thing before you go away with new knowledge and start editing palletes. Now I'll explain what every nibble is. The first (should be 0) is I've no clue, the second is red, the third is green, and the last is blue.
