Palettes and Hex Editoring

[B-Run]

ASM is the only way to do this. There are only a handful of battle palettes, but with ASM you can point the script at the beginning of battle that loads the palettes to the same place the overworld palettes are (which keeps every existing PC palette working except esper terra, which you can reset), and then change the battle palette pointer table to reflect the palette you want them to use. It's not a particularly complicated ASM task, in fact, its a great beginners task and a good way to break open the concept of learning ASM. If you are interested, go over some hex tutorials in the tutorial section of the forum then come back here and I will give you the locations to find the code that needs to be altered.
