Hello, I was wondering if anyone could offer documentation on the simplest way to edit the palettes of GBA games? Specifically how people are able to make Color Restoration hacks, like these ones:
romhackplaza.org
romhackplaza.org
Where they can replace the washed out palettes of GBA games with more vivid, darker ones.
Specifically, I want to do this for Mario and Luigi: Superstar Saga. I know I just linked to a palette hack of it, but there are some issues with that mod I'd like to take a look at myself.
It would also be nice to know how to do this for other games. I've tried looking into it myself but there are so many tools to choose from and it's hard to know what the most intuitive method is.
Thank you for any information!
