trying to change the palette used by gameboy advanced games in mgba but can't figure out how to do so

There are 32768 different colors a GBA can display. There is no way to manually change them directly, but you can adjust them using shaders. There are sliders for saturation, brightness and gamma that you can play with in the settings.

is there a way to make a custom shader that targets specific colors to change them?

You'd have to write it yourself, but yeah. It's just a fragment shader as per regular OpenGL.
