Ripping multiplayer GBA Sprites (Solved)

It Work's! Thank you so much Quick question: Can YY-CHR change the game's palette data?

Indeed. The easiest way is with the save state ( Palette/Load Save State). Play until the sprite is displayed and take a save state. Then load it with YYCHR and you will have the palette that was loaded in the ram when you took the save state. Not too sure if you can do it considering your multiplayer problem.
