1. I extract an image:

2. After editing, I insert it back and test the ROM.

The palettes have become muddled up, if you look at the mother logo and in general. (I know about the tiny graphical glitch).
How do I avoid this, as I still want to use NLZ-GB since it's my only good option of finding and hacking the graphics of Mother 2 GBA's title screen...
