Fun, huh? Now recompile the rom by issuing this command:
ndstool -c JSS.nds -9 arm9.bin -7 arm7.bin -y9 y9.bin -y7 y7.bin -d data -y overlay -t banner.bin -h header.bin
From what I understand, all this does is create insignificant graphical glitches before a fight. Everything is more or less intact.
