I have been trying to no avail to have the japanese voices in the english version of the rom. I tried unpacking the rom, copying over the sound.sdat file from the japanese version into the english sound folder then compressing it to have it freeze before even the first copyright screen shows. I know theres a patch to change the intro of the game, but what i want is also the japanese voices , like for example, when gokuu jumps over a hole he screams something in japanese while in the english version he just lets out a muffled out groan. The strange thing is that the above method works in no$gba but not on the ds. I remember reading somebody's post saying he managed to fully undub it but he did not state how he did it. Can somebody who knows how to do it please guide me?
