There's no officiell soundpak yet ...
goto
www.redsaiyan.net and download a new model with its own sounds ...
Or wait until my german soundpak is released
It'll come ... sure
My Opinion about voices:
I think a few voices should be the jap ones ...
A few the english ones ...
And a few odf the german ones ...
(jap: Gohan, Vegeta)
(english: Piccolo, Cooler last stage, Cell (all monsters), Krillin)
(german: Goku, Frieza, Chao Zu)
