mmm, i can help . the transformation sounds must be named "trans" and "trans2" for them to work.
trans is for the 1st long transformation, trans2 is for the other not as cool ones.
note that the "scream" sounds are for the end of the transformation, i.e AHHH!!!*energy sound*. that kinda thing.
Thats because they need to be coded a certain way, I can't remember what the code was... They had to be like 22000 hz and 16 bit mono for a format but im not sure... I am having the same problem right now with my kid buu pack. HOPEFULLY Mr. Satan of former ph34r will come and tell us since hes the one who told me before.
