Hi Luca,
The transfer function will crash if your data is not valid. Check if the
addresses match at the siocons. Try the VABtool to verify if the data is
valid. If data is valid, be sure the data does not cross the stack
(about 801f0000). If the tranfer completes you should hear a sample by
calling the SsUtKeyOn IF you turned on the mainvolume!

Hope this helps
Ivo
