Arne, first nice stuff thanks for sharing.
There’s one thing I don’t understand :
The file song in bytes in decimal is 35352892
As $DFF404 is in 32 bit that give use a length equal to 223169060
So why is $DFF404 value is decimal 4419111 ?
Even if the value is two words like on the Amiga that would give us 8832222

So what am I missing?
Thanks

  Hello Kamelito Loveless ,
  thanks for your detailed look!
  It's so in Stereo mode, the size is * 8 because it plays a pair of 2 samples each(rights lefts/left right)
