Uhhhh, it says on nesdev that that NSF uses many "undocumented" features of the 2A03s sound hardware. How technical exactly is this? If they were undocumented are they still? Why won't it work on emulators? Is it because of timing or something....it did seem like a complicated song though.

And what about Skate or Die 2 the title theme? That was crazy! It all has some guy saying skate or die, but at each time he said it differently like. Was that all the same sample? And also the electric guitar with the dpcm channel was a playing at a whole mess of different notes and stuff. Now that was all done through $4011 manually....RAWly. And I heard it synchronized the rate of playback to $4011. Was that the change of notes and frequencies and why it suounded much different even though it was the same sample? Or was it different samples?

thx :)
