In Emulators / NES ROMs

sorry for all the questions today. i have a recording project coming up

i need to know if theres a way to turn nsf files into .wav files. I'm specifically concerned about being able to convert 1 of the channels at a time and alone (i.e. square, triangle, DMC each to its own seperate wav)

if thats not possible then a regular wav conversion will work

I know Audio Overload allows such things, but it's a Mac OS application, I would assume there is an NSF player or an emulator out there with WAV logging, and to get individual channels, just turn the others off and log it.
