OK, this is my first time doing this sort of thing. I have, as you can imagine, many questions.

1.) How do I convert a NFC file over to mp3?
2.) How do I spilt these files?
3.) How do I loop and fade them out?

Inquiring minds need to know! Thanks. ;)

1.) Do you mean NSF? (NFC is some weird Nokia Cel Phone file)
2.) Is this about Dragon Quest IV? If it is, I already posted an mp3 set in the dragon quest thread for you.
3.) Here is a loose tutorial that is for SPC, but it's the same process. http://forums.ffshrine.org/showpost.php?p=1365965&postcount=4
