Well, my "SNES StarterKit" uses WLA-DX, but I wouldn't consider it a tutorial.
It includes a HiROM and LoROM example, and uses some macro features. I haven't updated it in quite awhile though ... so there isn't any demonstration of newer WLA features. Also, I don't include any sound code, so there are no SPC700 examples.
I haven't done any work on the NES, but with all those different mappers, I'd think setting up different rom regions in WLA's memory map could come in handy if used correctly. But, I don't really know much about the NES ... and I'm not sure where to obtain any NES examples in WLA-DX either. So I can't really be of much help here. Sorry :(
