Submitted one cover, and I'm trying to submit two originals; one older one and one newer one. They are two separate files, and I can't seem to find a way to combine them, so I'll probably have to submit two different nsf's
If you used FT to compile them, then you could just import them using rainwarrior's tool and them put both FTMs together and re-export. You could even do this if you used another compiler but your NSFs are compatible.
If you have songs in two different FTMs, go to Module -> Module Properties, click "import file" and include the instruments. jrlepage's method works too but probably takes a lot longer. This'll create a 2-track NSF.
I wouldn't do the NSF importer except as a last resort. Your file size will balloon, and it might not be completely accurate.
Do it Rushjet1's way if you can.
I assumed ArchJ had two NSF files and not FTMs since it wasn't mentioned in his post. For two FTMs, of course combining them via Module Properties is faster and more efficient...
Yeah, it's preferred that you do so. All names and copyright info will be removed from the NSF during the voting period, then when the results are announced a new pack will be released containing the original NSFs with all meta data intact.
