Why wouldn't joshw host ncsf? E.g. spc.joshw.info already hosts snsf despite not being spc (and different other chiptune systems added vgm despite that being superfluous), just include the differing format into the file name.
I will mention, as far as the tools for making NCSFs goes, I did find that the functionality to strip excess banks and waves breaks a few games, notably Mega Man Zero Collection breaks due to missing banks/waves. I haven't had a chance to look into why, though.
As far as hosting NCSFs goes, I have been toying with the idea of hosting them on an external host from my own server, but I haven't gotten around to looking for a good host for that yet. Ideally it would be a host that lets me use them primarily as file storage and has PHP scripting support. Although, I'm not against seeing them up on joshw's site as well.
If anything, there are a few sets on joshw already. Only issue is they aren’t labeled [NCSF] so it’s just mixed in with the rest. Most notably among them is Diddy Kong Racing DS.
@bx - Just did a search through the files database, found 64 sets containing an ncsflib file. If you don't mind I'll later rename all those sets to include [NCSF] in the file name.
I think I may have already asked this before but just for consistency's sake, should I upload the 2sf of DKRDS? I've ripped it and it sounds perfectly fine but no one ever uploaded it for some reason.
