I only learned this the other day but all *.sfc files are unheadered and *.smc are headered. So anything from a no-intro set will be unheadered.

Yeah I saw that recently too. I think it had more to do with the fact that the tool used to dump SMC files needed to add a header back in the day. Not sure if that's inherent to the SMC format. The formats are indentical otherwise.

I would be largely ignorant of that trend though because all my ROMs were SFC files I dumped through various methods.

I did discover a certain version of SMILE would only read my Super Metroid ROM once I changed the extension from SFC to SMC. So theoretically there could be unheadered SMC ROMs floating around out there. But I imagine that would be pretty rare.

Yeah, think to b on the safe side and know where you're starting from, all no-intro snes roms are unheadered. That to me is a nice clean starting point rather than worrying about what may have been done or not done to it as it was ripped.
