Just find a convertor, or hell, make one perhaps? I don't know your skill level, but between 3D printing or cannibalizing the parts are out there. The SFC library is awesome, and yeah I do have a SD2SNES but actually owning something you care about makes you use it, not flip through them like pages in a comic book. Last time I did it was when importing games were cheap and complete as it was before paper was something to hang someone over like a noose for extra.and I'm trying to get rid of more and more and adding like a couple dozen games defeats that purpose.
In all fairness though, it's like 50/50 bitterness and taking up space as the negatives. I kind of miss my old SFC collection but it's a rabbit hole I've put off like 5+ years now not diving back into.
