I'm not exactly an expert on ripping but I think trying to open the files and check what they are would be a good move (if you haven't done that already and its possible)
Handing the file off to someone else could also be a good move, sorry I can't help as much as I would like to but I don't...
I may try the new ram site, and download more RAM to my Switch. Not sure if ddr3 is the right ram
for it tho. Edit- no it uses floppy Ram, just like @AncientBoi
