I never did manage to but in the No-Intro Ereader set you can find the save files in the Memory Dumps Zips. I.E. "Memory Dumps - Animal Crossing-e (USA).zip"
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
