I made a thing that edits saves. This only works on Fire Emblem Fates.
Currently, I am not actively working on FEFTwiddler. I may return to it someday if I decide to play Fates again. In the meantime, it's open source, so you guys are welcome to fork it and make unofficial releases if you want...
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
