have same error, files are correctly dumped.
anyway to fix?
Edit:
i followed the "unbricking the nsw level" 1- 3 guides many, MANY times with everytime same result.
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
