Whenever I launch SNEmulDS (which btw I downloaded from GameBrew) an error shows:
FS initialization...
FS failure, continue anyway...
It then launches into the app just fine, but no ROMs appear when I go to the select ROM area.
I have tried keeping the ROM inside a folder on the root of the SD...
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
