I got it working with the DSi version, I made a dummy 16KB save file and it worked fine, here it is
(It's not a txt, GBAtemp just disallows .sav files for reasons. Be sure to rename it to public.sav and put it into /title/00030004/4b435645/data if using the US version)
when i go into "/title/00030004/4b435645/data" it doesnt say that persay. It says "/title/00030004/53524c41/content". Is it still okay for me to put the file there?
