sys-ftpd-light VS dbi

Try https://github.com/cathery/sys-ftpd-light. It's super convenient.

I recommend sys-ftpd lite (which runs in the background), https://github.com/cathery/sys-ftpd-light you need to edit the config.ini located in config/sys-ftpd/config.ini you can configure the user/pass or just enable anonymous:=0 then you can use a client like filezilla, winscp or windows ftp to access your switchs sd card with your switchip:5000 u/ToxiClay you should try this too.

yes you can use FTP, either https://github.com/mtheall/ftpd or https://github.com/cathery/sys-ftpd-light, you still need to transfer your files prior, also you can mount your switch via usbc cable using tegragui, I also believe there's a homebrew app that allows you to access the microsd card via usb cable https://github.com/retronx-team/mtp-server-nx i think

tried to make sys-ftpd-light function, but it still won't.

I would also reccomend you get dbi responder as your first app. It's MTP Responder option will let you access the switch from your PC which makes installing stuff later much easier. https://github.com/rashevskyv/dbi/blob/main/README_ENG.md I would link to the download page but it's in Russian.

Download the latest dbi.config and DBI.nro files.

You can use DBI for Force language per game.

Go to the latest DBI release.
