I’ve noticed that for the switch release, the NSP files are no longer available since 1.7.6.
When will it become available again? .nsp form is a huge help because they allow the switch to utilize more memory and run Mupen64Plus. It’s also valuable to run retroarch from the home menu and not having to run from the homebrew menu.
That, and it seems that earlier versions of retroarch don’t support controller input on the latest version of the switch.
