NX-Shell VS SysDVR

You might be able to access the save files using a Switch file manager like NX-Shell.

I recommend using a file manager like NX-Shell though since you can do all this directly from your switch without using a PC or phone. You can download it from homebrew store or https://github.com/joel16/NX-Shell/releases.

In addition to what others have said, if you really have no other options: https://github.com/joel16/NX-Shell

So I'll repeat my suggestion. Clean up the files using NX-Shell. Presumably you don't have a Windows PC handy or else you would have already fixed it, so there's a solution you can do right on the Switch itself.

NX Shell says it supports extracting zip archives - https://github.com/joel16/NX-Shell/releases

Hell yeah there is bud! You've got a few options, you could use NX-Shell which is a file browser found here or can be found on the homebrew App Store, second you could use Hekate and put your system into USB mode then connect to the system with your computer via USB although it sounds like you want to avoid your PC so the first option may be best.

I wonder if instead of the WiFi we could use the usb-c port and stream over it just like it is done in Sys-DVR (https://github.com/exelix11/SysDVR) on hacked Switch. That would make the MM/MM+ even more amazing!

SysDVR

SysDVR is the homebrew you want.

Not with Moonlight, but withSysDVR

Theres a Mac os version of sys dvr https://github.com/exelix11/SysDVR/wiki/SysDVR-Client-setup

Sys dvr - if you don't have streaming card, you can use it for streaming from usb to pc

You could use SysDVR but you would need a laptop or your tv would need to be able to work with rstp somehow. If you want 60fps then use this https://github.com/exelix11/SysDVR/issues/147

Sys-DVR A sysmodule that allows recording of game footage in most games. Has a configuration NRO, patches to try to force-enable recording in some games, and a client-side program to manage the capture process on your computer.
