NX-Shell VS TegraRcmGUI

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.

You're gonna want to use this in conjunction with the proper payload associated with how you modded the switch.

The program you'll need is TegraRcmGUI, but it requires a driver install. You might be able to do this on the computer - it worked for me at the hotel I stayed at last, but that was in Wisconsin.

Go to TegraRCM GitHub page and below assets click on "TegraRCM......installer.msi" it will download, install it, open it from desktop, go to settings tab and try installing the drivers again.

And no you don’t need a dongle. It’s for convenience. You can simply plug your switch into your pc via usb c - usb c (or usb a to usb c) and run this https://github.com/eliboa/TegraRcmGUI

You can find it here. https://github.com/eliboa/TegraRcmGUI

TegraRcmGUI has the ability to mount the SD card in your switch while connected to the PC you can then transfer all the files to it normally

I notice on the git hub that there is a TegraRcmGUI_v2.6_portable.zip that I assume is for an RCM loader but I am unable to find a proper tutorial on specifically Tegra. I really want to convenience of booting my switch mods without having to plug it into my computer every time.

https://github.com/eliboa/TegraRcmGUI/releases it a program that use to inject payload on to switch to run cfw

I use TegraRCMGui to inject the payloads, it has a helpful little picture to tell when your switch is detected.
