A fatal error ocurred when running Fusee. Unable to identify the package! Press power to reboot

[Gabo_1457]

Greetings people! I have a problem here hehe. I recently purchased a 1TB SD card for my nintendo switch. The brand is Lexar. I already formated to FAT32 and I coppied all the files that were on my previous sd card to the new one. For some reason, I got this error when I boot up the emunand: A fatal error ocurred when running Fusee. Unable to identify the package! Press POWER to rebootI did the changes for atmosphere here to get the last version but still not fixing that error . What could it be? Hmm

Hi I just modded my switch for the first time and emunand, atmosys CFW, and stock sys will not work for me I am getting the same type of errors as the person who started this thread. My switch is in Ver 20.0.1 (Latest update) and the rest of my files (Atmo, Fusee, Sigs, etc.) are all the latest versions aswell. Do you know what could be the issue? It will not launch anything not even fusee.bin config.

Hi, I just modded my switch for the first time through this guide () and am having the same issues. My emunand, atmosys CFW, and stock sys will not launch. I get an error for all three. I also cannot launch from fuse.bin config. My switch has the latest update sadly (20.0.1) so that might be the issue but I am not sure as this is my first time modding a switch. My atmosphere, sigpatches, etc. are all the newest versions.

It's due to the latest update (v 20). It has rendered all of those files incompatible. You will have to wait for all those things you mentioned to be updated for the latest version. No ETAs.

Do you mind replying to this post when the latest versions come out? I don't know where to find that stuff but it's easy for me to check this everyday

No one knows. The authors of the respective files are already aware of the latest update and are in the process of updating their own works, but they haven't given any estimates.

Just check back periodically with the various sources you got your files from, which I assume to be from the google doc linked in that video description?

Okay yes I will check those then, thank you for your help!

switch version is 20.0.1

nintendo did a 2nd update, cause people with mod chip switches and unmodded switches were getting their consoles bricked by the 20.0.0 update
