Hacking Question Prod Keys on emuNAND

[MariusMoga]

Hi,

I have a Switch running emuNAND with firmware 5.1.0. I updated it with Choix from 3.0.1. I generated the Prod Keys when on firmware 3.0.1 and it looks like it worked also for 5.1.0 (at least on 2 NSP files I installed).

Now I am considering updating the emuNAND to 8.1.0 to install other NSPs as well. Do I need to re-generate the Prod keys after the update? I've read something with firmware 6.2.0 changing the way how they are generated but I didn't understood exactly all the details ...

Thanks,
M

You need newer keys for newer games. However you cannot dump keys with emuMMC, you can only obtain them from sysMMC.

Figured I would bump this because I was looking for this answer as well.

As of today (8 hours ago), you are able to dump keys from emuMMC. I can't direct link, but its on the Lockpick_RCM GitHub version 1.5.0

you use newer keys in one of two ways

1 you update the firmware to a higher version that has the newer keys you need

2 you run atmosphere using fusee which will automatically use all the latest supported master keys regardless of firmware version

note that games will break if you dont update your firmware, and the games require functions from newer sdk that arent in your older firmware. regardless of whether you use fusee to bypass firmware master key requirements or not
