Great reverse engineering. Looking forward to seeing how helps homebrew in the future.

I have a patched switch on 5.0.1, does this mean there's no point in keeping an eye on https://pegascape.sdsetup.com/ anymore?

Nintendo will fight to make it illegal to hack systems here in America, just like it is in Japan.

I wonder what this site will become after that.

Fortunately, in some regards, the rest of the world is not like Japan and Nintendo doesn't have that much power out here. And this comes from someone who loves Japanese culture in general, who has been to Japan and has long time friends living there. I used to idealize it because of manga, anime and doramas, but for some real world stuff Japan is hell compared to most of Europe. Crushing bureaucracy, expensive healthcare, work, social relationships, corporate power and influence in politics, terrible court system... We have that, but Japan is on an entire new level..

Plus Europe has already passed laws on right to repair and is keen on expanding them, the RTR movement is rising in America too, so I think we are safe for the time being.

@SciresM man you might be our only hope as I dont see anybody else trying to meddle with sx core atm, please keep up awesome work you do with new switches also from what I understood, on xecuters code the are lying out of their ases, in their doc it says it is possible to run other payloads, I just dont find this appropriate after learning these things I wish some open source people make alternative to their modchip, I also wonder is it possible to enable sxcore to run payloads like unpatched ones?

With the discovery of the TegraRCM exploit that allowed homebrew enthusiasts to run unsigned code on it, Nintendo responded by releasing new Nintendo Switch units codenamed 'Mariko'. While at first glance this newer model is barely distinguishable from the older one (save for the flashy all-in-red box), it features a better battery life and slightly altered CPU instructions to help with power management and consumption.

However this was at a cost as the boot ROM bug that allowed homebrew enthusiasts and tinkerers to tamper with their switches was fixed for good. This of course upset many owners of the newer Switch iterations, and left people wondering whether or not they could ever enjoy homebrew on their 'Mariko' Switches in the future.

That future might not be too far away as developer @SciresM has successfully managed to dump the keys of the firmware on said units. In his YouTube video he showcases how this process was achieved:

Even if slim, these early developments show that there is a possibility of running homebrew on the Nintendo Switch 'Mariko' units, and getting TrustZone access on the system.

funny how he acts as if he found it himself. We all know he used a sx core chip.

Impressive video, didn't watch it all, didn't understand any of it. Hopefully some clever people will use it to make some cool things
