You cannot have both latest firmware Atmosphere + SXOS on chipped Mariko.
Upgrading Mariko sysNAND to 12.0.2 and beyond will break SXOS working emuNAND for good.

My son's Switch is a Mariko w/ Sysnand 11.0.0 and the latest Atmosphere + SXOS work fine. The only limitations for Mariko switches are you can never update your sysnand beyond 11.0.1 and you can't use any of the dual boot setups that use the RCM payloads. Updating Atmosphere's emuMMC to the latest firmware version also works just fine.

I did some tinkering here... Don´t know tour specifics but may help you
Haven't looked over whatever has been discussed but if that's some sort of guide please make sure to mention whether or not if it's for Mariko or Erista switches. What works for Erista does not necessarily work with Mariko switches especially RCM payloads.

Did you already updated your Mariko AMS Emunand to latest FW? Then is SXOS still run on emunand/sysnand afterwards?

I had Mariko FW 11.0.0 sysnand previously, and used to play AMS & SXOS on SYSNAND by swapping SD Card. Then I tried dual boot tutor from someone, with option AMS on SYSNAND & leave SXOS on Emunand. It works but with manual replace boot.dat, doesn't work with sxos boot.dat then payload->hekate->launch-> sysnand nor emunand (to open AMS). IT WORKS ONLY IF YOU REPLACE BOOT.DAT WITH AMS BOOT.DAT (only 10 kb size instead).

Then I tried to update my sysnand AMS to FW 13.0.0 by using Daybreak, wonder if I can have Bluetooth audio function and XCI benefit on the otherside. The result, only AMS running on both sysnand & Emunand. SXOS leave blank screen after use its boot.dat, I haven't tweaked with hekate.ini (will let you know I want to and I had done). Maybe somebody can try this too and find the solution for having those goddamn feature (Bluetooth & XCI, even you're not caveman you definitely want it)

@raging_chaos Please let me know if you updated the AMS emunand to FW 13.0.0 with your AMS sysnand leave at FW 11.0.0.
This is the snapshoot of my research.

IT WORKS ONLY IF YOU REPLACE BOOT.DAT WITH AMS BOOT.DAT (only 10 kb size instead).

AMS does not have a 10kb boot.dat , that is SX's boot.dat from SX Gear. You need SX Gear's boot.dat to boot Hekate/Atmosphere. You need SX Core's boot.dat to boot into SX Core's OS. You cannot setup dual boot on Mariko systems at all with just one boot.dat and chain loading through Hekate. Every post you see where it's working is because it is an original RCM Erista v1 Switch. Mariko cannot load RCM payloads, you will never be able to dual boot the way you have been reading. Manual swap of the boot.dat file is the only way unless you write homebrew application to swap the dat and shutdown the system.

As for your second question FW 13.0.0 is working just fine on the Mariko Switch with SX Core and I can still manually boot into SX or Atmos.

I did downgrade firmware on SYSNAND from 13.0.0 to 11.0.0 but SXOS still couldn't run, both on sys nor emu.
Tried Stardust and hekate.ini still shows blank screen. But AMS run smoothly with notice on boot the device took longer (about 1 minute) to show first boot logo (blue led light blips until switched to green). I think it's time to forget SXOS on this device forever.

There are custom boot.dat files. One that boots atmo. Supposed to work on mariko too..

You can keep sxos for just usb loading even on mariko....you can have seperate emunands. Seperate cards or 2 on the same card.

    I mean, if no-one can buy a PS5, and thus is stuck with PS4 (Pros), then companies would still see some profit from developing PS4 games with PS5 upgrades; meanwhile, if they developed a PS5 game, then everyone who can't get that console won't buy that game, especially at launch.
