How to switch from SX OS > Atmosphere or Atmosphere > SX OS without payloads

So I was on SX OS but wanted to play the latest Dreamcast emulator Flycast which only works in Atmosphere, so I found a way to switch back and forth through homebrew. I am doing this on latest fw 9.0.1 so it should work on any firmware.

You need
Fusee-STARTER https://github.com/Thomleg50/fusee-starter/releases/
Argon-NX https://github.com/Guillem96/argon-nx/releases
Atmosphere files and patches https://github.com/Atmosphere-NX/Atmosphere/releases https://gbatemp.net/threads/i-heard-that-you-guys-need-some-sweet-patches-for-atmosphere.521164/

Put Fusee-STARTER-1.0.1.nro in /switch folder
Put argon folder on root of sd card and argon-nx.bin goes in root of sd card
Put Atmosphere on sd card and the patches go in the same folder and will overwrite some file(won't cover this in detail here as it's covered other places)
Make a copy of your fusee-primary.bin and put in bootloader/payloads
Make a copy of your payload.bin from SX OS on your computer and put it in /argon folder

When you run Fusee-STARTER in homebrew you can now select fusee-primary.bin (or Hekate if you want to chainload) that gets you to Atmosphere from SX OS, if you want to go back just choose Argon-NX in Fusee-STARTER and it will boot SX OS. Done. If docked you can switch back and forth without getting up.

There may be other ways to accomplish this, that's fine. This is just the way I did it and will continue to do it.

By the way I've been using HekateBrew for over a week now and it's indeed the best solution (in my opinion) to achieve this and it definitely does support controller input so you can easily jump between any CFW from your couch while keeping the Switch docked which is awesome and just super easy.

Since it's using the hekate_ipl.ini * just make sure to have everything you want in there.
Simply add payloads to it with the payload keyword like this:
Code:
[SX OS]
payload=bootloader/payloads/SX_OS.bin

[L4T Ubuntu]
payload=l4t-ubuntu/coreboot.rom
(obviously make sure those payloads are in the given folders and named like that)

* you can still launch payloads manually from within the app that are not defined in hekate_ipl.ini though.

Thanks for your tipps ^^
Is it still the best now with FW 9.2.0 ?
I'm planning to switch between SXOS and Atmo, just for RetroArch/Flycast at the moment.
SXOS should be my main CFW but I want to be able to start Atmo out of an app.
I used the PayloadLauncher for using Lockpick RCM, would it work with this app aswell?

It should. Didn't test a while tbh since I've got everything I need in Atmo the last couple of months. :P
