If you use the deepsea aio, they have a payload that can fix quite a few things. Even "uninstalling" themes (I use "" because it's not un/installing anything. It's just copying files to the correct directory)
probably due to the button requirement. its set to disable the spawn by default till L+R are held and it will set a new spawn then return to default state. So just use the second 040A0000 line as a seperate code. cant guarantee but can try.
Yeah oblivionregin makes their codes on the actual hardware, the switch emulators (for one reason or another, im not sure) don't support all the code types that atmosphere uses. Eiffel2018 made some codes for yuzu/ryujinx but they're for 1.0.2
That's an old hekate_ipl.ini file. None of those options will work besides the one name fusee as long as you rename fusee.bin to fusee-primary.bin every time you update atmosphere. Fusee-primary.bin and fusee-secondary.bin haven't been used since...
Noexes just allows you to connect your switch to computer. Allowing you to use your switch and computer to make cheats for games. You don't need to delete breeze or edizon-se to remove it.
