[Operyl]

Nope. It contains AOSP code (which started the rumor mill that it was Android) but it was not. It also contains some code from FreeBSD, which similarly sparked the rumor that it was FreeBSD, but alas it isn't. I spent a good amount of time in the early Switch days picking apart the operating system.

Here's a good wiki with a ton of information on the kernel/os: https://switchbrew.org/wiki/Main_Page

EDIT: Here's some AOSP usage: https://switchbrew.org/wiki/Nvnflinger_services https://switchbrew.org/wiki/Display_services and apparently some AAC codec code.
