Whether these emulators support operating systems for these consoles is unknown; it must be looked into further. Consoles without meaningful OSes are not included.

This device runs an operating system which is known to emulate various devices with EOPs. See the AmigaOS, DOS, MSX, NEC PC-9801 series, and SHARP x68000 series pages.

L4T Ubuntu bootstrapped port.

https://fluxcoil.net/wiki/hardwarerelated/nintendo_switch#installing_fedora_32

L4T Ubuntu is a version of Linux based on nvidia's linux for tegra project

This appears to be the premier linux distribution for the Switch, being tailored for the console.

https://gbatemp.net/threads/l4t-ubuntu-a-fully-featured-linux-on-your-switch.537301/

Android 10 port is the most recent of the two, obviously. 8.1 is listed for posterity.

Not much to say about this, but there is a 4.1 exploit, and a 4.9 nvidia based fork.

a multi-purpose file manager

Not really an OS, but still provides a certain functionality not seen in the stock OS.

https://github.com/joel16/NX-Shell/tree/next

Does not appear to be a bootstrap, but has similar support as Debian.

They ported the mainline 4.16 kernel to the Switch

Based off the aforementioned 4.1 kernel by f0. Certain things are functional, while others are not. It’s probably not the best of the distributions available, but it’s still available.

This doesn’t need demonstration. Very simple, but an interesting code achievement.

Made pointless by the updated L4T-based distribution, but is worth listing anyway.

This may be only available to Microsoft employees, so they need to have something “revealed”.

simply opens up the fully enabled web browser

Uses the exact same browser as above, but unlocks functionality and convenience.

A classic trick, used to access a barebones browser on several systems.

I need finishing

There are three versions of this console, arranged chronologically.

RECOMMENDED OVERALL (get a V1 revision for EOPs)

The original Switch, and thus far, the only Switch that can be conceivably hacked without significant difficulty.

LOWEST PRICE

A Switch that has been shrunken down and turned into a portable-only system.

RECOMMENDED OVERALL (just for gaming)

Touted as a hardware upgrade, the OLED Switch barely qualifies as a proper “version” instead of a revision.

There are two revisions within the Switch (original), and XYZTEST revisions within the Switch Lite and Switch (OLED).

RECOMMENDED OVERALL (for if you want EOPs!)

BEST RELIABILITY couldn’t be assigned.
