This version of Basilisk II is based on Chilly Willy's PSP port v1.1.1

Unsurprisingly, the Basilisk port to the Vita is capable of running several versions of the Classic Mac OS. Here, it actually specifies it’s 7.0.1-8.1, unlike some Basilisk II emulators which don’t clear that up.

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

There are complaints about retroarch versions above 1.8.x, beware!

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

This is a kernel plugin that lets you run Linux in ARMv7 non-secure System mode.

This project stunningly appears to be mostly dead. Some changes have been made, but the consensus puts this Linux port as being a lot less capable than even the 3DS port.

Another visually appealing OS from the Sony consoles, and one of the more feature capable ones that doesn’t feel completely sterile.

VitaShell is an alternative replacement of the PS Vita's LiveArea

A shell replacement that has a nice arrangement of functions, primarily things for a technical purpose, such as FTP integration.

It is multithreaded, so you won’t get stopped by a single screenshot

Self explanatorily the better internet browser for the PlayStation Vita, that’s a homebrew app. Apparently supersedes a prior homebrew internet browser in quality.

The simple browser preinstalled on the PlayStation Vita. Works alright, but it has been superseded by homebrew creations.
