PPSSPP, DuckStation and PCSX2 each emulate one system, while RetroArch is a frontend that hosts many emulators and game engines under one interface. Libretro publishes version 1.22.2 for Windows as a free download of 199.4 MB.
Who a single frontend for many systems suits
RetroArch fits people who want one place to run classic games instead of installing a separate program for every console. It also covers game engines and media players, so its scope reaches past emulation alone.
People who need a dedicated tool for a single system may prefer one of the listed alternatives, such as Cemu, BizHawk or DOSBox.
Shaders, netplay and runahead in practice
RetroArch's advanced features include shaders, netplay, rewinding, next-frame response times and runahead. It also offers machine translation and accessibility features for blind players.
Settings are unified, so you configure the program once and the choices apply across the cores. RetroArch can also run original game discs (CDs).
Size, licence and package details
The package is free and uses the GPL-3.0-only licence. At 199.4 MB it is a sizeable download for a frontend. The package identifier is Libretro.RetroArch.
An Android version also exists.

Is RetroArch safe?
RetroArch 1.22.2 is a 199.4 MB build that Libretro publishes on its own build server, buildbot.libretro.com. The GPL-3.0-only license means the frontend's source is open for anyone to review. A quick antivirus scan of the Windows download is still a sensible habit.
