Cross Platform
RetroArch
can run on the usual platforms like Windows, Mac OS X and Linux, but it
stands alone in that it can support far more platforms beyond just
that.
We
support operating systems that not even Microsoft and Apple themselves
support anymore, such as macOS X on PowerPC Macs, and RetroArch being
available on Windows OSes as far back as Windows 95.
On
top of all that, RetroArch also runs on iOS and Android for tablets and
phones, as well as on game consoles like PS3, PSP, PS Vita, Wii, Wii U,
Switch, and more!
