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. BlissOS is an emulator that runs on Android Oreo and above.-It has two methods of installations, VM Install, and USB installation.-It used a virtual machine to function as an android emulator for your PC, although by using a USB stick it can also flat run on a PC. 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.
