However, you can not use CD images on PCSX so you'll have to burn them to disc first. 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. Created by Linux, PCSX is an emulator for the first PlayStation games that allows you to use CDs from the legendary Sony console on your Mac OS X.
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.
