Sony released the PlayStation Classic, which is a smaller version of the console that comes preloaded with 20 games on it. It makes a great little Christmas gift and what I found intriguing is that it’s definitely built on free/open source software, check out the Ars Technica article for more info on that:
PlayStation Classic uses the open source emulator PCSX ReARMed to recreate its selection of 20 classic games. Kotaku’s recent hands-on report with the plug-and-play HDMI system noticed an on-screen menu listing a legal license for the emulator.
ReARMed is a popular, modernized branch of the original PCSX emulator, which was actively developed from 2000 to 2003 for Linux, Mac, and Windows. A new branch called PCSX Reloaded picked up that development later in the decade, adding new features and fixing bugs and eventually leading to the ReARMed fork. The emulator supports network play and a “save rewind” feature that lets you easily reverse recent gameplay, two features that seem to be missing from the PlayStation Classic.
