The emulator was first able to successfully run simple homebrew projects in September 2011 and got its first public release in June 2012 as v0.0.0.2.
The developers initially hosted the project on Google Code and eventually moved it to GitHub on August 27, 2013. Despite the general idea that the complexity of the PlayStation 3's Cell architecture would prevent it from being emulated', RPCS3 was started on May 23, 2011, by programmers DH and Hykem.
