The multi-platform open-source PlayStation 3 emulator RPCS3 continues to receive new feature updates more than nine years after its first debut. While there are still many titles that are not supported by the C ++ based emulator, the developers continue to optimize some exclusive PS3 titles that have not yet found their way to newer consoles. Being able to experience Demon’s Souls online multiplayer can be a good way to pass some time until Sony and Bluepoint release the highly anticipated Demon’s Souls remake on PlayStation 5. It’s worth noting that this online multiplayer build for RPCS3 only works for two games right now: Demon’s Souls and Bomberman Ultra
No, your eyes don’t deceive you! For the past year, developer GalCiv has been working on a private PSN server replacement called RPCN. This is a free and open source private server that can serve as a PSN written in Rust.
This server code, along with the large number of improvements to RPCS3, allows users to play in multiplayer and co-op modes in games that do not require or already have a custom server in addition to PSN. An example of this is Demon’s Souls, which now fully operates in multiplayer with RPCN as the private PSN server and DeSSE (by ymgve) as the private DeS custom server, with every function intact.
However, it should be noted that RPCN is far from finished, so currently only a very small number of games are working. In our current tests, Bomberman Ultra and Demon’s Souls are the only ones that work reliably, but hopefully the community will discover others that work well too! To learn how to configure RPCS3 to connect to RPCN, see the pull request for this feature: https://github.com/RPCS3/rpcs3/pull/8663
Currently, playing online requires a preview build available through this link (see the top one in the list)
If you want to host your own copy of RPCN, the server code is available here: https://github.com/RipleyTom/rpcn
If you want to try out RPCS3 for yourself, you can follow the quick start guide here. You need a 64-bit processor with at least 8 GB of RAM and usually a recently released AMD or Nvidia Vulkan compatible GPU to emulate the cell processor based PlayStation 3. The quick start guide also covers dumping your own PS3 discs using a PlayStation 3 with custom firmware or a supported Blu-ray disc drive on your computer.
