Naturally, there are plenty of ways around this problem as with all things in computer science. We explored some of these approaches in early 2024 mainly to achieve a proof of concept. The first one was easy – if we provide a minimal stack for every function call and mimic x86 behavior. We keep the frames themselves stackless but track the previous call address and reload it to unwind. Unfortunately, this doesn’t work reliably since the basic blocks assume all stack space is scratch and will clobber the return address every once in a while leading to random crashes. Several other variations of this were attempted including reclaiming some registers for a shadow call stack pointer. They all work, but have different upsides and downsides. For example, some of them required modifying LLVM to accommodate RPCS3’s JIT architecture. Which wasn’t ideal as it required us maintaining a fork of LLVM. Another quick solution is to just replace all returns with a far jump to some host gateway that fixes up the register state and we can exit. This also proved challenging since our JIT blocks can loop between blocks and do recursion. The performance hit became too high for such a strategy to work.
The project is currently maintained and organized by a unique cast of characters, all with meaningful roles to contribute to different aspects of the project. Whether it's working on the emulator directly, coordinating community efforts or even keeping this very website current, everyone plays a role that adds to the bigger picture.
Internal team members aren't the only contributors. A lot of the progress made in making PlayStation 3 emulation possible on PC is thanks to the many developers we've received contributions from in our GitHub community. While many developers do come and go, we do welcome anyone and everyone who is interested in improving the codebase.
Before creating a new game page, please read the requirements page carefully. If you're sure the this particular game does not have a game page already, you can create the page by entering the game title in the textbox below:
RPCS3 requires the PlayStation 3 system software because it contains dependencies and proprietary libraries for the emulator to function. If you are running Windows, the Microsoft Visual C++ redistributable is required - Linux, macOS and FreeBSD do not require it.
In its current state, RPCS3 does not support reading game data directly from PlayStation 3 format discs. PlayStation 3 discs are formatted in a very special way that can only be read with an actual PlayStation 3 system, or a compatible Blu-ray drive from select manufacturers. For more information on what Blu-ray drives are capable of reading games, please refer to the Quickstart Guide .
Note : Remember that files need to be named the same way as on PS3 and in WAV format. More info can be found here
Our developers are pushing the very boundaries of PlayStation 3 emulation. Our rapid progression would not be possible without our contributors and Patrons. Our patrons not only keep us motivated, but keep our lead developers working on the project full time.
