I’ve been hearing a lot about how it might take over 10 years for emulators of the Xbox Series X/S and PS5 to be developed, and that they require really powerful computers to run. I find it hard to grasp why this is the case. From what I understand (and I could be wrong), the console OS operates in a virtual environment that thinks it’s on actual console hardware, sending instructions to the CPU. Since PC CPUs are built differently, those instructions need to be translated. But I’m not seeing why this is such a complex challenge…

On the bright side, emulators like ShadPS4 are already showing great potential and many PS5 games are just remasters of PS4 titles, which could make future emulation development a little easier!
Creating APIs and methods without existing references is incredibly challenging. Most tutorials don’t cover emulator development, so developers often have to rely on SDKs and make educated guesses about implementations, which can be really frustrating. I’ve never built an emulator myself, but as a programmer, I can tell it’s a tough nut to crack!
A powerful PC is necessary because you’re basically simulating an entirely different machine that’s also running under load. To effectively emulate a Series X, your PC must manage the operating system, the emulation software itself, and the game. This pulls resources from the same pool, like CPU threads and RAM, so you need plenty to keep everything running smoothly.
The whole translation issue isn’t straightforward. Not every instruction maps 1:1 between different CPU architectures. Due to differences in hardware design, some tasks might take multiple instructions to emulate. So when you’re running emulation, you might need a CPU that’s X times faster to achieve the same outcomes, depending on how the original instructions are structured.
While it’s true that modern consoles use x86 or ARM architectures, which is simpler than older designs, there are still significant differences. Consoles may have special APUs, while PCs might not use those configurations, resulting in slower memory allocations. Plus, it’s not just about translating instructions; the complexities involved can make it hard to get everything running perfectly. Even with 99% of the functionality working, that last 1% can cause critical failures.
It’s interesting to note that while emulation might sound easy theoretically, it highlights a programmer’s understanding (or misunderstanding) of the complexities involved. Just because it seems simple doesn’t mean it is!
