The RPCS3 development team has recently added stable support for Arm64 on Windows, macOS, and Linux. This means that even low-end devices like the Raspberry Pi 5 can now emulate the PS3 with some compromises, such as a resolution of 273p, reminiscent of the PSP. However, games like God of War HD can still run, albeit with some issues. 2D games, on the other hand, work much better.
The native support for Arm on Apple Silicon, on the other hand, offers a significant performance boost of up to 100%. As a result, games like God of War III and Skate 3 can now run and play much better than on x86 emulation. Emulation of the PS3 on Arm is no longer theoretical, but a real and working reality.
The achievement of the RPCS3 team in making the ps3 emulator run smoothly on raspberry pi 5, apple silicon is indeed commendable.
