EmuFive brings PS5 games to PS4, with God of War: Sons of Sparta at 40 FPS on the Pro
The emulator needs a jailbroken console and patches missing CPU instructions, yet the Jaguar chip still holds back demanding 3D titles.
Key takeaways
- EmuFive is a PS5 emulator for the PS4 built on PS4 Multiboot and based on KytyPS5.
- God of War: Sons of Sparta reportedly runs at 40 FPS on the PS4 Pro.
- The PS5 version of Hollow Knight: Silksong also runs on the emulator.
- The PS4's Jaguar CPU lacks AVX2, FMA and BMI2 instructions, which KytyPS5 patches.
- Complex 3D PS5 games are expected to run at unplayable framerates on the PS4.
A PS5 emulator on older hardware
An experimental emulator called EmuFive is running PlayStation 5 games on the PlayStation 4, according to Wccftech. The project is built on PS4 Multiboot and requires a jailbroken console. It is based on KytyPS5, an emulator that rewrites PS5-only CPU instructions into game code.
Wccftech reported on 11 November 2026 that God of War: Sons of Sparta runs at 40 FPS on the PlayStation 4 Pro through EmuFive. The PS5 version of Hollow Knight: Silksong also runs, the report said. Other games are still being tested, and their performance has not been disclosed.
Why the Jaguar CPU holds it back
The PlayStation 4's Jaguar CPU lacks the AVX2, FMA and BMI2 instructions that KytyPS5 expects. The emulator has been patched so those instructions are replaced by code with the same effect.
That patch does not close the speed gap with the PlayStation 5's Zen 2 CPU, according to the report. Any complex 3D PS5 game that runs on the PS4 will likely do so at unplayable framerates.
Forward compatibility, not backward
Consoles usually offer backward compatibility, letting new hardware play older games. EmuFive works the other way, running newer software on older hardware.
Wccftech called the project interesting regardless of how the PlayStation 4 handles emulated PS5 games. The report said a major 3D game is unlikely to run well on it, but noted that development in gaming and emulation projects has been accelerated by AI.

Frequently asked questions
What is EmuFive?
EmuFive is an experimental emulator that runs PlayStation 5 games on the PlayStation 4. It is built on PS4 Multiboot, requires a jailbroken console and is based on KytyPS5.
Which PS5 games run on EmuFive?
According to Wccftech, God of War: Sons of Sparta runs at 40 FPS on the PlayStation 4 Pro, and the PS5 version of Hollow Knight: Silksong also runs. Other games are still being tested.
Why can't the PS4 run complex PS5 games well?
The PS4's Jaguar CPU is much slower than the PS5's Zen 2 CPU. KytyPS5 patches missing AVX2, FMA and BMI2 instructions, but that does not make up for the speed difference.
