# Demon's Souls — PS5 emulator

Stable remake verification. Quality mode at 4K is the reference configuration.

## Facts (2026-10-13)

- **Rating:** Stable
- **Reference:** Quality mode, 4K where GPU allows
- **Firmware:** Official PS5UPDATE.PUP required
- **Library:** Own your copy; 400+ titles indexed

## Verification result

Demon's Souls is rated Stable. Archstone runs and boss arenas complete at the quality preset, with 4K holding on recommended hardware. Confirm headroom in [GPU and VRAM](/hardware/gpu-vram) before enabling it.

Latency-sensitive parries verify best with a wired DualSense. Setup is in [DualSense setup](/protocol/dualsense-setup-pc).

## Recommended settings

- Quality mode first; cinematic mode only on recommended-plus GPUs.

- Frame cap on; VRR displays should still cap at the title limit.

- Rebuild the shader cache after major builds — see [Shader cache](/reference/shader-cache).

## Setup sequence

1. [Download Meridian](/download) and finish [Boot system software](/protocol/boot-system-software) checks.

2. Install the official PS5UPDATE.PUP from Sony's system-software page with File then Install Firmware.

3. Index your owned dump per [Index your library](/protocol/index-your-library).

## FAQ

### Is Demon's Souls Stable?

Yes. Quality-mode runs complete end to end, including boss arenas, on the reference configuration.

### Why does 4K dip in one archstone?

That area is VRAM-heavy. Drop to native 1440p or close background apps; see [GPU and VRAM](/hardware/gpu-vram).

### Wired or wireless controller?

Wired DualSense over USB for parry timing. Bluetooth adds measurable latency.
