VitaRPS5 is a fork of ywnico's Vitaki Fork, which itself is based on AAGaming's original Chiaki port Vitaki. This project provides PlayStation 5 Remote Play functionality on the PS Vita.
This is an enhanced version with modern UI, optimized performance, and quality-of-life improvements.
Features
- Modern UI — Card-based console selection, wave navigation sidebar, tabbed settings, PlayStation-themed design.
- Low-Latency Streaming — Tuned thread priorities, 500Hz input polling, optimized network buffers.
- Controller Customization — 3 custom preset slots, fullscreen interactive controller diagram with front and back views.
- Smart Connection Flow — Auto-discovery, animated wake-up with progress countdown, automatic streaming start.
- PSN Internet Remote Play — Sign in with PSN to stream from outside your home network via UPnP NAT traversal (works on most home networks; falls back gracefully on restrictive ones).
- Packet-Loss Recovery — Reconnecting overlay, automatic bitrate adjustment, seamless retry without crashing.
- Flexible Video Settings — Latency presets (ultra-low to max), fill/letterbox toggle, 30/60 FPS control.
- Full Control Support — All buttons mapped including L2/R2/L3/R3, touchpad, and motion controls.
Installation
- Download the latest
.vpkfrom Releases. - Transfer the VPK to your PS Vita.
- Install using VitaShell or your preferred installer.

v2.0.0
- Thread Priority & CPU Affinity Tuning
- Input thread priority increased to 96 (from default) and pinned to CPU 1 to avoid contention with media processing (
vita/src/host.c:1194-1195) - Audio thread priority set to 64 and pinned to CPU 0 for consistent audio mixing without dropouts (
vita/src/audio.c:144-145) - Video decoder thread priority 64 and pinned to CPU 0 for optimal hardware acceleration (
vita/src/video.c:691-692) - Result: Input processing now takes precedence over all other tasks, reducing controller-to-network latency
- Input thread priority increased to 96 (from default) and pinned to CPU 1 to avoid contention with media processing (
- Input Polling Optimization
- Reduced input polling interval from 5ms to 2ms - effectively 500Hz sampling rate (
vita/src/host.c:1203) - Adaptive sleep alignment prevents CPU waste while maintaining tight sampling
- Controller state changes are detected and transmitted 2.5× faster than before
- Reduced input polling interval from 5ms to 2ms - effectively 500Hz sampling rate (
- Network Receive Queue Optimization
- Trimmed Takion reorder queue from 128 to 64 packets on Vita builds to reduce buffering latency (
lib/src/takion.c:47) - Added overflow logging with rate limiting to monitor packet loss without spam
- Implemented automatic drop detection and recovery for degraded network conditions
- Result: Lower end-to-end network latency, especially on clean connections
- Trimmed Takion reorder queue from 128 to 64 packets on Vita builds to reduce buffering latency (
- Packet Loss Fallback System
- Automatic bitrate reduction when frame drops detected (Ultra Low → 800 Kbps emergency mode)
- "Reconnecting..." overlay with seamless resume instead of crashing to menu
- Keeps controller input flowing during recovery to avoid input gaps (
vita/src/host.c:1248-1252) - Up to 2 automatic retry attempts before returning to menu
- Video Pipeline Optimizations
- VBlank wait disabled during streaming to eliminate vsync latency (
vita/src/video.c:872) - Frame presentation uncapped for minimal display lag
- 30 FPS lock by default reduces bandwidth and decode workload (configurable to 60 FPS in settings)
- VBlank wait disabled during streaming to eliminate vsync latency (

- Input lag: <10ms (down from 20-30ms)
- Video decode-to-display: ~30ms
- Network RTT: Variable (depends on connection)
