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 .vpk from Releases.
• Transfer the VPK to your PS Vita.
• Install using VitaShell or your preferred installer.

For usage please see Vitaki Fork.

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 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
• 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
• 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)
• Measured Impact
  • According to docs/LATENCY_QUICK_WINS.md, these optimizations deliver:
    • 20-40ms latency reduction (realistic estimate)
    • Input lag reduced from ~20-30ms to ~10ms (controller polling improvements)
    • Network handling optimized for both local and remote connections
• VitaRPS5-Style Interface
  • Clean card-based console selection with PS5/PS4 visual indicators
  • Professional PlayStation-themed color scheme (blues, whites, sophisticated grays)
  • Wave-animated navigation sidebar with collapsible menu
  • Individual digit PIN entry screen for console pairing
• Enhanced Console Management
  • Automatic console discovery on local network
  • Manual remote host configuration with static IP support
  • Console wake flow with animated progress and 30-second timeout
  • One-tap streaming start when console wakes (no double-press required)
• Settings & Configuration
  • Tabbed settings page (Streaming, Controller) with L/R navigation
  • 3 fully customizable controller preset slots (Custom 1, Custom 2, Custom 3)
  • Immersive fullscreen controller mapping screen with procedural Vita diagrams
  • Latency mode selection: Ultra Low, Low, Balanced, High, Max (targeting 1.2-3.8 Mbps)
  • Fill Screen toggle and Force 30 FPS option
• Controller Input Fixes
  • Resolved race condition preventing controller input during streaming
  • Properly separated UI and input thread buffer access
  • D-pad navigation no longer double-processes when nav bar focused
  • Focus manager prevents input leaking between UI zones
• Connection Reliability
  • Fixed instant disconnection bug from upstream
  • Console re-pairing now properly deletes old registration data
  • Remote Play crash/in-use detection with user-friendly hints
  • Improved error handling for network timeouts
• UI Polish
  • Fixed content overlap with navigation pill
  • Profile page layout corrected (Y=60 → Y=80)
  • Triangle icon in menu pill matches PlayStation conventions
  • 48px navigation icons with optional text labels
• Latency Breakdown (estimated)
  • Total latency: ~100-140ms remote (down from 150-200ms), ~50-70ms local (down from 80-100ms)
  • Input lag: <10ms (down from 20-30ms)
  • Video decode-to-display: ~30ms
  • Network RTT: Variable (depends on connection)
• Platform Constraints
  • PS Vita: 960×544 display, quad-core ARM Cortex-A9, 512MB RAM
  • Hardware H.264 decoder (SceVideodec) for video
  • vita2d for all rendering
  • Dual CPU cores: CPU 0 for media, CPU 1 for input sampling
• Chiaki Protocol Enhancements
