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

1. Download the latest .vpk from Releases.
2. Transfer the VPK to your PS Vita.
3. 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
