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
- VitaRPS5-Style UI Redesign
- Modern card-based console selection interface.
- Professional PlayStation-themed color scheme.
- Redesigned PIN entry screen with individual digit display.
- Improved visual feedback and animations.
- Enhanced Console Wake Flow
- "Waking up console..." screen with animated progress.
- 30-second timeout with visual countdown.
- Automatic streaming start when console wakes up.
- No need to press X twice.
- Fixed Controller Input Issues
- Resolved race condition that prevented controller input during streaming.
- Properly separated UI and input thread buffer access.
- Controllers now work reliably during remote play.
- Improved Console Management
- Re-pairing now properly deletes registration data from storage.
- Better console name and IP display formatting.
- Circle button for cancel (PlayStation convention).
Installation
Download VitakiFork.vpk.
Transfer to your PS Vita (via USB or FTP).

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 (
- 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
- According to
