Roadmap

Moonlight PSP Roadmap

Current Status (v0.2.3-beta)

• Status: Active Beta — Streaming on real hardware
• Decode Pipeline: Dual-core OpenH264 (CPU) + VFPU color convert (ME), fully custom
• Protocol Stack: Custom RTSP/RTP/Control — no moonlight-common-c
• Streaming: 480×272 @ 30fps, ~13.8 fps measured on PSP-1000 (802.11b)
• Host Discovery: mDNS + subnet scan + multi-host pairing (up to 8)
• Error Recovery: Dual-mode watchdog, corruption gating, IDR exponential backoff
• Encoder Docs: AMD, NVIDIA, Intel, and software tuning guides published

Phase 1: Stability ✅ Complete

• Fix control stream connectivity (ENet replaced with custom Moonlight protocol)
• Stabilize RTSP handshake on real hardware
• Verify A/V sync over sustained stream sessions
• CABAC warning dialog (PSP requires CAVLC — CABAC supported but unstable)
• Dual-mode watchdog (decode hang + RTP stall detection)
• Reed-Solomon FEC with predictive burst loss detection

Phase 2: Optimization ✅ Complete

• OpenH264 software decode (ME hardware AVC abandoned — sceMpeg too limited)
• VFPU-accelerated YUV→RGBA on ME core (concurrent with CPU decode)
• PID-based adaptive bitrate controller
• Dynamic resolution scaling (4-step ladder: 256×144 → 480×272)
• Memory optimized for PSP-1000 32MB limit
• MS LED disabled during streaming (retail builds)
• ms0: write gating in retail builds (eliminates flash I/O stutter)

Phase 3: Features ✅ Complete

• Custom bitrate and resolution settings
• Keyboard, scroll, and controller battery input forwarding
• mDNS host discovery + subnet scan
• Multi-host pairing (up to 8 hosts, MRU ordered)
• Game grid UI with icon caching
• Button mapping UI
• Settings menu with preset bitrates
• On-screen keyboard for IP entry

Phase 4: Release 🔧 In Progress

• Beta release for real hardware testers (v0.2.0-beta)
• Hardware test results published (PSP-1000, 802.11b)
• AMD encoder A/B test (14 combos — best: lowlatency_high_quality + speed + vbr_latency)
• Encoder settings guides (AMD, NVIDIA, Intel, Software)
• PSP-2000/3000 testing (64 MB RAM, 802.11b)
• PSP Go testing (802.11b, Bluetooth)
• Performance benchmarks across CFW versions
• Community testing feedback integration

Phase 5: Polish (Planned)

• Wake-on-LAN support
• Touchscreen overlay (PSP Go)
• Resume/reconnect without full RTSP renegotiation
• Configuration backup/restore
• Localization (Japanese, European languages)
