| Issue | Cause | Solution |
|-------|-------|----------|
| Invisible walls / missing ground textures | Depth buffer emulation error | Set Rendering Mode to Non-Buffered Rendering (toggles off some effects but fixes geometry) |
| Black screen after cutscene | Video codec bug | Enable Decode Video with Software (Settings → System → Software Video Decode) |
| Extreme slowdown in open world | CPU thread sync | Lower Emulated CPU Clock to 222 MHz (under System → Emulation) – this matches original PSP speed and prevents over-sync |
| Pedestrians flickering | Z-fighting | Set Depth Range Hack: On (in Graphics → Hack settings) |
| No audio during gunfights | Atrac3+ decoding | Install atrac3plus.prx (place in PPSSPP/assets/ folder) and enable Atrac3+ decode via SonicStage |
| Save state crash | Memory overlap | Use in-game saves only for long sessions. Save states okay for short play. |
| Aspect | Performance on PPSSPP | |--------|------------------------| | Boots into main menu | ✅ Yes | | Cutscenes (pre-rendered) | ✅ Smooth | | In-game graphics | ✅ Good (with tweaks) | | Audio/music | ⚠️ Occasional stutter | | Frame rate | ✅ 30 FPS target (drops in heavy traffic) | | Save/load | ✅ Works fine | | Major crashes | ❌ Rare (only with wrong settings) | true crime new york city ppsspp work
Even with emulation, you cannot fix the game's core coding errors. | Issue | Cause | Solution | |-------|-------|----------|
