Development fork of Prosper — PS5 Emulator Runtime
ProsperT24 is our development fork based on the original Prosper project by mattias800. This fork focuses on CLI execution, diagnostics, runtime observation, and compatibility experimentation for PS5 game emulation. We document our validation work, frame capture achievements, and rendering pipeline experiments here.
| Game | PPSA02929 / Dreaming Sarah |
| Engine | Unity / IL2CPP |
| Evidence ID | EXP-CLI-FRAME-REAL-001 |
| Status | ✅ REAL FRAME CAPTURED |
PPSA02929 (Dreaming Sarah) was successfully booted through our CLI (boot_trace) and produced a real rendered first frame captured via --capture-first-frame.
The initial first-frame capture has now been extended with a real frame sequence showing the boot/splash state followed by later rendered game-loading content. The CLI demonstrates continued observation of real rendered output beyond a single isolated frame.
This is not a synthetic test pattern — it is actual rendered game output from the PS5 present path.
Visual content: Splash screen showing pixel-art teal dog character + "AIKA GAMES" logo + "RATTAL" branding text — consistent with Dreaming Sarah's actual boot screen.
The CLI has now been validated beyond a single first-frame capture. For PPSA02929 / Dreaming Sarah:
- Frames 1–220 show the initial boot/splash state (RATALAIKA GAMES logo)
- Frames 260–600 show later loading/game-rendered content (title screen, loading progression)
These are captured runtime frames, not synthetic test patterns.
Representative captured frames:
Frame 200: Boot/splash screen with RATALAIKA GAMES logo
Frame 260: "Dreaming Sarah" title appearing
Frame 420: Title screen with loading indicator
This demonstrates that the CLI can observe a continuing sequence of real rendered output from boot through game initialization.
Our fork extends Prosper's boot_trace tool with frame capture diagnostics:
- Game boot via
boot_trace(CLI/headless-style execution) - Runtime/boot diagnostics output
- VideoOut/present observation (3840×2160 buffers)
- First-frame capture (
--capture-first-frame) - Continued frame sequence observation
- Real rendered-frame validation
- Frame metadata/integrity reporting
- Observer-only capture — does not modify game runtime behavior
