+Boots without patches and reaches the title screen with correct rendering.
+- ~60 s after launch a full 3D race-track scene renders with the tip "You can take a look at all the items you earn within the Collection menu!" (looks like a loading-tip scene).
+- ~120 s: the "PAW Patrol Grand Prix" key art screen renders correctly at 60 fps.
+- Two AvPlayer intro videos start/stop; stderr shows `st: 0 edit list: 1 Missing key frame while searching for timestamp: 0` and `Cannot find an index entry before timestamp: 0.` (cosmetic so far).
+- Log warning: "game uses occlusion queries, which are currently treated as always visible; GPU usage may be higher and FPS may be lower."
+- With an empty pipeline cache the first minute is slow: the frame counter stalls for a while and drops to single-digit fps during bursts of new shaders (ends at 35 VS / 54 PS / 27 CS / 4 GS compiled by 120 s).
+- Working set grows to ~3.6 GB by 90 s and stays flat.
+
+Screenshots of the race-track and title-art scenes exist locally; happy to attach them in a comment if useful (not postable through this tool).
+
+## Steps to reproduce
+
+1. Start KytyPS5 with an empty `_PipelineCache`.
+2. `kyty_emulator.exe --game "...\PPSA05521-app0"`.
+3. Wait ~2 minutes without giving input.
+
+## Expected behavior
+
+Intro videos, then the main menu. No known issue beyond the cold-start compile stalls.
+
+## Extra notes
+
+Built with clang-cl from source (upstream `main`).
+
+*AI disclosure: I used Claude Code to help run the game and collect the log; I reviewed the results myself.*
