Heavy games at stock clocks.
- PlayStation: games others need a 2.0 GHz overclock for now run full speed on stock clocks: NEON FMV decoding, and the async GPU thread (which serializes on this chip) off by default. Tony Hawk 2's required clock dropped 1584 to 1008 MHz.
- Optimize CPU: per-chip voltage calibration runs reliably end to end, and recovers itself if a test freezes the device.
- Reliability: atomic saves, half-install-proof updates, and a clean exit on a bad core.
Re-run Optimize CPU once (v1.1/v1.2 calibrations don't carry over; from v1.3 on they survive updates). Copy MinUI.zip to the card root to update.
