- Includes an emulator probe that reports hot PCs, recent P9/SCI accesses, serial report queue/gate traces, RAM lifecycle watches, final SCI1/TXI state, and captured P9 byte candidates while running the real ROM.
- Includes an RX command probe that boots until SCI1 RXI is serviceable, injects host six-byte frames through RDR/RDRF, can optionally schedule 38400 8N1 byte arrivals at real UART spacing, listens for device TX frames, and reports serial latch/table/LCD-buffer and emulated-LCD effects.
- Includes a bench helper for replaying the emulator-derived CONNECT LCD frame sequence against the real device through COM5, with optional COM6 relay power cycling and timestamped capture logs.
- Includes a bench ACK probe that reproduces the `01 00 00...` -> `01 00 01...` visible retry burst, waits for `07 80 40 20 90 2D`, then sends a candidate command-5 ACK and reports whether the target keeps repeating.
- Includes a bench-log replay harness that feeds recorded host TX frames back into the ROM emulator with bench-style UART byte timing by default and asserts parity against the real device's observed response/LCD state.
