# D750 QEMU Verification Prototype: early Nikon D750 firmware execution in QEMU

> D750 QEMU Verification Prototype investigates early execution of Nikon D750 firmware with a QEMU board overlay and host-side scanning and logging tools. The author reports that a selected entry function ran and returned, while the observed fragment produced no MMIO accesses or UART output. A separate toolchain changes selected 1080p bitrate-table entries in a user-supplied firmware image.

## Requirements & limits

- **Prerequisites:** Provide local D750_0115 firmware modules.
- **Prerequisites:** Build the overlay into QEMU with a C toolchain; QEMU 11.1.0 is the documented compiled version.
- **Limits:** The camera UI, sensor and storage are outside the prototype; the bitrate change has no camera shooting test.
- **License:** GPL-2.0.
