What the hardware does

Version-specific camera scripts replace the stock shutdown image on a Ricoh GR IV with a personalized picture.

How the agent helped

The creator credits Codex with firmware analysis, scripting, testing and documentation, and shows the modified shutdown image on the camera. This is separate from the StickS3 viewfinder project.

Before you build

Model/firmware-specific modification requires verified backups and recovery planning. Distinct from the StickS3 remote-viewfinder project.
