Flash
A browser firmware workbench: read and write flash chips through a hardware programmer, then inspect the dump in a hex editor with forensics and checksum tools.
Read, inspect and preserve firmware from the browser. Connect a serprog-compatible SPI programmer directly over Web Serial, or pair a small local bridge that drives flashrom for a CH341A or MiniPro for a TL866II+/T48 — or use the simulator to practise with no hardware at all. A chip library covers capacity, voltage, interface and pin-1 orientation before anything is seated, and writes are gated behind an explicit backup-and-wiring confirmation and a full byte-for-byte read-back. Imported or read images are analysed locally in a hex editor with forensics and checksum tools that can find header/trailer checksum candidates and rebuild them in the buffer, while a signed-in workspace keeps immutable copies in a firmware archive with an activity log. A release candidate: hardware support is marked experimental.
