# Sisu DCP-3: reconstructing Nokia 3210 firmware behavior

> Sisu DCP-3 recreates the Nokia 3210 NSE-8 v6.00 experience as new C firmware for a replacement Rev B2 mainboard. It uses original-firmware analysis to guide behavior and presentation, while documented ROM research reconstructs the battery gauge; fonts, tones and other Nokia-derived assets are generated locally from the user's firmware copy.

## Requirements & limits

- **Prerequisites:** A Rev B2 board with RP2354B, Telit LE910C1-WWX and the named Nokia 3210 parts is the hardware target.
- **Prerequisites:** The build uses CMake and the pinned Raspberry Pi Pico SDK 2.3.1 commit; a user-supplied original v6.00 firmware copy is needed to generate assets.
- **License:** Project-authored code and documentation use the Unlicense; separately licensed third-party files retain their terms.
