Open-source Nokia DCT3 emulator boots real firmware in browser and native SDL
An open-source emulator and analysis toolkit for Nokia DCT3 phones models the MAD2 platform and boots real firmware in a browser or native SDL GUI.
For engineers working with legacy mobile hardware, this provides silicon-level emulation of the DCT3 platform without patching firmware, enabling analysis of GSM, SMS, and WAP behavior. It also serves as a software preservation tool for obsolete devices, though users must supply their own firmware images.

The emulator models the MAD2 ASIC, CCONT power controller, TMS320C54x DSP, LCD, keypad, SIM, and EEPROM at silicon level.
It supports GSM registration, voice calls, SMS, WAP over circuit-switched data, and an MBUS service bus for period Nokia service tools.
Users must provide their own legitimately-obtained .fls firmware images, as the repository contains no copyrighted firmware or flash dumps.
