A guitar amp modeller running on an ESP32-S3 microcontroller executes full NAM A2 profiles at 48 kHz with integrated DSP effects, cabinet simulation, and tuner. The firmware compiles to C++ with a touch UI and loads custom amp profiles from SD cards; it also runs on multiple platforms via Gea Stack including macOS, Windows, Linux, iOS, Android, and web browsers.
A 386 PC emulator firmware for the RP2350 microcontroller enables full i386 CPU emulation with DOS, Windows, and Linux support via VGA/HDMI output, SD card storage, and multiple input methods. The project supports various RP2350-based boards and provides runtime configuration for memory, CPU generation, sound devices, and disk image management.
