SpeccyP is open-source firmware for emulating ZX Spectrum-compatible machines on Raspberry Pi RP2040, RP2350A, and RP2350B microcontrollers. It is aimed at makers building compatible Raspberry Pi Pico-based hardware projects, rather than users looking for a conventional desktop or mobile emulator. The supported range includes the ZX Spectrum 48 and multiple Pentagon, Scorpion, Navigator, and MurmoZavr configurations, with precompiled firmware available for several supported boards.

Platform fit is SpeccyP’s defining strength. Video can be delivered through HDMI, VGA, or TFT, while audio supports soft and I2S AY-3-8910 modes and TurboSound. Input options cover USB and PS/2 keyboards, USB mice, NES and Xbox gamepads, and wireless gamepads. That combination gives hardware builders room to match the emulator to a specific display, sound path, and control layout, but it also makes the project less suitable for anyone who wants to install an emulator on a general-purpose computer.

For software and media handling, SpeccyP supports TRD and SCL disk-image mounting, TAP tape-file loading, SD-card file loading, and quick save and load states. Its open-source model is free and avoids a conventional plan structure. Choose SpeccyP when the goal is a dedicated ZX Spectrum-style build around supported Raspberry Pi microcontrollers, especially where varied video, audio, storage, and controller connections matter. Choose another option if the priority is desktop or mobile deployment, broad host-platform coverage, or an emulator that does not require compatible microcontroller hardware.

SpeccyP pros and cons

  • Where it wins
    • Supports Spectrum, Pentagon, Scorpion, Navigator, and MurmoZavr models
    • Offers HDMI, VGA, TFT, AY-compatible, and I2S output options
    • Handles disk images, TAP files, save states, and multiple controllers
  • Where it doesn't
    • Requires compatible RP2040, RP2350A, or RP2350B hardware
    • Targets microcontroller projects rather than desktop or mobile computers
    • Hardware setup and peripheral compatibility depend on the chosen board
