nRF52840 Doom

Doom port to an nRF52840-based USB BLE dongle, the Adafruit CLUE board, and any device using Nordic Semiconductors nRF52840. Coded by Nicola Wrachien.

Features

  • Based on the excellent doomhack's GBA Doom Port (https://github.com/doomhack/GBADoom) with some Kippykip's additions.

  • Wireless gamepad with audio streaming like Wii remote.

  • Extremely fast. Run almost always above 30 fps (except Episode 4 of Ultimate Doom).

  • Additional gamepad support for Adafruit CLUE option (or other devices with enough I/Os)

    • Parallel Keyboard (each key routed to one GPIO).
    • MCP23008 I2C Port Expander.

  • Tested with:

    • Shareware DOOM1.WAD.
    • Full Commercial DOOM.WAD
    • Ultimate Doom WAD.
    • Doom 2 WAD.

  • Full Vanilla Render engine, including Z-depth lighting.

  • Player's weapon also is subjected to ambient light.

  • Monster behavior and sound propagation implemented.

  • Sound FX support.

  • Cheats implemented.

  • NEW: 2022-04-24: Doom1.WAD v1.9 built-in demo support!

What's missing?

  • Music.

  • Demo playback: for now only Doom1.WAD v1.9 built-in demos are supported.

  • Need to be debugged.

  • Multiplayer not implemented.
