DigiAlchemy GamePack v0.21 — a pocket arcade for the Elektron Digitone mk1 / Digitone Keys (OS 1.43).

Press MIDI+YES for a game-select menu, then play:

  • DOOM — a from-scratch DOOM-style raycaster (ordered-dither walls, billboard sprites, HUD, weapon, doors, chasing monsters; title DOOM — KARL MARX EDITION).
  • INVADERS — a very lightweight Space Invaders (6×4 fleet, ship, bullets, lives, score).
  • SNAKE — a grid snake that grows and speeds up with every dot.

Assets

  • DigiAlchemy-GamePack-0.21.zip — the release package: the .elemod plus README.md (install), NOTICE and LICENSE.
  • digidoom-0.21.elemod — the mod on its own.

Build the firmware

The .elemod is a linkable elekloader mod (not a firmware image). Build the flashable .syx locally from your own stock OS plus the core:

python -m elekloader.patch --stock Digitone_and_Digitone_Keys_OS1.43.syx `
    --mod core-dn1-2.0a.elemod --mod digidoom-0.21.elemod `
    --out custom.syx --version 0.21

Requires core-dn1-2.0a.elemod (elekloader mods/core-dn1) and your stock Digitone_and_Digitone_Keys_OS1.43.syx.

Controls

  • MIDI+YES — open / close the menu
  • Menu: UP/DOWN select · YES start · NO exit
  • DOOM: arrows move/turn · YES fire · NO use a door
  • INVADERS: LEFT/RIGHT move · YES fire
  • SNAKE: arrows steer

Notes

  • No firmware is distributed. Build the .syx from your own stock OS.
  • Recovery: hold FUNC on power-up → startup menu → TRIG 4 (OS UPGRADE) → send the stock .syx.
  • Licence: GPL-2.0-or-later.
