Digitakt & Digitone splash mods

Boot-splash mods for the Elektron Digitakt mk1 (OS 1.53) and Digitone mk1 / Digitone Keys (OS 1.43), built for elekloader. They change only the main OS section, need the matching core mod, and can be combined with other non-conflicting mods. No Elektron firmware is included.

Digitakt mk1 (OS 1.53)

mod	what it does	sources
rare-splash	boots on the alternate stock animation, the one the unseeded selector never reaches	1 instruction
digitussy	animated: the DIGITUSSY wordmark bobbing over rising particles	C + asm
digitrash	animated: the DIGITRASH wordmark and a trash can with six flying flies	C + asm
aba-bootanim	example animated GIF splash, generated by make-bootanim from aba.gif	asm

(left: the usual boot animation, ~367 lit pixels — right: the rare one, ~666; both captured from a real 1.53 image in digiemu.)

Digitone mk1 / Digitone Keys (OS 1.43)

The same mods, ported, plus the generated example (see digitone1/ for the addresses). The panel is the same screen, so the graphics and image format are identical.

mod
digitone1/mods/rare-splash	the alternate stock animation
digitone1/mods/digitussy	animated wordmark + particles
digitone1/mods/digitrash	animated wordmark + flies
digitone1/mods/aba-bootanim	example animated GIF from make-bootanim

Conflicts

digitussy, digitrash and aba-bootanim draw over the intro; rare-splash changes which stock animation runs. The three draw mods hook the same present sites, so install one of them; rare-splash patches a different instruction and combines with any of them. The same rule holds within each device section (a Digitakt mod and a Digitone mod are never combined — they target different OS files).

Releases

The DigiSplash 1.1 release is twelve splashes, in releases/ (dt/ for the Digitakt, dn/ for the Digitone) and as elemods-only zips. Install one draw mod at a time — see releases/README.md.

Quick start

cd elekloader

# Digitakt mk1: build a mod, then a flashable firmware with core
python -m elekloader.sdk.build ../digitakt-splash-mods/mods/digitussy --stock Digitakt_OS1.53.syx
python -m elekloader.patch --stock Digitakt_OS1.53.syx \
    --mod mods/core/out/core-2.1.elemod \
    --mod ../digitakt-splash-mods/mods/digitussy/out/digitussy-1.0.elemod \
    --out digitussy.syx --version 2.0s

# Digitone mk1 / Keys: the same, with the Digitone stock and core-dn1
python -m elekloader.sdk.build ../digitakt-splash-mods/digitone1/mods/digitussy \
    --stock Digitone_and_Digitone_Keys_OS1.43.syx
python -m elekloader.patch --stock Digitone_and_Digitone_Keys_OS1.43.syx \
    --mod mods/core-dn1/out/core-dn1-2.0a.elemod \
    --mod ../digitakt-splash-mods/digitone1/mods/digitussy/out/digitussy-1.0.elemod \
    --out digitussy-dn1.syx --version 2.0s

digitussy, digitrash and the generated bootanims need the m68k toolchain (C and assembly); rare-splash has no sources and builds without it.

Make your own from a PNG or GIF

tools/make-bootanim/ turns an image or an animated GIF into a ready-to-build splash mod (a multi-frame animation, or a single frame):

tools\make-bootanim\make-bootanim.bat hamster.gif
tools\make-bootanim\make-bootanim.bat logo.png --name "My logo" --dn

It writes the mod folder (frames, splash.s, mod.json); build and install it with elekloader as above. See tools/make-bootanim/README.md. The committed aba-bootanim mod (and its Digitone twin) was made this way from tools/make-bootanim/aba.gif.
