Caduceus v0.15 (early development)

Caduceus v0.15: first public release (early development)

⚠️ Unofficial, experimental firmware modification. Bugs will appear and flashing can brick your camera or lose data. The author accepts no responsibility for any damage. Provided "as is", without warranty (Apache License 2.0 §7–8). Remove the EP7MOD folder for near-stock behaviour; the restore file returns the camera fully to stock 1.1.

What's in it

• Film simulations in the camera: 29 colour looks (Provia, Velvia, Classic Neg, Kodachrome 25/64, Portra 160/400, Ektar, Gold, CineStill 50D/800T, Vision3 250D/500T, Superia, Aerochrome-style IR, Cross Proc…), picked per Colour Profile slot on a new Film page in the stock colour wheel. Names show in Picture Mode.
• Look editor: INFO cycles Saturation → Hue → Light → Film → Extras; the wheel follows the page; edits save back to the SD card.
• Extras per profile: grain, bloom ↔ clarity, WB shift, Art Effects (Star Light, Pin Hole, Blur).
• Mono film presets: Pan F, Acros, T-Max, SFX, Tri-X, HP5, Delta 3200, Sepia, Selenium, Cyanotype (INFO in the mono editor).
• True log video: a log curve already hidden in the firmware, unlocked with movie picture mode = Muted.
• XPan 65:24 and 21:9 stills: with matching live view, playback and XPAN/UW size labels.
• Longer recording limit.

Install (no firmware files are distributed)

OM's licence forbids redistributing their firmware, so you build the update on your own computer:

1. Download this release's source zip (below) and unzip it.
2. python3 caduceus.py build --release v0.15 (Windows: py caduceus.py build --release v0.15). It downloads OM's official 1.1 file and checks every hash.
3. Copy DCOLYMP and EP7MOD from out/ to the SD card. Hold OK and switch on to flash.

Full guide: docs/INSTALL.md. Only the E-P7 on firmware 1.1 is supported.
