Caduceus for OM-3 v0.26.2

Caduceus for OM-3 v0.26.2

Films load at power-on, the dials step through the films, and three fixes.

• No half-press any more: your films and changes load from the card by themselves a moment after the camera
  starts, and live view and the labels follow. (A half-press or OK still loads them too.) This comes from
  fernandezk26's fork: thank you.
• Super control panel: with the Picture Mode cell selected, the dials go COLOR 1–4, then FILM 1–20, and the label
  follows.
• Fix: Film Grain with RAW+JPEG. In v0.25 to v0.26.1 a photo with Film Grain and image quality RAW+JPEG was
  saved, then the screen went black and the camera froze. Fixed: grain works the same with RAW+JPEG and JPEG only.
• Fix: "FILM N" on the shooting screen and in the viewfinder was replaced by "COLOR n" when COLOR n's own
  settings had been changed.
• Fix: bad bytes in EDITS.BIN that could make a film's saved changes unreadable (found by fernandezk26).
• Everything from v0.26.1 stays.
• Firmware camera-tested (2026-11-09, build sd4).

Copy to the card: DCOLYMP (flash it: hold OK, then switch the camera on) and the OM3MOD file GUIDES.BIN
(made for this firmware: always copy it with it). LABELS.BIN, TONES.BIN and the optional LOOKS.BIN (the tuned 20
film sims; it replaces your own films) are the same as v0.26.1. Keep your EDITS.BIN, NAMES.BIN and BUNDLES.BIN.

Going back to v0.26.1 or older: flash that version with its own GUIDES.BIN; your files still work. Half-press
once after switching on again.

Make it: run the launcher and press Return (or python3 firmware/patch.py --release v0.26.2). The files here are the
patch (only the bytes Caduceus for OM-3 adds; no OM firmware), the card files and the expected checksums. Full list of
changes: CHANGELOG.
