SnapRoll Firmware Builder

Experimental browser builder using the stable V057 firmware automatically. Users only upload the frame and optional sound/menu assets; firmware generation happens in the browser.

1. Firmware template

V057 — JH_5813_0597B697_V057.bin
Checking firmware…

The page automatically loads the stable V057 firmware from this site. Visitors do not need to upload a BIN.

2. Frame

760×760 or 720×720. A 760×760 file is cropped by 20 px on each side; artwork is not resized.

Stable 6-colour mode
Six colours, no dithering.

3. Optional WAV replacements

Blank = preserve V057 sound exactly. Uploaded WAVs are automatically converted to the camera resource's original sample rate, channels and bit depth while preserving the uploaded sound's duration.

4. Optional menu images

Blank = keep V057 image. PNG/JPG replacements are converted to 128×128 JPEG. The builder can compact these menu graphics if the frame needs more space.

Auto-compact menu JPEGs if needed
Reclaims firmware sectors from the six small menu images.
Advanced: losslessly compact DT background
Can reclaim one additional sector. Use only if the normal build is one sector short.

5. Preview & build

Captured-photo frame
Camera LCD preview
Upload a frame PNG, then click Prepare & analyse. The stable V057 firmware loads automatically.

Experimental. A structurally valid BIN can still fail on hardware. Keep the official/stable V057 firmware available as a recovery copy and do not power off the camera during an upgrade.
