Builds the pcppcp community firmware locally in this browser. Your original firmware is checked, patched and repacked without being uploaded.

Checks the selected author on open, on return to the tab, and every five minutes while visible. Metadata may be cached for up to one minute. A new release never replaces an active build. New incompatible formats require a LAB update.

INPUT
Original R246 .op1 firmware
OUTPUT
Patched .op1 firmware
TIP
Keep the untouched original file as your recovery copy. Checks verify file contents, not physical-device behavior.
