Seal Eggs firmware flasher
Add community mods to your own copy of the official Sealegs 1.3.5.0 firmware.
🔒 Runs entirely in your browser. Your firmware is never uploaded, and this site hosts none.
1Load your official firmware
Use the unmodified Sealegs.1.3.5.0.bin from the manufacturer. Other versions are refused, because every patch targets exact addresses.
2Choose your mods
Mods can be mixed freely, with one rule: Live reverse needs Digi doppler, so picking reverse turns doppler on. Reverse, character and doppler share one engine, which is added once.
3See what changes
The whole flash image, one square per 256 bytes. Grey is code and data already in the firmware, pale is empty space, and colours show what your selection writes. Hover or tap a square for details.
