FREEDOOM2.WAD.
A startup game picker with one-minute display sleep and button wake.
Four-button controls for movement, firing, use, weapon switching, menus,
backward movement, and jumping.

Serial, plus a reproducible command-line flasher.
Audited GPLv3 firmware source with pinned SDK, engine, and flasher

This release targets the original HuskyLens K210 model, SKU SEN0305. It is
not intended for HuskyLens 2.
The port is intentionally soundless.
Flashing replaces the firmware currently installed on the device.
Commercial DOOM data is not included. Supply a legally obtained DOOM.WAD
or use the free Freedoom IWADs on a FAT32 microSD card.
