Game data

Pokémon Showdown

• What: Generation-1 battle data — base stats and moves — extracted into showdown_gen1_basestats.h and showdown_gen1_moves.h. These headers are generated from the Showdown data set and are gitignored, not committed.
• Project: https://github.com/smogon/pokemon-showdown
• License: MIT
• The generated headers carry an SPDX-MIT block and Showdown attribution — do not strip it.

PokéAPI

• Project: https://pokeapi.co

UI & graphics

LVGL

• What: The embedded UI toolkit underlying the device UI and the MonsterMesh terminal (pulled in via Meshtastic device-ui).
• Project: https://lvgl.io · https://github.com/lvgl/lvgl
• License: MIT

LovyanGFX

• What: The T-Deck TFT display driver.
• Project: https://github.com/lovyan03/LovyanGFX
• License: FreeBSD (BSD-2-Clause-style)

meshtastic-device-ui

• License: GPL-3.0

Cozette font

• License: MIT

Transitive dependencies

Because this is a Meshtastic fork, the build also pulls in Meshtastic’s own dependency stack — including RadioLib (LoRa radio driver), Nanopb (protobuf), and various Adafruit sensor/display libraries. Each is governed by its own license; see the respective libraries.
