# Compila StickFighter (homebrew de Arduboy de Tony Mamacos, MIT) do commit deb2492 de
# github.com/tonym128/stickfighter, com versoes fixas: o nucleo Arduino AVR 1.8.6 (LGPL-2.1; avr-gcc 7.3.0) e a
# biblioteca Arduboy2 6.0.0 (BSD-3), pelo arduino-cli 1.5.1. O autor nao publicou .hex no repositorio (so o Makefile,
# que pede o pacote arduboy:avr); servimos este build, com a placa arduino:avr:leonardo, cujo fonte completo
# hospedamos junto: o jogo no commit (sem os dois executaveis de Linux e o GEMINI.md do repositorio), o Arduboy2,
# o nucleo AVR e este script. O codigo do jogo entra sem alteracoes. Dois builds seguidos dao o mesmo sha256.
