# Compila i-20000 para Arduboy (i4arduboy, da Planet Marimo, MIT) do commit 60e156f de
# github.com/d371ed/i4arduboy, com versoes fixas: o nucleo Arduino AVR 1.8.6 (LGPL-2.1; avr-gcc 7.3.0) e a biblioteca
# Arduboy 1.1.1 (BSD-3; a parte de som, ArduboyTunes, e GPL-3), pelo arduino-cli 1.5.1. O codigo do jogo
# entra sem alteracoes. O autor nao publicou .hex no repositorio; servimos este build, cujo fonte completo
# hospedamos junto: o jogo no commit, a biblioteca, o nucleo AVR e este script. Dois builds seguidos dao o
# mesmo sha256.
