# Compila o Pocket Aquarium (homebrew de Game Boy de Chris e Tyler Jackson / Creative Name Studios, GB Compo
# 2025, GPL-3.0) a partir do projeto GB Studio do commit a95f9fd (gbcompo25/pocket-aquarium-gbcompo25), com o
# GB Studio 4.1.3 (MIT) em linha de comando (make:rom), sem o Electron (um stub no lugar do pacote, que o CLI
# so importa), e o GBDK-2020 que o proprio repositorio do GB Studio traz em buildTools/darwin-arm64.
# Mudancas nossas (publicadas junto do fonte):
#   pocket-aquarium/strip-sound-effects.py        tira os efeitos sonoros (o repositorio diz que NAO estao
#                                                 sob a GPL; ver LICENSE.txt do jogo); a musica fica;
#   pocket-aquarium/fixed-save-signature.patch    no GB Studio: a "assinatura do save" vira um valor fixo (era um
#                                                 hash do projeto inteiro que muda a cada execucao), para a build
#                                                 sair igual toda vez.
# Precisa de node (artifacts/tools/node-v24.21.0), git e acesso ao registro npm (yarn 1.22.22 + yarn.lock do GB Studio).
