# Compila Qulqy (homebrew de Game Boy Color de Mateusz Teklak "plyr0", BSD-3-Clause) do commit 6d1e676
# do Codeberg com o GBDK-2020 4.4.0, sem a tela do logo da GB Compo 2025 (marca de terceiros). Sem o
# patch, esta build sai identica byte a byte ao qulqy_jam.gbc do itch.io (sha256 bd133d95...).
#
# O patch Builds/qulqy/no-compo-logo.patch tira a tela do logo (e a espera pelo Start que vinha com
# ela) e ressemeia o gerador aleatorio no primeiro lance depois de carregar um jogo salvo (sem a
# espera, a semente do clock() seria sempre a mesma); o script apaga os arquivos do logo.
#
#   src/FredGames.Bundler/Builds/build-qulqy.sh

# Saida: artifacts/build/qulqy/qulqy.gbc
