# Compila Cat Fish (homebrew de Game Boy Advance de Auberon Lopez e Matt Phan, GBA Jam 2026, MIT; audio CC0)
# do commit 3b99b74 do repositorio alope107/pounce, com o Butano 21.8.0 (zlib), a engine que o jogo usa. O
# repositorio nao traz ROM. Toolchain: ver gba-butano-toolchain.sh (GCC arm-none-eabi 14.3.rel1 com as regras
# e o crt0 do devkitARM, no lugar do pacote do devkitPro, que nao baixa neste ambiente).
# Mudancas nossas: graphics/fritobag.* fica de fora (e uma sacola de salgadinho com a marca Fritos, e o codigo
# nunca a usa) e o titulo do cabecalho da ROM vira CATFISH (o Makefile deixou "SCENE").
#
#   src/FredGames.Bundler/Builds/build-cat-fish.sh
