# Compila o crisp-game-lib para Vircon32 (joyrider3774; MIT, a partir do crisp-game-lib de ABA Games; 266 minijogos em um
# cartucho) do repositorio do autor (github.com/joyrider3774/crisp-game-lib-portable_vircon32, commit 9c18ea5) com a toolchain
# oficial pinada (Builds/vircon32/). Sem mudancas no fonte; o passo opcional v32opt do Make.sh fica desligado (SKIP_V32OPT=1).
# Dois builds seguidos; os dois .v32 precisam ter o mesmo SHA-256.
