# Compila o Go-inovation (plataforma de exploracao "Ino-vation 2007" de Omega, portada para Go + Ebitengine por Hajime Hoshi; MIT)
# para WebAssembly a partir do commit d53d47a de github.com/hajimehoshi/go-inovation, com o Go 1.27.2 (Builds/go-ebiten/common.sh).
#
#   src/FredGames.Bundler/Builds/build-go-inovation.sh
#
# Mudancas no jogo (go-inovation/go-inovation-fredygames.patch, publicado junto do fonte): so os textos de 7 itens, em ingles e japones,
# que nomeavam marcas e jogos comerciais (um tenis, um robo de anime, um jogo de tiro de 1995, personagens de filme e serie) e agora trazem
# nomes genericos. O jogo nao usa rede, links nem armazenamento, e o build web nao liga o Steamworks (so entra com a tag `steam`). As
# imagens e sons vem embutidos no binario (ino/internal/assets). O idioma segue o do navegador (ingles ou japones).
# Alem do patch, go-inovation/neutral-poed.py apaga o texto "POed" (nome de um jogo comercial) do sprite do item "Po'ed" nas folhas de
# imagens (color e mono) e poe um icone neutro no lugar.
#
# Saida: artifacts/build/go-inovation-d53d47a/{go-inovation.wasm,wasm_exec.js,go-inovation-licenses.txt}; dois builds seguidos dao os
# mesmos bytes.
