# Headless Ninja Volley (Master System, Haroldo O. Pinheiro, v0.9, Unlicense): tira a ROM do pacote que o autor publicou no
# SMS Power e completa o arquivo com bytes 0xFF ate 16 KiB. A ROM do autor tem 12.453 bytes (o z88dk grava so o que o jogo usa),
# e o Gearsystem recusa arquivo que nao seja multiplo de 1 KiB; num cartucho de verdade o resto do chip tambem fica em 0xFF.
# Nenhum byte do jogo muda.
