Código da máquina x86, 1729 1619 1468 1382 bytes
Como funciona: os blocos são gerados por uma combinação de compactação RLE, imagens de 2 bits e código processual. Depois que os blocos são gerados na memória, o programa cria uma matriz de índices de bloco. Isso é carregado primeiro com o plano de fundo repetido. Depois disso, os tubos, blocos flutuantes, pirâmides e o mastro da bandeira são desenhados proceduralmente. Os canos, colinas, arbustos e pirâmides podem se estender abaixo do solo, mas ficam encobertos quando os ladrilhos da rocha são escritos a seguir. Finalmente, os valores do bloco do castelo são simplesmente copiados para o local correto. Para gerar o arquivo de imagem, o cabeçalho e a paleta BMP são armazenados no arquivo como dados e são gravados primeiro. O programa é executado através da matriz, gravando a linha apropriada do bloco correspondente para cada posição.
Uso: Execute mario.com, ele gerará "m.bmp", um arquivo de imagem BMP padrão. O arquivo é criado como um arquivo oculto, pois acabou sendo menos bytes.
Faça o download de um arquivo ZIP contendo o código fonte e o binário, além da saída.
Código de montagem para gerar o arquivo executável:

tudo isso com os ladrilhos em uma linha, pois isso reduzia bastante o código pouco. Tentei coisas semelhantes com configurações diferentes (2 * 16, 4 * 8), mas nenhuma com um resultado médio melhor.
