R> Divino, por acaso esse "River" pra ZX81 ainda existem em fita, ou o
R> código impresso, sei lá ?

É provável que exista, talvez o Fred tenha sido mais cuidadoso que
eu pois muitas das minhas fitas de ZX 81 estragaram por mofo. Da
última vez em que estive com elas separei as mofadas das
aparentemente boas (no visual) e embalei o que sobrou em plástico.

Isso foi em 1999 ... o treco todo está em algum lugar da casa onde
mora minha filha em Ribeirão Preto.

O jogo foi criado usando vários caracteres para representar o avião
e personagens.. usamos aqueles conjuntos de caracteres especiais do
Sinclair e o jogo rodava igual tanto com caracteres redefinidos
quanto os normais.
    
As paisagens foram montadas usando um mesmo simbolo e gravadas em
blocos do tamanho da tela do Atari. Algumas letras agrupadas formam
padrões legais e permitem muitas combinações, vejam uns exemplos no
final do texto, mas é preciso ver numa fonte sem serifa pra ficar
bom:

O programa (todo em assembler) simplesmente trazia os blocos de
tela e fazia um scroll, enquanto o desenho do avião era plotado por
cima e era feito o reconhecimento do caracter espaço (que
representava o rio) se fosse outro o programa desviava para uma
rotina de colisão com alguma coisa.

Foi legal fazer este jogo porque trabalhamos a 4 mãos, cada um fez
uma parte do código e depois compilamos tudo junto e deu
certíssimo. Gosto e lembro bem deste trabalho porque é o único que
consegui fazer em parceria com alguém, todos os meus outros foram
trabalhos solo.

R> PS.: achei a fita do Pinball de sua autoria :-) vou fazer aquele
R> esquema do cabo paralelo pra tentar carregar o jogo com o emulador
R> e disponibilizar a ROM.

Beleuza ... se conseguir manda o making off depois pra gente ver
...

Um grande abraço,

Exemplo de paisagem de fundo para o River Raid no TK, usando a letra
L, as paisagens se emendavam na parte superior e inferior da tela e
geravam um scroll infinito e aleatório, diferente do River original
em que o desenho era sempre o mesmo.

Nos exemplos abaixo, redefinindo a letra L se podia criar padrões de
alta qualidade, mesmo na resolução limitada do Zx81.

Se juntar os desenhos fica um loop infinito, vá para o final da página
e aperte a tecla de seta para cima para ver um exemplo bem tosco :8))
