Preciso de ajuda para converter dados

[leandro Riato]

Tenho um arquivo binário que possui dados do tipo:

74 74 74 74 74 74 74 74 74 74 80 8B 8B 8B 8B 8B 8A 8A 8A 8A 8A 8B 8B 8B 8B 74 74 74 74 74 74 74 74 74 74 74 74 74 74 74 80 80 8A 8A 8A 8B 8A 8A 8B 8B 8A 8B 8B 8B 8B 74 74 74 74 74 74 74 74 74 74 74 74 74 74 74 80 80 8A 8A 8B 8B 8B 8B 8B 8A 8B 8A 8A 8A 8B 7C 74 74 74 74 74 74 74 75 74 74 74 74 74 74 74 80 8B 8B 8B 8B 8B 8A 8A 8B 8B 8B 8B 8B 8B 8B 74 74 74 74 74 74 74 74 74 74 74 74 74 74 74 80 8A 8A 8A 8B 8A 8B 8B 8B 8B 8B 8A 8A 8A 8A 74 73 74 74 74 74 74 74 74 74 74 74 74 74 74 80 80 8A 8A 8A 8A 8B 8B 8A 8B 8B 8A 8A 8A 8A 74 74 74 74 74 74 74 73 74 74 73 74 74 74 74 80 80 8A 8A 8B 8B 8B 8B 8B 8B 8B 8A 8B 8A 8A 74 74 74 74 74 74 74 74 74 74 75 74 74 74 74 74 80 8A 8B 8B 8B 8B 8B 8B 8B 8A 8A 8A 8B 8A 8B 74 74 74 74 74 74 74 74 74 74 74 74 74 74 74 80 8B 8B 8B 8B 8B 8A 8B 8A 8A 8A 8B 8B 8B 8B 74 74 74 74 74 74 74 74 74 74 74 74 74 74 74 80 80 8B 8B 8B 8B 8B 8A 8B 8A 8A 8A 8B 8B 8B 74 74 74 74 74 74 74 74 74 74 74 74 74 74 74 80 80 8B 8B 8B 8B 8B 8B 8A 8A 8A 8B 8A 8C 8B 74 75 74 74 74 74 74 74 74

Eu os coloquei em uma lista, converti para hexadecimal e depois para decimal, trabalhei os dados da forma que eu precisava e agora tenho que voltar para o formato original.
Minha lista atual está mais ou menos assim:

 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 177, 
177, 177, 177, 177, 177, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129, 129

Preciso voltar essa lista no formato original para criar um arquivo.bin novamente do jeito que era inicialmente.

Você chegou a tentar gerar uma lista com o valor original e depois uma com o valor formatado?
