NHP TURBO 3.6 BY PARCHE NEGRO

Después de un largo tiempo, logré terminar el desamble de este mítico software, como lo hice,, ufff no lo sabes,, ahora leerás el proceso que me llevo.

INTRODUCCION

Tío Parche como muchos de nosotros lo tratamos por cariño, fue uno de los programadores de la linea prisma, armando y modificando softwares para la distribucion en Chile.

Después de que comencé con la programación en assembler y empece con mayores conocimientos sobre el tema. decidí desamblar el nhp 3.6.

Cual era la idea… Más que nada, saber el comportamiento y como trabajaba la mayoría de los sistemas que creo el tio.

DESEMPOLVANDO EL NHP

Este software contiene en su interior mucha información importante que ejecuta en primer y segundo plano en milisegundos.

Archivos:
A-. KEM2 -> Copia la rom la ram, para realizar los cambios de velocidad de grabación de la data a la cinta.
B -. código de la data que sera grabado en la cinta.
B1-. Loader -> Data que contiene la portada y ejecución de carga de la data al atari.
B2-. Pagina 7 -> Data que contiene la portada de muestra al comienzo de la cinta que aparece — PRISMA —
B3-. Data de carga de loader, donde indica cuantos bytes debe cargar.
esos son algunos datos que contiene la estructura en su desamble. Ahora pasaremos a conocer el código en si.

KEM2.ASM

Este codigo cumple con la funcionalidad de copiar la roma a la ram para poder modificar algunos valores que será, usados dentro de las operaciones.
Es ocupado tanto por el software principal como el código que se va cargando en la cinta.

LOADER

Este loader esta configurado solo en bytes, porque es la data que se anexa al codigo principal y se graba en la cinta.

Contiene el kem2 página 7 página 4 y el loader en si.
