Osea tengo un programa con un cuadro que muestra un numero y y un boton para aumentar , si abro el cheat engine encuentro el valor y lo cambio.
Lo que quiero hacer es plasmar el valor de otro programa y que muestre en el cuadro por ejemplo el valor de la velocidad de un juego de carreras , encuentro el valor de velocidad que es 32  en cheat engine  CARRERA.EXE_00A0800=32
pero no puedo abrir otro proceso en cheat engine
yo quiero plasmar en PROGRAMA.EXE_barra=CARRERA.EXE_00A0800=32


pd:todo es codigo inventado para ilustrar

supongamos que tengo 2 juegos ejecutandose en ventanas diferentes osea procesos diferentes  , uno es de pelea y otro de carreras.
tengo los valores de  la vida de los luchadores y la velocidad del auto y quiero que la velocidad con la que va el auto sea la cantidad de vida de el luchador.

osea que el valor hexadecimal donde se almacena la velocidad del auto tambien sea de la vida del otro programa(el juego de pelea ). es decir que se plasme ese valor de velocidad  donde se almacena la vida del luchador.

osea si en el juego del auto desaselero en el de pelea la vida de mi jugador se decrementoa y si acelero aumenta.

Los virus solo se ejecutan por archivos con extension .exe? o pueden ejecutarse dentro de un mp3 o jpg o otra extension.

Por que cuando uno camufla un keylogger dentro de una imagen por ej. la imagen tiene la extension exe y es muy facil que la victima se dee cuenta,pero si cambiamos la extension de la imagen con el virus a jpg o png  se ejecutara la imagen pero el virus lo hara o no?

no entiendo mucho en ensamblador
es un codigo de c/c++

es de un emulador de sega llamado gens que emula el procesador 68k
este es star_68k.h

mmm.. entendi mas o menos pero podrian explicarme mas detalladamente como podria hacerse eso, no se mucho de shell codes ni hooking.

me refiero a meter un programa dentro de una imagen o musica  , que el programa estee dentro de un .mp3 o .jpg y que se ejecute sin que el archivo sea .exe

Los virus solo se ejecutan por archivos con extension .exe? o pueden ejecutarse dentro de un mp3 o jpg o otra extension.

Por que cuando uno camufla un keylogger dentro de una imagen por ej. la imagen tiene la extension exe y es muy facil que la victima se dee cuenta,pero si cambiamos la extension de la imagen con el virus a jpg o png  se ejecutara la imagen pero el virus lo hara o no?

Alguien aqui es un experto en game maker que me pueda ayudar entender este programa mas a fondo y compartir conocimientos.
diganme que dias y horarios estan libres para chatear sobre game maker.

yo tengo entendido que es un conjunto de reglas para resolver un problema ,diganme si estoy en lo correco no sacando de wikipedia con sus propias palabras.

quiero extraer los sonidos ya se a midi o wav de un archivo .jar osea los juegitos para celular que soporten java.

cuando quiero editar un valor de un juego por ej las balas le pongo un balor alto para que no se me cabe rapido pero no sirve por que ese valor vuelve a su valor original.
osea tengo 40 valas y le  pongo 9999 pero no sirve por que ensegida se cambia a 40.
A que se deve eso que un valor no se pueda modificar.
