Hola amigos.

La motivación a hacer hacks para Rakion Latino cada día se ha vuelto más un hecho, especialmente con el siguiente código que vamos a procesar a continuacón:

.386
.model flat,stdcall
option casemap:none
include windows.inc
include masm32.inc

  include gdi32.inc
  include user32.inc
  include kernel32.inc

  include oleaut32.inc
  include dialogs.inc
  includelib masm32.lib
