+ * DummyBrain is example how you create you own cpu brain to translate from
+ * cpu to intel assembler, I have not add DummyBrain to the loader it is not
+ * need it in our example. When you write you own brain, it must be setup in

+ * need the brain you have writen so you do not need setup it there then.
+ *
+ * input param:
+ * cpu_buffer : the memory buffer with loaded program we whant translate
+ * cpu_pos : the positions in the cpu_buffer
+ * cpu_size : the alloced memory size of the cpu_buffer
+ * BaseAddress : the virtual memory address we setup to use.
+ * cpuarch : the sub arch for the brain, example if it exists more one
+ * cpu with same desgin but few other opcode or extend opcode
+ * outfp : the output file pointer
+ *
+ * mode : if we should run disambler of this binary or
+ * translate it, Disambler will not calc the
+ * the row name right so we simple give each
+ row a name. In translations mode we run a
+ * analys so we getting better optimzing and
