Make SPRX Work on CEX And DEX

So Your SPRX will not work on CEX Because in your Write Process you are using a syscall (905) which only works on DEX

So we have 2 Ways of Changing so your sprx will work on to CEX

• 1) GoPros Way - Credits to him
  void *Memcpy(void *dst0, const void *src0, size_t len0)
  {
  char *dst = (char *)dst0;
  char *src = (char *)src0;
  void *save = dst0;
  while (len0--)
  *dst++ = *src++;
  return save;
  }
  int write_process(void* destination, const void* source, size_t size)
  {
  Memcpy(destination,source,size);
  }
  
• 2) Using Syscall 201 (used on CEX)
  int32_t write_process(uint64_t ea, const void * data, uint32_t size)
  {
  system_call_4(201, (uint64_t)sys_process_getpid(), ea, size, (uint64_t)data);
  return_to_user_prog(int32_t);
  }
  

i Personally use Syscall 201 for CEx however go pros way works just as good

Entonces su SPRX no funcionará en CEX Porque en su Proceso de Escritura está usando un syscall (905) que solo funciona en DEX.

Por lo tanto, tenemos 2 formas de cambiar para que su sprx funcione con CEX

• 1) GoPros Way - Créditos para él
  void * Memcpy (void * dst0, const void * src0, size_t len0)
  {
  char * dst = (char *) dst0;
  char * src = (char *) src0;
  void * save = dst0;
  while (len0--)
  * dst ++ = * src ++;
  volver guardar
  }
  int write_process (void * destination, const void * source, size_t size)
  {
  Memcpy (destination, source, size);
  }
  
• 2) Utilizando Syscall 201 (usado en CEX)
  int32_t write_process (uint64_t ea, const void * data, uint32_t size)
  {
  system_call_4 (201, (uint64_t) sys_process_getpid (), ea, tamaño, (uint64_t) data);
  return_to_user_prog (int32_t);
  }
  

Personalmente uso Syscall 201 para CEx.

thanks bro god relase

bro when I add that code to my sprx, I do not load it. I have to do a dex version and another cex, or does 201 work for both?
