yes you need to hex edit the client and make this too
Code:
#if defined(_MULTIPLATFORM77)
#define _MULTIPLATFORM76
#define ITEMS_PATH std::string("77")
#define CLIENT_VERSION_ITEMS 3
#define CLIENT_VERSION_MIN 602 <<<-- here fake protocol
#define CLIENT_VERSION_MAX 602 <<<-- here fake protocol
#define CLIENT_VERSION_STRING "In order to play download relicaria's custom client" <<<<-- the string that's related to send the message about what protocol or client the player should be use to connect
if this works mark my answer as best answer also update the thread tittle with the word Solved it will help others in a future
