i know what he means but thats just pointless. actually if the username not exist in the database then its unable to login. well i know the password check is not exist in this version so i made this
made an api for login and registration
made a launcher what is checks the username and password combo (i used md5, its just meh but doesnt matter in the case)
packed bless.exe from Binaries\Win64\ with themida and ripped some critical engine files from the pak files into the new binary, in the same time i emulate them in memory so basicly unable to launch my client with haxed - mixed solution if you dont know what are you exactly doing or not an expert reverse engineer.
however with vanilla client is able to login but its kinda pointless (my client is translated to my language), but its can be protected with a simple reverse proxy
