How i can improve login port at client?

Open ProjectG.exe in a hex editor, do an integer search for the default login server port number and alter the value as you see fit.

I'm trying to search.
But no.


Thank you very much for answers.

I suspect you ran a normal character-based search (like you do for strings or IP addresses). You won't find the number that way since your editor looks for a normal "text" instead of an encoded number.

Just to make sure you didn't search for the wrong port number... 10103 should be the default login server port that is also present in the client executable.

Depending on your hex-editor, it's also possible the program doesn't support integer searches.
