Modify entergame window

[mct]

I want modify the "enter game window". I need only show Account & Password.

The client connect directly with my server.

Example:
$host = myhostname
$protocol = 8
$port = 7171

I need hide these options.

Here is the question: ¿I need compile? or I can make this only writting the lua code?

Perfect, Now Works!!!

With editing lua code (entergame.lua) and entergame.otui.

I downloaded the libraries, mingw & codeblocks for nothing...
